▪ Abstract Observational studies of low-mass stars during their early stages of evolution, from
protostars through the zero-age main sequence, show highly elevated levels of magnetic …

X-ray emission from stars in the cool half of the Hertzsprung-Russell diagram is generally
attributed to the presence of a magnetic corona that contains plasma at temperatures …

We present the ROSAT All-Sky Survey Bright Source Catalogue (RASS-BSC, revision
1RXS) derived from the all-sky survey performed during the first half year (1990/91) of the …

Current theories of planetary evolution predict that infant giant planets have large radii and
very low densities before they slowly contract to reach their final size after about several …

Young stellar associations hold a star formation record that can persist for millions of years,
revealing the progression of star formation long after the dispersal of the natal cloud. To …

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 …

Abstract The Taurus-Auriga complex is the prototypical low-mass star-forming region, and
provides a unique testbed of the star formation process, which left observable imprints on …

We show how molecular clouds in the solar neighborhood might be formed and produce
stars rapidly enough to explain stellar population ages, building on results from numerical …

We have analyzed nearly all images of the Taurus star-forming region at 3.6, 4.5, 5.8, 8.0,
and 24 μm that were obtained during the cryogenic mission of the Spitzer Space Telescope …

The high-precision astrometry from the second data release of the Gaia mission has made it
possible to greatly improve the census of members of nearby clusters and associations. I …
