The CARMENES search for exoplanets around M dwarfs. Occurrence rates of Earth-like planets around very low-mass stars

A. Kaminski, S. Sabotta, J. Kemmer +24

Aims: Previous estimates of planet occurrence rates in the CARMENES survey indicated increased numbers of planets on short orbits for M dwarfs with masses below 0.34\,M. He…

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…

Exploring the atmosphere of GJ 1132 b with CRIRES+

E. Palle, F. Yan, G. Morello +8

With a mass, radius, and mean density similar to Earth's, the rocky planet GJ 1132 b is the first truly small planet for which an atmosphere detection was proposed. If confirmed, u…

TOI-512: Super-Earth transiting a K-type star discovered by TESS and ESPRESSO

J. Rodrigues, S. C. Barros, N. C. Santos +38

One of the goals of the ESPRESSO guaranteed time observations (GTOs) at the ESO 8.2m telescope is to follow up on candidate planets from transit surveys such as the TESS mission. H…

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…

A closer look at LTT 9779b: The ESPRESSO endeavour to pierce the atmospheric veil

R. Ramírez Reyes, James S. Jenkins, Elyar Sedaghati +9

The proliferation of exoplanet discoveries in exotic environments like the Neptune desert challenges our understanding of planetary atmospheres under intense irradiation. The unexp…
