Planetary-mass companions to a retired B star BD+37 3172 and a retired F star BD+42 2315

Andrzej Niedzielski, Robert Jaros, Artur Paczuski +5

Radial velocity searches may lead to detection of exoplanets at large orbital separations only if long-enough time-series of data are available. Therefore publication of precise me…

Low-mass companions to nine stars

Andrzej Niedzielski, Robert Jaros, Divyansh Srivastava +5

We present an independent spectroscopic and radial velocity analysis for nine stars from the Pennsylvania-Toruń Planet Search. For BD+24 4697, we present an updated true companion'…

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…
