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 …

Stellar dynamos generate magnetic fields that are of fundamental importance to the
variability and evolution of Sun-like and low-mass stars, and for the development of their …

Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime
interest to understand the physical and chemical conditions under which planet formation …

The mass–luminosity relation for late-type stars has long been a critical tool for estimating
stellar masses. However, there is growing need for both a higher-precision relation and a …

Context. The CARMENES survey is a high-precision radial velocity (RV) programme that
aims to detect Earth-like planets orbiting low-mass stars. Aims. We develop least-squares …

We present the first part of our Disks ARound T Tauri Stars with SPHERE (DARTTS-S)
survey: observations of eight T Tauri stars that were selected based on their strong (sub) …

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

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

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 …
