SUMMARY:Probing Extrasolar Planet Atmospheres Through Transmission Spectros
 copy - Eliza Kempton
DESCRIPTION:Eliza Kempton\, Grinnell CollegeRésumé/abstract:Much has been
  learned about exoplanet atmospheres in recent years. For transiting extra
 solar planets\, transmission spectroscopy -- measurements of the spectrum 
 of stellar light transmitted through the planetary atmosphere during trans
 it -- has been a valuable tool for constraining atmospheric properties. To
  date\, transmission spectroscopy has been used as a tool for constraining
  atmospheric composition\, cloud structure\, hazes\, and winds in a variet
 y of exoplanetary atmospheres. In this talk I will focus on recent modelin
 g and observational results that have pushed the capabilities of this meth
 od. The first is the use of transmission spectra to constrain the atmosphe
 ric properties of the transiting super-Earth GJ 1214b. The second is the u
 se of Doppler shifted transmission spectra to measure wind speeds in tidal
 ly locked hot Jupiters.Ce séminaire est présenté par le groupe astronom
 ie et astrophysique du Département de physique de l'Université de Montr
 éal.
