Abstract The Second Workshop on Extreme Precision Radial Velocities defined circa 2015
the state of the art Doppler precision and identified the critical path challenges for reaching …

Magnetic fields play a fundamental role for interior and atmospheric properties of M dwarfs
and greatly influence terrestrial planets orbiting in the habitable zones of these low-mass …

Context. Proxima Centauri is the closest star to the Sun. This small, low-mass, mid M dwarf is
known to host an Earth-mass exoplanet with an orbital period of 11.2 days within the …

Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation,
and these losses can affect their physical and chemical evolution. Studies of atmospheric …

This paper presents an overview of SPIRou, the new-generation near-infrared
spectropolarimeter/precision velocimeter recently installed on the 3.6-m Canada–France …

The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any
orbiting planets. In this paper, we present the survey sample by publishing one CARMENES …

The present-day envelope of gaseous planets is a relic of how these giant planets originated
and evolved. Measuring their elemental composition therefore presents a powerful …

Precise measurements of chemical abundances in planetary atmospheres are necessary to
constrain the formation histories of exoplanets. A recent study of WASP-127 b, a close-in …

Context. CARMENES is a stabilised, high-resolution, double-channel spectrograph at the
3.5 m Calar Alto telescope. It is optimally designed for radial-velocity surveys of M dwarfs …

The prospects for the habitability of M-dwarf planets have long been debated, due to key
differences between the unique stellar and planetary environments around these low-mass …
