An Analysis of Transiting Hot Jupiters Observed with K2: WASP-55b and WASP-75b

We present our analysis of the K2 short-cadence data of two previously known hot Jupiter exoplanets: WASP-55b and WASP-75b. The high precision of the K2 light curves enabled us to search for transit timing and duration variations, rotational modulation, starspots, phase-curve variations and additional transiting planets. We identified stellar variability in the WASP-75 light curve which may be an indication of rotational modulation, with an estimated period of 11.2 ± 1.5 days. We combined this with the spectroscopically measured v\sin ({i}_* ) to calculate a possible line of sight projected inclination angle of {i}_* =41^\circ +/- 16^\circ . We also perform a global analysis of K2 and previously published data to refine the system parameters.
