TESS and CHEOPS Discover Two Warm Sub-Neptunes Transiting the Bright K-dwarf HD 15906
Amy Tuson, Didier Queloz, Hugh P. Osborn +119
We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Sur…
Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops
Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126
HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …
First release of PLATO consortium stellar limb-darkening coefficients
Giuseppe Morello, Jeffrey Gerber, Bertrand Plez +4
We release the first grid of stellar limb-darkening coefficients (LDCs) and intensity profiles (IPs) computed by the consortium of the PLAnetary Transits and Oscillations of stars…
TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf
Faith Hawthorn, Daniel Bayliss, Thomas G. Wilson +137
We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright ( mag), high proper motion…
Reflectivity of Venus' dayside disk during the 2020 observation campaign: outcomes and future perspectives
Yeon Joo Lee, Antonio García Muñoz, Atsushi Yamazaki +28
We performed a unique Venus observation campaign to measure the disk brightness of Venus over a broad range of wavelengths in August and September 2020. The primary goal of the cam…
HD 28109 hosts a trio of transiting Neptunian planets including a near-resonant pair, confirmed by ASTEP from Antarctica
Georgina Dransfield, Amaury H. M. J. Triaud, Tristan Guillot +28
We report on the discovery and characterisation of three planets orbiting the F8 star HD~28109, which sits comfortably in \tess's continuous viewing zone. The two outer planets hav…
Uncovering the true periods of the young sub-Neptunes orbiting TOI-2076
Hugh P. Osborn, Andrea Bonfanti, Davide Gandolfi +93
Context: TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G = 8.9 mag), young ( Myr) K-type star. Although a validated planetary system, th…
A Radial Velocity Study of the Planetary System of Pi Mensae: Improved Planet Parameters for PI Mensae c and a Third Planet on a 125-d Orbit
Artie P. Hatzes, Davide Gandolfi, Judith Korth +33
Pi Men hosts a transiting planet detected by the TESS space mission and an outer planet in a 5.7-yr orbit discovered by RV surveys. We studied this system using new radial velocity…
A pair of Sub-Neptunes transiting the bright K-dwarf TOI-1064 characterised with CHEOPS
Thomas G. Wilson, Elisa Goffo, Yann Alibert +132
We report the discovery and characterisation of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in TESS photometry. To characterise…
Orbital Period Refinement of CoRoT Planets with TESS Observations
Peter Klagyivik, Hans J. Deeg, Szilard Csizmadia +2
CoRoT was the first space mission dedicated to exoplanet detection. Operational between 2007 and 2012, this mission discovered 37 transiting planets, including CoRoT-7b, the first…
A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776
