Abstract: An ever growing number and diversity of short-period planet atmospheres can now be probed using the planetary-transit spectroscopy (transmission spectroscopy of the atmosphere when the planet crosses the disc of the star). Detections over the last decade have mainly been hot Jupiter gas giant planets, which have provided the first measurements of composition, structure, and dynamics of exoplanet atmospheres. I will discuss the current state of the art for these observations and what can be learned from these measurements, with more details on our large set of observations with the Hubble Space Telescope.
