A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776

R. Luque, L. M. Serrano, K. Molaverdikhani +63

We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54+-0.03 Msun) detected during Sector 10 o…

TKS III: A Stellar Obliquity Measurement of TOI-1726 c

Fei Dai, Arpita Roy, Benjamin Fulton +43

We report the measurement of a spectroscopic transit of TOI-1726 c, one of two planets transiting a G-type star with = 6.9 in the Ursa Major Moving Group (400 Myr). With…

The TOI-763 system: sub-Neptunes orbiting a Sun-like star

M. Fridlund, J. Livingston, D. Gandolfi +51

We report the discovery of a planetary system orbiting TOI-763 (aka CD-39 7945), a , high proper motion G-type dwarf star that was photometrically monitored by the TESS spa…

The spin-orbit alignment of visual binaries

A. B. Justesen, S. Albrecht

The angle between the stellar spin-axis and the orbital plane of a stellar or planetary companion has important implications for the formation and evolution of such systems. A stud…

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}^{+…

Evidence for Spin-orbit Alignment in the TRAPPIST-1 System

Teruyuki Hirano, Eric Gaidos, Joshua N. Winn +21

In an effort to measure the Rossiter-McLaughlin effect for the TRAPPIST-1 system, we performed high-resolution spectroscopy during transits of planets e, f, and b. The spectra were…

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…
