Planetary scientist Jade Checlair of the University of Chicago and
her colleagues investigated whether tidally locked planets in
habitable zones could ever enter snowball states in which ice
covers their entire surface.

Biography
I received my B.Sc. in Physics from the University of Toronto in
2016, and came to the University of Chicago that same year. I am
developing statistical habitability tests we could use with future
direct imaging instruments (LUVOIR and/or HabEx). In particular,
I am interested in ways to test the concept of the habitable zone
and its boundaries using large samples of exoplanets. Currently,
I am working on how we could test for a functioning silicate-
weathering feedback on habitable exoplanets. My goal is to determine
the feasibility of those statistical tests, by exploring how many
exoplanets we would need to observe in order to conduct them given
observational constraints. I am also studying the climate of
potentially habitable tidally locked planets, which may be common
around M-dwarf stars. Currently, I am trying to determine whether
those planets can go through climate limit cycles near the outer
edge of the habitable zone.
