TOI-4552 b: A new ultra-short period rocky world revealed by NIRPS and TESS
Avidaan Srivastava, René Doyon, François Bouchy +57
A particularly intriguing subclass of rocky exoplanets are the ultra-short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly rare a…
Hidden Gems in TESS: sherlock finds two new rocky planets around nearby M dwarfs
M. Timmermans, M. Dévora-Pajares, F. J. Pozuelos +25
The Hidden Gems project searches the TESS data for additional planets transiting low-mass stars in confirmed systems. Our goal is to identify planet candidates that are below the d…
MANGOS II: Five new giant planets orbiting low-mass stars
G. Dransfield, M. Timmermans, D. Sebastian +47
Giant planets orbiting low-mass stars on short orbits present a conundrum, as in the most extreme cases their existence cannot be reconciled with current models of core accretion.…
High five from ASTEP: Three validated planets and two eclipsing binaries in a diverse set of long-period candidates
Erika Rea, Maximilian N. Günther, George Dransfield +44
We present the analysis of five long-period TESS Objects of Interest (TOIs), all orbiting Sun-like stars, with orbital periods exceeding one month. Initially identified by the Tran…
A Cold and Super-Puffy Planet on a Prograde Orbit
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36
We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…
Two warm Earth-sized exoplanets and an Earth-sized candidate in the M5V-M6V binary system TOI-2267
S. Zúñiga-Fernández, F. J. Pozuelos, M. Dévora-Pajares +63
We report two warm Earth-sized exoplanets orbiting the close binary TOI-2267 (M5+M6, separation ~8 au). Data from TESS and ground-based facilities confirm the planets, but we canno…
TOI-2407 b: a warm Neptune in the desert
C. Janó Muñoz, M. J. Hooton, P. P. Pedersen +22
We present the validation of TOI-2407 b, a warm Neptune-sized planet with a radius of 4.26 0.26 R, orbiting an early M-type star with a period of 2.7 days and an equ…
A transiting rocky super-Earth and a non-transiting sub-Neptune orbiting the M dwarf TOI-771
G. Lacedelli, E. Pallé, Y. T. Davis +24
The origin and evolution of the sub-Neptune population is a highly debated topic in the exoplanet community. With the advent of JWST, atmospheric studies can now put unprecedented…
TOI-6508b: A massive transiting brown dwarf orbiting a low-mass star
K. Barkaoui, D. Sebastian, S. Zúñiga-Fernández +44
We report the discovery of a transiting brown dwarf orbiting a low-mass star, TOI-6508b. Today, only ~50 transiting brown dwarfs have been discovered. TOI-6508b was first detected…
TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet
K. Barkaoui, J. Korth, E. Gaidos +119
TOI-2015 is a known exoplanetary system around an M4 dwarf star, consisting of a transiting sub-Neptune planet in a 3.35-day orbital period, TOI-2015b, accompanied by a non-transit…
TOI 762 A b and TIC 46432937 b: Two Giant Planets Transiting M Dwarf Stars
Joel D. Hartman, Daniel Bayliss, Rafael Brahm +33
We present the discovery of TOI 762 A b and TIC 46432937 b, two giant planets transiting M dwarf stars. Transits of both systems were first detected from observations by the NASA T…
NGTS-28Ab: A short period transiting brown dwarf
Beth A. Henderson, Sarah L. Casewell, Michael R. Goad +43
We report the discovery of a brown dwarf orbiting a M1 host star. We first identified the brown dwarf within the Next Generation Transit Survey data, with supporting observations f…
TESS discovery of a super-Earth orbiting the M dwarf star TOI-1680
M. Ghachoui, A. Soubkiou, R. D. Wells +52
We report the discovery by the TESS mission of a super-Earth on a 4.8-d orbit around an inactive M4.5 dwarf (TOI-1680) validated by ground-based facilities. The host star is locate…
TOI-2084 b and TOI-4184 b: two new sub-Neptunes around M dwarf stars
K. Barkaoui, M. Timmermans, A. Soubkiou +67
We present the discovery and validation of two TESS exoplanets orbiting nearby M dwarfs: TOI-2084b, and TOI-4184b. We characterized the host stars by combining spectra from Shane/K…
ExoClock Project III: 450 new exoplanet ephemerides from ground and space observations
A. Kokori, A. Tsiaras, B. Edwards +214
The ExoClock project has been created with the aim of increasing the efficiency of the Ariel mission. It will achieve this by continuously monitoring and updating the ephemerides o…
TOI-2257 b: A highly eccentric long-period sub-Neptune transiting a nearby M dwarf
N. Schanche, F. J. Pozuelos, M. N. Günther +61
Thanks to the relative ease of finding and characterizing small planets around M dwarf stars, these objects have become cornerstones in the field of exoplanet studies. The current…
