The angular momentum (AM) evolution of stellar interiors, along with the resulting rotation
rates of stellar remnants, remains poorly understood. Asteroseismic measurements of red …

Aims. We study the evolution of the rotation and the high energy X-ray, extreme ultraviolet
(EUV), and Ly-α emission for F, G, K, and M dwarfs, with masses between 0.1 and 1.2 M⊙ …

Though distant and seemingly unreachable, planets outside the Solar System, or
exoplanets, have captivated the imagination of scientists and stargazers alike. With more …

M dwarfs dominate the stellar population, accounting for three of every four stars, the nearest
of which is Proxima Centauri, the closest destination beyond our Solar System. These cool …

We present a new age-dating technique that combines gyrochronology with isochrone fitting
to infer ages for FGKM main-sequence and subgiant field stars. Gyrochronology and …

Context. The Gaia Data Release 2 (DR2) contains more than half a million sources that are
identified as variable stars. Aims. We summarise the processing and results of the …

A Temporary Epoch of Stalled Spin-down for Low-mass Stars: Insights from NGC 6811 with
Gaia and Kepler - IOPscience This site uses cookies. By continuing to use this site you agree …

We present a study of flare rates, rotation periods, and spectroscopic activity indicators of
125 single stars within 15 parsecs and with masses between 0.1 and 0.3 M⊙ observed …

Solar-like stars (M≲ 1.3 M⊙) lose angular momentum through their magnetized winds. The
resulting evolution of the surface rotation period, which can be directly measured …

Exoplanets can evolve significantly between birth and maturity, as their atmospheres, orbits,
and structures are shaped by their environment. Young planets (< 1 Gyr) offer an opportunity …
