Masses and luminosities for 342 stars from the PennState-Toruń Centre for Astronomy Planet Search
M. Adamczyk, B. Deka-Szymankiewicz, A. Niedzielski
We present revised basic stellar astrophysical parameters: masses, luminosities, ages and radii for 342 stars from PennState-Toruń Centre for Astronomy Planet Search. Atmospheric p…
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…
