Job description

Description

Description:

Exoplanet-host stars with planets at short separations can influence each other (commonly termed the star- planet interaction or SPI), via a variety of mechanisms. Understanding SPI in exoplanet host stars is thus crucial for understanding the evolution of planets (and/or planetary systems) and their host stars, but observational evidence for SPI is generally scarce. An important signature of SPI is UV emission, and time-resolved FUV spectroscopy with HST/COS has provided compelling evidence for, and details of, the SPI phenomenon in HD189733, which has a Jupiter-mass planet. Prospective candidate will work on an analysis of the UV emission from star-exoplanet systems, using archival data from GALEX and HST, as well as a new HST program using COS spectroscopy to investigate SPI in the exoplanet host star Kepler-535, which hosts a 0.2 Jupiter-radius planet.
