Evidence for LP 890-9d via Transit Timing Variations
Kevin B. Stevenson, Guangwei Fu, Kristin S. Sotzen +10
LP 890-9, also known as SPECULOOS-2 and TOI-4306, is a nearby late-M dwarf hosting two confirmed transiting rocky exoplanets. We analyze 20 JWST/NIRSpec PRISM transits of LP 890-9b…
Refined parameters, formation, and dynamical stability of the wild exoplanet system K2-312=HD 80653
L. Naponiello, E. Poretti, K. Rice +24
The architecture of planetary systems hosting ultra-short-period (USP) planets is a key diagnostic for understanding formation and migration scenarios. The presence of outer giant…
Constraining Small Planet Compositions for Future Missions
Larissa Palethorpe, Annelies Mortier, Jo Ann Egger +14
Accurate mass and radius measurements of small transiting exoplanets are essential for probing their compositions, formation histories, and potential habitability. We present a uni…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
Discovery and characterisation of two exoplanets orbiting the metal-poor, solar-type star TOI-5788 with TESS, CHEOPS, and HARPS-N
Ben S. Lakeland, A. Mortier, R. D. Haywood +48
We present the discovery and characterisation of two transiting exoplanets orbiting the metal-poor, solar-type star TOI-5788. From our analysis of six \textit{TESS} sectors and a d…
Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
HARPS-N, TESS, and CHEOPS discover a transiting sub-Neptune and two outer companions around the bright solar analogue HD 85426
F. Lienhard, A. Mortier, A. Collier Cameron +96
We provide a detailed characterisation of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (: 0.99 ; : 1.13 $\text{R…
A four-planet system orbiting the old thick disk star TOI-1203
D. Gandolfi, A. Alnajjarine, L. M. Serrano +120
TOI-1203 is a bright (V=8.6) G3 V star known to host a transiting warm sub-Neptune on a 25.5 d orbit. Here we report on an intensive high-precision radial velocity and photometric…
Discovery of a multi-planetary system orbiting the aged Sun-like star HD 224018
M. Damasso, L. Naponiello, A. Anna John +22
In 2016, Kepler/K2 detected a system of two sub-Neptunes transiting the star HD 224018, one of them showing a mono-transit event. In 2017, we began a spectroscopic follow-up with H…
The mass of the exo-Venus Gliese 12 b, as revealed by HARPS-N, ESPRESSO, and CARMENES
Daisy A. Turner, Yoshi Nike Emilia Eschen, Felipe Murgas +60
Small temperate planets are prime targets for exoplanet studies due to their possible similarities with the rocky planets in the Solar System. M dwarfs are promising hosts since th…
Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS and CHEOPS
Shishir Dholakia, Larissa Palethorpe, Alexander Venner +33
We report on the discovery of Gliese 12 b, the nearest transiting temperate, Earth-sized planet found to date. Gliese 12 is a bright ( mag, mag) metal-poor M4V star…
Confronting compositional confusion through the characterisation of the sub-Neptune orbiting HD 77946
L. Palethorpe, A. Anna John, A. Mortier +29
We report on the detailed characterization of the HD 77946 planetary system. HD 77946 is an F5 ( = 1.17 M, = 1.31 R) star, which hosts a transiting p…
