Radii, masses, and transit-timing variations of the three-planet system orbiting the naked-eye star TOI-396
A. Bonfanti, I. Amateis, D. Gandolfi +38
TOI-396 is an F6V star () orbited by three transiting planets. The orbital periods of the two innermost planets are close to the 5:3 commensurability ( d…
On the behaviour of spin-orbit connection of exoplanets
Bruno L. Canto Martins, Yuri S. Messias, Maria I. Arruda Gonçalves +5
Star-planet interactions play, among other things, a crucial role in planetary orbital configurations by circularizing orbits, aligning the star and planet spin and synchronizing s…
A dearth of close-in planets around rapidly rotating stars or a dearth of data?
Y. S. Messias, L. L. A. de Oliveira, R. L. Gomes +4
A dearth of close-in planets orbiting rapid rotators was reported almost a decade ago. According to this view only slowly spinning stars with rotation periods longer than 5-10 days…
TOI-220 : a warm sub-Neptune discovered by TESS
S. Hoyer, D. Gandolfi, D. J. Armstrong +77
In this paper we report the discovery of TOI-220 , a new sub-Neptune detected by the Transiting Exoplanet Survey Satellite (TESS) and confirmed by radial velocity follow-up obse…
TOI-269 b: An eccentric sub-Neptune transiting a M2 dwarf revisited with ExTrA
M. Cointepas, J. M. Almenara, X. Bonfils +59
We present the confirmation of a new sub-Neptune close to the transition between super-Earths and sub-Neptunes transiting the M2 dwarf TOI- 269 (TIC 220479565, V = 14.4 mag, J = 10…
Three planets transiting the evolved star EPIC 249893012: a hot 8.8-M super-Earth and two warm 14.7 and 10.2-M sub-Neptunes
D. Hidalgo, E. Pallé, R. Alonso +57
We report the discovery of a new planetary system with three transiting planets, one super-Earth and two sub-Neptunes, that orbit EPIC\,249893012, a G8\,IV-V evolved star ($M_\star…
