[AstroTours Keynote] Hot Rocks and Host Stars: Revelations of rocky exoplanets in the era of James Webb

Please note that this event is not run by the Royal Astronomical Society of Canada - Toronto Centre. Please contact the organizers for more information.

Join us at the AstroTours Keynote Talk! This event is FREE and open to all. NO PRIOR REGISTRATION REQUIRED!! Our Keynote features assistant astronomer at the Space Telescope Science Institute, Dr Hannah Diamond-Lowe, and her work on exoplanets orbiting M dwarf stars!

Talk Abstract:

Small planets with masses and radii similar to the Earth are the most common category of planet in the Milky Way, and they are also the most difficult to study. Four years into the launch of the James Webb Space Telescope we are peering closer than ever before at our rockiest exoplanetary neighbors. These efforts have uncovered roasting airless surfaces, frustrating contamination by stellar hosts, and puzzling instrumental effects. Decoding what it all means, and whether these worlds host atmospheres that may be hospitable to life, is an active area of research, sometimes with more questions than answers. Come enjoy a journey to our closest rocky neighbors orbiting curious M dwarf stars.
 

About the Speaker:
I am an Assistant Astronomer at Space Telescope Science Institute. I characterize small exoplanet atmospheres with ground- and space-based observatories. I am the PI of the Hot Rocks Survey, a large program on the James Webb Space Telescope to test 9 terrestrial exoplanets orbiting nearby M dwarfs for atmospheres. My research focuses on investigating the atmospheres of small exoplanets and the high-energy output of their host M stars.
