CARMENES input catalogue of M dwarfs IX. Multiplicity from close spectroscopic binaries to ultra-wide systems

C. Cifuentes, J. A. Caballero, J. González-Payo +12

Multiplicity studies greatly benefit from focusing on M dwarfs because they are often paired in a variety of configurations with both stellar and substellar objects, including exop…

The cool brown dwarf Gliese 229 B is a close binary

Jerry W. Xuan, A. Mérand, W. Thompson +76

Owing to their similarities with giant exoplanets, brown dwarf companions of stars provide insights into the fundamental processes of planet formation and evolution. From their orb…

The Gaia Ultracool Dwarf Sample -- IV. GTC/OSIRIS optical spectra of Gaia late-M and L dwarfs

W. J. Cooper, H. R. A. Jones, R. L. Smart +20

As part of our comprehensive, ongoing characterisation of the low-mass end of the main sequence in the Solar neighbourhood, we used the OSIRIS instrument at the 10.4 m Gran Telesco…

TESS discovery of two super-Earths orbiting the M-dwarf stars TOI-6002 and TOI-5713 near the radius valley

M. Ghachoui, B. V. Rackham, M. Dévora-Pajares +45

We present the validation of two TESS super-Earth candidates transiting the mid-M dwarfs TOI-6002 and TOI-5713 every 10.90 and 10.44 days, respectively. The first star (TOI-6002) i…

JWST imaging of the closest globular clusters -- IV. Chemistry, luminosity, and mass functions of the lowest-mass members in the NIRISS parallel fields

M. Libralato, R. Gerasimov, L. Bedin +9

We present observations of the two closest globular clusters, NGC 6121 and NGC 6397, taken with the NIRISS detector of JWST. The combination of our new JWST data with archival Hubb…

The HST Large Programme on Omega Centauri -- VII. The white dwarf cooling sequence

M. Scalco, M. Salaris, L. Bedin +9

We present a study of the white dwarf (WD) cooling sequence (CS) in the globular cluster (GC) Omega Centauri, the primary goal of a dedicated Hubble Space Telescope (HST) programme…

Three short-period Earth-sized planets around M dwarfs discovered by TESS: TOI-5720b, TOI-6008b and TOI-6086b

K. Barkaoui, R. P. Schwarz, N. Narita +53

One of the main goals of the NASA's TESS (Transiting Exoplanet Survey Satellite) mission is the discovery of Earth-like planets around nearby M-dwarf stars. Here, we present the di…

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…

HST astrometry of the closest Brown Dwarfs -- II. Improved parameters and constraints on a third body

L. R. Bedin, J. Dietrich, A. J. Burgasser +5

Located at less than 2pc away, Luhman16AB (WISE.J104915.57-531906.1) is the closest pair of brown dwarfs and third closest `stellar' system to Earth. An exoplanet candidate in the…

The Large Programme on NGC6752 -- V. Differences in Luminosity and Mass Functions among Multiple Stellar Populations

M. Scalco, R. Gerasimov, L. R. Bedin +8

We exploit the astro-photometric dataset of the multi-epoch infrared parallel field of a Large Programme aimed at studying the faintest stars of t…
