While the sample of confirmed exoplanets continues to grow, the population of transiting exoplanets around early-type stars is still limited.
Description
These planets allow us to investigate the planet properties and formation pathways over a wide range of stellar masses and study the impact of high irradiation on hot Jupiters orbiting such stars. We report the discovery of TOI-615b, TOI-622b, and TOI-2641b, three Saturn-mass planets transiting main sequence, F-type stars.
The planets were identified by the Transiting Exoplanet Survey Satellite (TESS) and confirmed with complementary ground-based and radial velocity observations. TOI-615b is a highly irradiated (~1277F_{Earth}_) and bloated Saturn-mass planet (1.69^+0.05^_-0.06_R_Jup_ and 0.43^+0.09^_-0.08_M_Jup_) in a 4.66 day orbit transiting a 6850K star. TOI-622b has a radius of 0.82^+0.03^_-0.03_R_Jup_ and a mass of 0.30^+0.07^_-0.08_M_Jup_ in a 6.40 day orbit.

Despite its high insolation flux (~600F_{Earth}_), TOI-622b does not show any evidence of radius inflation. TOI-2641b is a 0.39^+0.02^_-0.04_M_Jup_ planet in a 4.88 day orbit with a grazing transit (b=1.04^+0.05^_-0.06_) that results in a poorly constrained radius of 1.61^+0.46^_-0.64_R_Jup_. Additionally, TOI-615b is considered attractive for atmospheric studies via transmission spectroscopy with ground-based spectrographs and JWST.
Future atmospheric and spin-orbit alignment observations are essential since they can provide information on the atmospheric composition, formation and migration of exoplanets across various stellar types.
