15th International Astronomical Consortium for High Energy Calibration (IACHEC) Meeting
In light of the continued troubled times and the uncertainty of when our institutions may allow travel again, we are postponing the 15th IACHEC meeting for next year on 26–29 April 2021. We will still be meeting at the...
White Dwarfs as Probes of the Evolution of Planets, Stars, the Milky Way and the Expanding Universe
This program is motivated by the recent observational insights concerning white dwarfs as individuals and as a population, based on the astrometry from Gaia and large photometric (e.g. Kepler,TESS, ZTF) and spectroscopic...
White Dwarfs from Physics to Astrophysics
Astrometric, photometric and spectroscopic all-sky surveys provide the first complete, unbiased view of the Galactic population of the most abundant type of stellar remnants: white dwarfs.
LISA Canada 2021 Workshop
The Laser Interferometer Space Antenna (LISA) mission is a space-based gravitational wave interferometer planned for launch in 2032. It promises major advances across a wide range of fields in physics and astronomy...

AAVSO's free webinar is from 2:00 pm to about 3:00 pm ET, and features Dr. David Whelan (Austin College) presenting on "Classifying Algol C, the Non-Eclipsing Member of the beta Persei System."
SKA Science Meeting: A Precursor View of the SKA Sky
The SKA Science conference 2021, “A precursor’s view of the SKA sky”, is a fully virtual event that has been designed to allow participation from all countries and timezones. The format of the meeting will include...
Fundamentals of Gaseous Halos
Gas in the halos of galaxies dominates the universe's baryon budget, traces its dark-matter potential wells, and supplies the fuel for star formation. Circumgalactic gas has also long been suspected to regulate galaxy...
Multiwavelength Probes of Galactic Atmospheres
The circumgalactic medium (CGM) can be viewed as an atmosphere that surrounds a galaxy and sustains star formation within it. Much of what we know about the CGM has come from absorption-line spectroscopy, mainly in the...
Thirty Meter Telescope (TMT) Science Forum
The annual Thirty Meter Telescope (TMT) Science Forum gathers members of the international astronomical community to meet, collaborate, and plan for future TMT science programs. It is the premier opportunity to learn...
