The Short Period Planets Group S(u)PerP(i)G is an international collaboration to find, confirm, and study extrasolar (or exo-) planets orbiting very close to their host stars and in short periods (< 1 day). Already, many candidate planets have been found by our group and others using data from the Kepler and K2 missions.
From wispy gas giants on the verge of disruption to tiny rocky bodies already falling apart, short period exoplanets pose a severe challenge to theories of planet formation and evolution, but they dominate observational constraints on planetary composition, internal structure, meteorology, and more. So understanding these planets is crucial for understanding planets in general.
A full list of all of our ultra-short-period planet candidates can be found here.
Our collaboration consists of experts in exoplanetary transit analysis, radial velocity observations, and planetary dynamics.
