TL;DR
This paper reports the discovery of WASP-135b, a highly irradiated, inflated hot Jupiter orbiting a G5V star, with detailed measurements of its properties and potential star-planet interactions.
Contribution
The paper presents the discovery and characterization of a new hot Jupiter, including its physical parameters and possible angular momentum transfer effects.
Findings
WASP-135b has a radius of 1.30 Rjup and a mass of 1.90 Mjup.
The planet orbits its star every 1.401 days.
Weak evidence suggests angular momentum transfer from planet to star.
Abstract
We report the discovery of a new transiting planet from the WASP survey. WASP-135b is a hot Jupiter with a radius of 1.30 pm 0.09 Rjup, a mass of 1.90 pm 0.08 Mjup and an orbital period of 1.401 days. Its host is a Sun-like star, with a G5 spectral type and a mass and radius of 0.98 pm 0.06 Msun and 0.96 pm 0.05 Rsun respectively. The proximity of the planet to its host means that WASP-135b receives high levels of insolation, which may be the cause of its inflated radius. Additionally, we find weak evidence of a transfer of angular momentum from the planet to its star.
