We report the discovery of WASP-34b, a sub-Jupiter-mass exoplanet transiting its 10.4-magnitude solar-type host star (1SWASP J110135.89-235138.4; TYC 6636-540-1) every 4.3177 days in a slightly eccentric orbit (e = 0.038 ± 0.012). We find a planetary mass of 0.59 ± 0.01 MJup and radius of 1.22 +0.11 −0.08 RJup. There is a linear trend in the radial velocities of 55 ± 4m s −1 y −1 indicating the presence of a long-period third body in the system with a mass >0.45 MJup at a distance of >1.2 AU…

Mass-loss rates for transiting exoplanets

On a Possible Solution to the Tidal Realignment Problem for Hot Jupiters
• Geology, Physics
The Astrophysical journal
• 2021
The model implies that hot Jupiters orbiting cool stars are probably not in immediate danger of being devoured by their host stars while they are on the main sequence, and a testable prediction of the model is that hot Jupiter hosts with orbital periods shorter than 2–3 days should have obliquities much smaller than 1°.
