WASP-121b optical phase curve
Listed in IVOA Registry (Virtual Observatory)
We present the analysis of TESS optical photometry of WASP-121b, which reveals the phase curve of this transiting ultra-hot Jupiter.
Description
Its hotspot is located at the sub-stellar point, showing inefficient heat transport from the dayside (2870+/-50K) to the nightside (<2500K at 3{sigma}) at the altitudes probed by TESS. The TESS eclipse depth, measured at the shortest wavelength to date for WASP-121b, confirms the strong deviation from blackbody planetary emission.
Our atmospheric retrieval on the complete emission spectrum supports the presence of a temperature inversion, which can be explained by the presence of VO and possibly TiO and FeH. The strong planetary emission at short wavelengths could arise from an H^-^ continuum.
