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…
A terrestrial planet candidate in a temperate orbit around Proxima Centauri
Guillem Anglada-Escudé, Pedro J. Amado, John Barnes +28
At a distance of 1.295 parsecs, the red-dwarf Proxima Centauri ( Centauri C, GL 551, HIP 70890, or simply Proxima) is the Sun's closest stellar neighbor and one of the best stud…
Fast radio bursts: the observational case for a Galactic origin
Dan Maoz, Abraham Loeb, Yossi Shvartzvald +10
There are by now ten published detections of fast radio bursts (FRBs), single bright GHz-band millisecond pulses of unknown origin. Proposed explanations cover a broad range from e…
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…
Evolution of Cool Close Binaries -- Rapid Mass Transfer and Near Contact Binaries
Kazimierz Stepien, Marcin Kiraga
[Abridged] We test the evolutionary model of cool close binaries on the observed properties of near contact binaries (NCBs). Those with a more massive component filling the Roche l…
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…
ASAS photometry of ROSAT sources I. Periodic variable stars coincident with bright sources from ROSAT all sky survey
M. Kiraga
Photometric data from the ASAS - South (declination less than 29 deg) survey have been used for identification of bright stars located near the sources from the ROSAT All Sky Surve…
Age-Rotation-Activity Relations for M Dwarf Stars Based on ASAS Photometric Data
M. Kiraga, K. Stepien
Based on analysis of photometric observations of nearby M type stars obtained with ASAS, 31 periodic variables were detected. The determined periods are assumed to be related to ro…
Gaussianity of Cosmic Velocity Fields and Linearity of the Velocity-Gravity Relation
Pawel Ciecielag, Michal Chodorowski, Marcin Kiraga +3
We present a numerical study of the relation between the cosmic peculiar velocity field and the gravitational acceleration field. We show that on mildly non-linear scales (4-10 Mpc…
The Color--Magnitude Diagram in Baade's Window Revisited
M. Kiraga, B. Paczynski, K. Z. Stanek
We have reanalyzed the OGLE and photometry of stars in Baade's Window, and we confirm the extinction map published by Stanek (1996). However, we find that th…
