The Penn State - Toruń Centre for Astronomy Planet Search stars IV. Dwarfs and the complete sample

B. Deka-Szymankiewicz, A. Niedzielski, M. Adamczyk +3

Our knowledge of the intrinsic parameters of exoplanets is as precise as our determinations of their stellar hosts parameters. In the case of radial velocity searches for planets,…

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)…
