TOI-4616 b: a benchmark Earth-sized planet transiting a nearby M4 dwarf

F. Zong Lang, B. O. Demory, Y. Gomez Maqueo Chew +44

Rocky exoplanets are particularly abundant around M-type stars. Their small radii and low luminosities provide favourable conditions for detecting transiting terrestrial planets an…

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…

Two temperate Earth- and Neptune-sized planets orbiting fully convective M dwarfs

Madison G. Scott, Georgina Dransfield, Mathilde Timmermans +30

As the diversity of exoplanets continues to grow, it is important to revisit assumptions about habitability and classical HZ definitions. In this work, we introduce an expanded 'te…

TOI-7166 b: A Habitable Zone mini-Neptune planet around a nearby low-mass star

Khalid Barkaoui, Francisco J. Pozuelos, Benjamin V. Rackham +41

We present the discovery and validation of TOI-7166b, a 2.01+/-0.05R_Earth planet orbiting a nearby low-mass star. We validated the planet by combining TESS and multi-color high-pr…

BEBOP VIII. SOPHIE radial velocities reveal an eccentric, circumbinary brown dwarf

Amaury H. M. J. Triaud, Thomas A. Baycroft, Neda Heidari +18

Circumbinary configurations offer a test of planet formation in an altered environment, where the inner binary has perturbed a protoplanetary disc. Comparisons of the physical and…

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.…

ATREIDES I. Embarking on a trek across the exo-Neptunian landscape with the TOI-421 system

V. Bourrier, M. Steiner, A. Castro-González +75

The distribution of close-in exoplanets is shaped by the interplay between atmospheric and dynamical processes. The Neptunian Desert, Ridge, and Savanna illustrate the sensitivity…

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…

BEBOP VII. SOPHIE discovery of BEBOP-3b, a circumbinary giant planet on an eccentric orbit

Thomas A. Baycroft, Alexandre Santerne, Amaury H. M. J. Triaud +21

Planetary systems orbiting close binaries are valuable testing grounds for planet formation and migration models. More detections with good mass measurements are needed. We present…

EBLM XV -- Revised dynamical masses for the circumbinary planet host Kepler-16 AB, using the SOPHIE spectrograph

D. Sebastian, I. Boisse, A. Santerne +14

Eclipsing binaries are perfect laboratories to measure precise, accurate and model-independent stellar radii and stellar masses, so long as both components are spectroscopically re…

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…

BEBOP VI. Enabling the detection of circumbinary planets orbiting double-lined binaries with the DOLBY method of radial-velocity extraction

Lalitha Sairam, Thomas A. Baycroft, Isabelle Boisse +13

Circumbinary planets - planets that orbit both stars in a binary system - offer the opportunity to study planet formation and orbital migration in a different environment compare t…

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…
