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…

Hot planets around cool stars -- two short-period mini-Neptunes transiting the late K-dwarf TOI-1260

I. Y. Georgieva, C. M. Persson, O. Barragán +56

We present the discovery and characterization of two sub-Neptunes in close orbits, as well as a tentative outer planet of a similar size, orbiting TOI-1260 - a low metallicity K6V…

Masses and compositions of three small planets orbiting the nearby M dwarf L231-32 (TOI-270) and the M dwarf radius valley

Vincent Van Eylen, N. Astudillo-Defru, X. Bonfils +69

We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf ( pc, M, R), which hosts three transiting p…

K2-280b -- a low density warm sub-Saturn around a mildly evolved star

Grzegorz Nowak, Enric Palle, Davide Gandolfi +57

We present an independent discovery and detailed characterisation of K2-280b, a transiting low density warm sub-Saturn in a 19.9-day moderately eccentric orbit (e = 0.35_{-0.04}^{+…

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…

Mass determinations of the three mini-Neptunes transiting TOI-125

L. D. Nielsen, D. Gandolfi, D. J. Armstrong +77

The Transiting Exoplanet Survey Satellite, TESS, is currently carrying out an all-sky search for small planets transiting bright stars. In the first year of the TESS survey, steady…
