The mass of a star is the most fundamental parameter for its structure, evolution, and final
fate. It is particularly important for any kind of stellar archaeology and characterization of …

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) …

We present the results of a stellar membership survey of the nearby open clusters Praesepe
and Coma Berenices. We have combined archival survey data from the SDSS, 2MASS …

The recent increase in the number of radius measurements of very low mass stars from
eclipsing binaries and interferometry of single stars has raised more questions about what …

The fundamental properties of low-mass stars are not as well understood as those of their
more massive counterparts. The best method for constraining these properties, especially …

ABSTRACT M dwarfs are prime targets in the hunt for habitable worlds around other stars.
This is due to their abundance as well as their small radii and low masses and temperatures …

We have found a new low-mass, double-lined, detached eclipsing binary, GU Boo, among a
sample of new variables from the ROTSE-I database. The binary has an orbital period of …

Using light curves from the HATNet survey for transiting extrasolar planets we investigate the
optical broadband photometric variability of a sample of 27, 560 field K and M dwarfs …

We have measured the angular diameters of six M dwarfs with the CHARA Array, a long-
baseline optical interferometer located at Mount Wilson Observatory. Spectral types range …

Eclipsing binaries with M-type components are still rare objects. Strong observational biases
have made that today only a few eclipsing binaries with component masses below 0.6 M⊙ …
