The spacecraft aims to measure stars and planets and build the largest (to date) 3D catalog. It used 3 important sensors; Astro\, BP/RP\, and RVS\, which allowed us to gather data on a star’s position\, brightness\, and motion. The Gaia mission collected astronomical data on over 1 billion stars within its range such as their position as well as their estimated temperature and rotation period. The data provided by Gaia can then be used to create accurate stellar maps of our local neighborhood. Gaia’s data is open for the public to use\, taking such data we’re able to determine in bulk the location of stars through parallax right ascension and declination. As for the star’s color\, we can make a good estimate of its color through the black body spectrum caused by the star’s temperature. A blackbody spectrum is a spectrum of the wavelengths of radiation\, by taking the ones that are in the visible light range we can create a good estimate of what the star would look like if we could see it for ourselves. Through a code in Python\, we can feed a bulk amount of data generated by Gaia to create a 3D map for any chunk of data that we want to analyze. \n  \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Ing Xhu Lim is an undergraduate student at the University of Toronto.

The sunlike star was thought to be an old Population II star with an age of at least 10 Gyrs due to its kinematics\, however\, it has indicators of youth leading Astronomers to believe the star is a Blue Straggler – a star that has gained mass from a close by companion. This would cause HD 165401 to appear bluer and have a higher magnetic activity compared to a typical Population II star. By visually observing the star using the Keck II telescope\, along with a 17 yearlong Radial Velocity (RV) dataset\, we discovered a faint companion HD 165401 Ab. Analyzing this data\, we identified HD 165401 Ab as a whitedwarf with a mass of M = and a cooling age of = 3 Gyrs. This means that it has been only 3 Gyrs since HD 165401 has become a white dwarf and was likely a 5-solar mass star before leaving the main sequence. HD 165401 A would have been smaller in comparison to its current state and gained mass during the planetary nebula phase of HD 165401 Ab\, effectively prolonging its main sequence lifetime. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Tabassom Madayen is a fourth-year undergraduate student at the University of Toronto Mississauga doing Astronomical specialist. \nFor the past year she has been doing research with Dr Lea Hirsch on discovery and characterization of two nearby binary systems.  With previous experience working on contact binary star systems\, her current field of study is stellar astronomy which contains discovery and classification of stars in binary systems. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Ziyyad Ali is a fourth-year undergraduate student at the University of Toronto Mississauga doing an Astronomy major\, Physics\, and a Computer Science minor. \nFor the past year he has been doing research with Dr Lea Hirsch on the discovery and characterization of two nearby binary systems.

The underlying physics behind these dark components is unknown\, but we can constrain their properties by observing how they affect visible matter\, searching for clues for how to develop more fundamental descriptions of this “dark side” of the Universe. This talk will give an overview of how we can use measurements from galaxy surveys\, which map the distribution of matter in the Universe\, to learn about dark energy\, dark matter\, and gravity and will describe the current state-of-the-art results from an ongoing experiment called the Dark Energy Survey. \nBio: Jessie Muir is a Postdoctoral Fellow at the Perimeter Institute for Theoretical Physics in Waterloo\, Ontario. Originally from Romeo\, Michigan\, a suburb of Detroit\, Jessie completed her undergraduate studies at Michigan State University\, masters work at the University of Cambridge as a Marshall Scholar\, and her PhD at the University of Michigan. She has previously done postdoctoral research as a Porat Fellow at Stanford University. Jessie works on research at the intersection of cosmology theory and data analysis with the goal of using measurements of the large-scale properties of the Universe to learn about fundamental physics. As part of the Dark Energy Survey scientific collaboration\, Jessie recently co-led the experiment’s analysis of galaxy clustering and weak gravitational lensing to test for physics beyond the standard cosmological model\, and has contributed to the development of strategies for protecting cosmology analyses from unconscious experimenter bias. \nJoin us on online using ZOOM: CLICK TO JOIN\nCampus Map (click to download)\nPark in lot P4 or P8.  Enter Building C10 (Recreation\, Athletics & Wellness Centre).

In this profusely illustrated\, non-technical presentation\, Prof. Percy will provide a gentle overview of astronomy by touching on a wide variety of common misconceptions from everyday life (e.g.\, the cause of the seasons)\, about our solar system\, black holes\, UFOs\, and the Big Bang. Prof. Percy will emphasize the many causes of these misconceptions since these same causes are responsible for much of the other misinformation and “fake news” that is so rampant in today’s society. \nProf. Percy is an active Professor Emeritus in Astronomy & Astrophysics\, and in Science Education at the Ontario Institute for Studies in Education (OISE-UT). He was a founding faculty member of the University of Toronto Mississauga in 1967 and retired from there in 2007. His research deals with the nature and evolution of stars as deduced from variable stars\, which change in brightness. He is a supervisor and mentor of undergraduate research students and is known internationally for encouraging and facilitating research in variable star astronomy by skilled amateur astronomers. Prof. Percy is deeply engaged in astronomy outreach: he gives courses for later-life learners and public lectures in libraries and other venues that explore the interdisciplinary nature of astronomy. He also promotes and supports the teaching of astronomy in schools.

Dr Samantha Lawler DESCRIPTION:Speaker: Dr. Samantha Lawler\, University of Regina \nTitle: “Megaconstellations of satellites are about to ruin the night sky for everyone” \nAbstract:\nSeveral companies are starting to launch megaconstellations of thousands of communication satellites (satcons)\, which would increase the number of active satellites in Low Earth Orbit at least twenty-fold in the next few years.  SpaceX’s Starlink satcon is currently largest (over 2\,000 satellites) and is adding 60 new satellites every couple of weeks.  While these satcons do allow internet access in many underserved rural and remote locations\, the costs are prohibitively high for all but the most well-off customers.  These thousands of satellites each reflect sunlight\, causing serious problems for research astronomy\, and making anthropogenic light pollution a fully global phenomenon that cannot be escaped anywhere on Earth.  Our recent simulations show that because of geometry and the chosen satellite orbits\, latitudes near 50 degrees N and S will see the worst light pollution from these satcons\, with hundreds of naked-eye visible satellites all night long in the summer.  These satellites also contribute to significant atmospheric pollution\, both on launch and re-entry\, contribute to diffuse sky emission\, and drastically increase the very real threat of Kessler Syndrome.  I will talk about how these satellites will affect stargazers and astronomers worldwide\, and what you can do to help mitigation efforts. \nBio:\nSamantha Lawler studies the orbits of Kuiper Belt objects\, exoplanets\, and dust disks using optical and IR observations and dynamical simuations.  She completed her undergrad degree at Caltech\, followed by two years there working with early Spitzer Space Telescope data\, and then earned a Master’s degree from Wesleyan University.  She completed her PhD at UBC\, a postdoc at UVic\, and then a Plaskett Fellowship at NRC-Herzberg\, all while raising kids and getting slowly drawn further into farm life with her partner.  Somehow\, magically\, she found an amazing balance: she is now an assistant professor of astronomy at Campion College at the University of Regina\, and lives on a 150 acre farm where she helps raise goats\, chickens\, and organic vegetables with her partner and kids\, while enjoying and trying to protect the huge prairie skies. \nZoom link to meeting URL:https://rasc.optunia.me/event/speaker-night-dr-samantha-lawler/ CATEGORIES:Speaker Night ATTACH;FMTTYPE=image/jpeg:https://rasc.optunia.me/wp-content/uploads/2022/03/Lawler500.jpg END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Toronto:20220513T193000 DTEND;TZID=America/Toronto:20220513T213000 DTSTAMP:20260419T195313 CREATED:20220128T212116Z LAST-MODIFIED:20220509T173557Z UID:1791-1652470200-1652477400@rasc.optunia.me SUMMARY:Potpourri Meeting DESCRIPTION:Potpourri Meeting – various talks by members \nShriya Naik  Upcoming Astronomical Events in May \nRick Veregin   Review of L-eNhance DuoBand Filter for Astrophotography in Light Polluted Skies \nRon Macnaughton    Encouraging Durable Astronomy Clubs in High Schools. \nTom Otvos    An Equatorial Platform for Short-Duration Tracking \nEquatorial platforms provide a convenient way to track objects in the sky on Alt-Az or Dobsonian telescopes.

The discovery of biological adaptation to extreme conditions makes it very likely that variations on biology will exist on moons and planets around many of the billions of Sun-like stars in the Milky Way. The talk addresses the issue of even more unusual forms of life\, where the biological basis may be different or unrecognizable. \nBIOGRAPHY: Chris Impey is a University Distinguished Professor of Astronomy at the University of Arizona. He has 210 refereed publications on observational cosmology\, galaxies\, and quasars\, and his research has been supported by $20 million in NASA and NSF grants.
