RV and LC of 8 M dwarf stars with planets
Exoplanets smaller than Neptune are common around red dwarf stars (M dwarfs), with those that transit their host star constituting the bulk of known temperate worlds amenable... -
Light curves and radial velocities for TOI-1899
TOI-1899b is a rare exoplanet, a temperate warm Jupiter orbiting an M-dwarf, first discovered by Canas et al. (2020) from a TESS single-transit event. Using new radial... -
M dwarfs in the Pleiades
Rotation periods obtained with the Kepler satellite have been combined with precise measurements of projected rotation velocity from the WIYN 3.5-m telescope to determine the... -
Chromospheric emissions of 177 M dwarfs
The chromospheric emission estimated in the core of different lines, such as CaII H & K, Na D1 and D2, and Ha, is not always correlated between lines. In particular, the... -
R-band LC and spectrum of a superstellar flare
We report the detection and follow-up of a superstellar flare GWAC181229A with an amplitude of {Delta}R~9.5mag on an M9-type star by SVOM/GWAC and the dedicated follow-up... -
Rotation periods for 261 M dwarfs
Knowledge of rotation periods (Prot) is important for understanding the magnetic activity and angular momentum evolution of late-type stars, as well as for evaluating radial... -
IGRINS III. Abundances of 50 M giants
In order to be able to investigate the chemical history of the entire MilkyWay, it is imperative to also study the dust-obscured regions, where most of the mass lies, in detail....
