Planets Around the K-Giants BD+20 274 and HD 219415
S. Gettel, A. Wolszczan, A. Niedzielski +4
We present the discovery of planet-mass companions to two giant stars by the ongoing Penn State- Toruń Planet Search (PTPS) conducted with the 9.2 m Hobby-Eberly Telescope. The les…
The Penn State-Torun Centre for Astronomy Planet Search stars. I. Spectroscopic analysis of 348 red giants
P. Zielinski, A. Niedzielski, A. Wolszczan +2
We present basic atmospheric parameters (Teff, logg, vt and [Fe/H]) as well as luminosities, masses, radii and absolute radial velocities for 348 stars, presumably giants, from the…
BD+48 740 - Li overabundant giant star with a planet. A case of recent engulfment?
M. Adamów, A. Niedzielski, E. Villaver +2
We report the discovery of a unique object, BD+48 740, a lithium overabundant giant with A(Li)=2.33 +/- 0.04 (where A(Li) = log(n_Li/n_H) + 12), that exhibits radial velocity (RV)…
