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 …

We review recent determinations of the present‐day mass function (PDMF) and initial mass
function (IMF) in various components of the Galaxy—disk, spheroid, young, and globular …

Precise and accurate parameters for late-type (late K and M) dwarf stars are important for
characterization of any orbiting planets, but such determinations have been hampered by …

We derive and parameterize the Galactic mass function (MF) below 1 M⊙ characteristic of
both single objects and binary systems. We resolve the long-standing discrepancy between …

Aims. We determine the radii and masses of 293 nearby, bright M dwarfs of the CARMENES
survey. This is the first time that such a large and homogeneous high-resolution (R> 80 000) …

Previous studies of planet occurrence rates largely relied on photometric stellar
characterizations. In this paper, we present planet occurrence rates for mid-type M dwarfs …

Asteroseismology provides us with a unique opportunity to improve our understanding of
stellar structure and evolution. Recent developments, including the first systematic studies of …

The availability of a number of new interferometric measurements of Main Sequence and
subgiant stars makes it possible to calibrate the surface brightness relations of these stars …

Here I review the current state of the field of optical stellar interferometry, concentrating on
ground-based work although a brief report of space interferometry missions is included. We …

Context. We examine the evolution of low-mass star and brown dwarf eclipsing binaries.
These objects are rapid rotators and are believed to shelter large magnetic fields. Aims. We …
