Detecting General Relativistic Orbital Precession in Transiting Hot Jupiters

G. Antoniciello, L. Borsato, G. Lacedelli +3

Both classical and relativistic weak-field and slow-motion perturbations to planetary orbits can be treated as perturbative corrections to the Keplerian model. In particular, tidal…

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…

TESS re-observes the young multi-planet system TOI-451: refined ephemeris and activity evolution

Oscar Barragán, Suzanne Aigrain, Edward Gillen +1

We present a new analysis of the light curve of the young planet-hosting star TOI 451 in the light of new observations from TESS Cycle 3. Our joint analysis of the transits of all…

CHEOPS observations of the HD 108236 planetary system: A fifth planet, improved ephemerides, and planetary radii

A. Bonfanti, L. Delrez, M. J. Hooton +106

The detection of a super-Earth and three mini-Neptunes transiting the bright ( = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently reported on the basis of TESS and…

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…
