Activity cycles in members of young loose stellar associations
E. Distefano, A. C. Lanzafame, A. Lanza +2
Magnetic cycles have been detected in tens of solar-like stars. The relationship between the cycle properties and global stellar parameters is not fully understood yet. We searched…
Lithium abundance and 6Li/7Li ratio in the active giant HD123351 I. A comparative analysis of 3D and 1D NLTE line-profile fits
A. Mott, M. Steffen, E. Caffau +2
Current three-dimensional (3D) hydrodynamical model atmospheres together with NLTE spectrum synthesis, permit to derive reliable atomic and isotopic chemical abundances from high-r…
The Sirius System and its Astrophysical Puzzles: Hubble Space Telescope and Ground-Based Astrometry
Howard E. Bond, Gail H. Schaefer, Ronald L. Gilliland +11
Sirius, the seventh-nearest stellar system, is a visual binary containing the metallic-line A1 V star Sirius A, brightest star in the sky, orbited in a 50.13-year period by Sirius…
The Yale-Potsdam Stellar Isochrones (YaPSI)
F. Spada, P. Demarque, Y. -C. Kim +2
We introduce the Yale-Potsdam Stellar Isochrones (YaPSI), a new grid of stellar evolution tracks and isochrones of solar-scaled composition. In an effort to improve the Yonsei-Yale…
