TOI-3493 b: A planet with a Neptune-like density transiting a bright G0-type star

P. Chaturvedi, E. Goffo, D. Gandolfi +23

We report the discovery of TOI-3493 b, a sub-Neptune-sized planet on an 8.15-d orbit transiting the bright (V=9.3) G0 star HD 119355 (aka TIC 203377303) initially identified by NAS…

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…

TOI-2458 b: A mini-Neptune consistent with in situ hot Jupiter formation

Ján Šubjak, Davide Gandolfi, Elisa Goffo +33

We report on the discovery and spectroscopic confirmation of TOI-2458 b, a transiting mini-Neptune around an F-type star leaving the main-sequence with a mass of $M_\star=1.05 \pm…

TOI-757 b: an eccentric transiting mini-Neptune on a 17.5-d orbit

A. Alqasim, N. Grieves, N. M. Rosário +129

We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star ( mag) discovered by the TESS…

Revisiting the dynamical masses of the transiting planets in the young AU Mic system: Potential AU Mic b inflation at 20 Myr

M. Mallorquín, V. J. S. Béjar, N. Lodieu +26

Understanding planet formation is important in the context of the origin of planetary systems in general and of the Solar System in particular, as well as to predict the likelihood…
