Duality refers to two equivalent descriptions of the same theory from different points of view.
Recently there has been tremendous progress in formulating and understanding possible …

Context. Gaia DR3 contains 1.8 billion sources with G-band photometry, 1.5 billion of which
with G BP and G RP photometry, complemented by positions on the sky, parallax, and …

We describe the simulated data sample for the Photometric Large Synoptic Survey
Telescope (LSST) Astronomical Time Series Classification Challenge (PLAsTiCC), a …

All-sky photometric time-series missions have allowed for the monitoring of thousands of
young (t age< 800 Myr) stars in order to understand the evolution of stellar activity. Here, we …

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 …

Context. Magnetic fields are a key component in the main sequence evolution of low mass
stars. Flares, energetic eruptions on the surfaces of stars, are an unmistakable manifestation …

Context. The ESA Gaia mission provides a unique time-domain survey for more than 1.6
billion sources with G≲ 21 mag. Aims. We showcase stellar variability in the Galactic colour …

Stars - IOPscience This site uses cookies. By continuing to use this site you agree to our use …

Solar-type stars exhibit their highest levels of magnetic activity during their early convective
pre-main-sequence (PMS) phase of evolution. The most powerful PMS flares, superflares …

We present a photometric characterization of 208 ultra-cool dwarfs (UCDs) with spectral
types between M4 and L4, from 20-s and 2-min cadence TESS light curves. We determine …
