Stellar activity analysis of Barnard's Star: Very slow rotation and evidence for long-term activity cycle

B. Toledo-Padrón, J. I. González Hernández, C. Rodríguez-López +58

The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of…

A candidate super-Earth planet orbiting near the snow line of Barnard's star

I. Ribas, M. Tuomi, A. Reiners +60

At a distance of 1.8 parsecs, Barnard's star (Gl 699) is a red dwarf with the largest apparent motion of any known stellar object. It is the closest single star to the Sun, second…

Prospects for detecting the astrometric signature of Barnard's Star b

Lev Tal-Or, Shay Zucker, Ignasi Ribas +2

A low-amplitude periodic signal in the radial velocity (RV) time series of Barnard's Star was recently attributed to a planetary companion with a minimum mass of 3.2 $M_\op…

The CARMENES search for exoplanets around M dwarfs: A low-mass planet in the temperate zone of the nearby K2-18

Paula Sarkis, Thomas Henning, Martin Kürster +22

K2-18 is a nearby M2.5 dwarf, located at 34 pc and hosting a transiting planet which was first discovered by the {\it K2} mission and later confirmed with {\it Spitzer Space Telesc…

AD Leonis: Radial velocity signal of stellar rotation or spin-orbit resonance?

Mikko Tuomi, Hugh R. A. Jones, Guillem Anglada-Escudé +3

AD Leonis is a nearby magnetically active M dwarf. We find Doppler variability with a period of 2.23 days as well as photometric signals: (1) a short period signal which is similar…
