TOI 1416 (BD+42 2504, HIP 70705) is a V=10 late G or early K-type dwarf star with transits detected by TESS. Radial velocities verify the presence of the transiting planet TOI-1416…

Kristine W. F. Lam, J. Cabrera, M. J. Hooton +83
We report the discovery of a third planet transiting the star TOI-1260, previously known to host two transiting sub-Neptune planets with orbital periods of 3.127 and 7.493 days, re…
TOI-2196 b: Rare planet in the hot Neptune desert transiting a G-type star
Carina M. Persson, Iskra Y. Georgieva, Davide Gandolfi +52
Highly irradiated planets in the hot Neptune desert are usually either small (R < 2 Rearth) and rocky or they are gas giants with radii of >1 Rjup. Here, we report on the intermedi…
A low-eccentricity migration pathway for a 13-h-period Earth analogue in a four-planet system
Luisa Maria Serrano, Davide Gandolfi, Alexander J. Mustill +47
It is commonly accepted that exoplanets with orbital periods shorter than 1 day, also known as ultra-short period (USP) planets, formed further out within their natal protoplanetar…
TOI-1268b: the youngest, hot, Saturn-mass transiting exoplanet
J. Šubjak, M. Endl, P. Chaturvedi +41
We report the discovery of TOI-1268b, a transiting Saturn-mass planet from the TESS space mission. With an age of less than one Gyr, derived from various age indicators, TOI-1268b…
GJ 367b: A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star
Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru +75
Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution p…
K2-99 revisited: a non-inflated warm Jupiter, and a temperate giant planet on a 522-d orbit around a subgiant
A. M. S. Smith, S. N. Breton, Sz. Csizmadia +29
We report new photometric and spectroscopic observations of the K2-99 planetary system. Asteroseismic analysis of the short-cadence light curve from K2's Campaign 17 allows us to r…
The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf
O. Barragán, D. J. Armstrong, D. Gandolfi +103
We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…
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…
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…
