The CARMENES search for exoplanets around M dwarfs : Understanding the wavelength dependence of radial velocity measurements

S. V. Jeffers, J. R. Barnes, P. Schöfer +22

Context. Current exoplanet surveys are focused on detecting small exoplanets orbiting in the liquid-water habitable zones of their host stars. Despite the recent significant advanc…

KOBE-1: The first planetary system from the KOBE survey. Two planets likely residing in the sub-Neptune mass regime around a late K-dwarf

O. Balsalobre-Ruza, J. Lillo-Box, A. M. Silva +35

K-dwarf stars are promising targets in the exploration of potentially habitable planets. Their properties, falling between G and M dwarfs, provide an optimal trade-off between the…

CAVITY, Calar Alto Void Integral-field Treasury surveY and project extension

I. Pérez, S. Verley, L. Sánchez-Menguiano +58

We have learnt in the last decades that the majority of galaxies belong to high density regions interconnected in a sponge-like fashion. This large-scale structure is characterised…

The KOBE experiment: K-dwarfs Orbited By habitable Exoplanets. Project goals, target selection and stellar characterization

J. Lillo-Box, N. C. Santos, A. Santerne +33

The detection of habitable worlds is one of humanity's greatest endeavors. So far, astrobiological studies show that one of the most critical components for life development is liq…

A giant exoplanet orbiting a very low-mass star challenges planet formation models

J. C. Morales, A. J. Mustill, I. Ribas +179

Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…

The CARMENES search for exoplanets around M dwarfs. Two temperate Earth-mass planet candidates around Teegarden's Star

M. Zechmeister, S. Dreizler, I. Ribas +182

Context. Teegarden's Star is the brightest and one of the nearest ultra-cool dwarfs in the solar neighbourhood. For its late spectral type (M7.0V), the star shows relatively little…

High-resolution confirmation of an extended helium atmosphere around WASP-107b

R. Allart, V. Bourrier, C. Lovis +7

Probing the evaporation of exoplanet atmospheres is key to understanding the formation and evolution of exoplanetary systems. The main tracer of evaporation in the UV is the Lyman-…

The CARMENES search for exoplanets around M dwarfs. First visual-channel radial-velocity measurements and orbital parameter updates of seven M-dwarf planetary systems

T. Trifonov, M. Kürster, M. Zechmeister +166

Context: The main goal of the CARMENES survey is to find Earth-mass planets around nearby M-dwarf stars. Seven M-dwarfs included in the CARMENES sample had been observed before wit…
