Infrared photometry with InGaAs detectors: First light with SPECULOOS
Peter P. Pedersen, Didier Queloz, Lionel Garcia +15
We present the photometric performance of SPIRIT, a ground-based near-infrared InGaAs CMOS-based instrument (1280 by 1024 pixels, 12 micron pitch), using on-sky results from the SP…
TOI-2379 b and TOI-2384 b: two super-Jupiter mass planets transiting low-mass host stars
Edward M. Bryant, Daniel Bayliss, Joel D. Hartman +31
Short-period gas giant planets have been shown to be significantly rarer for host stars less massive than the Sun. We report the discovery of two transiting giant planets - TOI-237…
BEBOP V. Homogeneous Stellar Analysis of Potential Circumbinary Planet Hosts
Alix V. Freckelton, Daniel Sebastian, Annelies Mortier +29
Planets orbiting binary systems are relatively unexplored compared to those around single stars. Detections of circumbinary planets and planetary systems offer a first detailed vie…
CHEOPS in-flight performance: A comprehensive look at the first 3.5 years of operations
A. Fortier, A. E. Simon, C. Broeg +128
CHEOPS is a space telescope specifically designed to monitor transiting exoplanets orbiting bright stars. In September 2023, CHEOPS completed its nominal mission and remains in exc…
Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3
Michaël Gillon, Peter P. Pedersen, Benjamin V. Rackham +81
Located at the bottom of the main sequence, ultracool dwarf stars are widespread in the solar neighbourhood. Nevertheless, their extremely low luminosity has left their planetary p…
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…
TOI-4336 A b: A temperate sub-Neptune ripe for atmospheric characterization in a nearby triple M-dwarf system
M. Timmermans, G. Dransfield, M. Gillon +54
Small planets transiting bright nearby stars are essential to our understanding of the formation and evolution of exoplanetary systems. However, few constitute prime targets for at…
A long-period transiting substellar companion in the super-Jupiters to brown dwarfs mass regime and a prototypical warm-Jupiter detected by TESS
Matias I. Jones, Yared Reinarz, Rafael Brahm +48
We report on the confirmation and follow-up characterization of two long-period transiting substellar companions on low-eccentricity orbits around TIC 4672985 and TOI-2529, whose t…
Evidence for transit-timing variations of the 11 Myr exoplanet TOI-1227 b
J. M. Almenara, X. Bonfils, T. Guillot +27
TOI-1227 b is an 11 Myr old validated transiting planet in the middle of its contraction phase, with a current radius of 0.85 R. It orbits a low-mass pre-main sequence star (0.…
