Frequency of planets orbiting M dwarfs in the Solar neighbourhood
M. Tuomi, H. R. A. Jones, R. P. Butler +14
The most abundant stars in the Galaxy, M dwarfs, are very commonly hosts to diverse systems of low-mass planets. Their abundancy implies that the general occurrence rate of planets…
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…
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…
Model computations of blue stragglers and W UMa-type stars in globular clusters
Kazimierz Stepien, Marcin Kiraga
It was recently demonstrated that contact binaries occur in globular clusters (GCs) only immediately below turn-off point and in the region of blue straggler stars (BSs). In additi…
ASAS Photometry of ROSAT Sources. II.New Variables from the ASAS North Survey
M. Kiraga, K. Stepien
We present a catalog of 307 optical counterparts of the bright ROSAT X-ray sources, identified with the ASAS North survey data and showing periodic brightness variations. They all…
