Characterizing the Coldest Exoplanets - Andrew Skemer (SETI Talks 2016)
Δημοσιεύτηκε στις 29 Αυγ 2016
The
coldest known exoplanets are still much hotter than the gas giant
planets in our own Solar System. Pushing to colder temperatures
requires observing in the thermal infrared (3-5 microns) where
self-luminous gas-giants peak in brightness.
Dr. Skemer will
present observational studies characterizing the atmospheres of the
coldest exoplanets and the coldest brown dwarf. These observations
include a planet whose metallicity is higher than its host star, and a
250 K brown dwarf which shows signs of water clouds. Additionally, he
will describe a new instrument that can obtain spectroscopy of directly
imaged planets from 3-5 microns.
