The Penn State - Toruń Centre for Astronomy Planet Search stars. III. The evolved stars sample
A. Niedzielski, B. Deka-Szymankiewicz, M. Adamczyk +3
We present basic atmospheric parameters (, , and [Fe/H]), rotation velocities and absolute radial velocities as well as luminosities, masses, ages and radii…
TAPAS - Tracking Advanced Planetary Systems with HARPS-N. II. Super Li-rich giant HD 107028
M. Adamow, A. Niedzielski, E. Villaver +5
Lithium rich giant stars are rare objects. For some of them, Li enrichment exceeds abundance of this element found in solar system meteorites, suggesting that these stars have gone…
Three red giants with substellar-mass companions
A. Niedzielski, A. Wolszczan, G. Nowak +5
We present three giant stars from the ongoing Penn State-Toruń Planet Search with the Hobby-Eberly Telescope, which exhibit radial velocity variations that point to a presence of p…
On the GJ 436 planetary system
G. Maciejewski, A. Niedzielski, G. Nowak +4
The GJ 436 system contains a transiting planet GJ 436 b which is a hot analogue of Neptune on an eccentric orbit. Recently, two additional transiting sub-Earth planets have been po…
