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'…
Investigating the Impact of Metallicity on Star Formation in the Outer Galaxy. I. VLT/KMOS Survey of Young Stellar Objects in Canis Major
Dominika Itrich, Agata Karska, Marta Sewiło +9
The effects of metallicity on the evolution of protoplanetary disks may be studied in the outer Galaxy where the metallicity is lower than in the solar neighbourhood. We present th…
Tracking Advanced Planetary Systems (TAPAS) with HARPS-N. V.: A Massive Jupiter orbiting the very low metallicity giant star BD+03 2562 and a possible planet around HD~103485
E. Villaver, A. Niedzielski, A. Wolszczan +6
We present two evolved stars from the TAPAS (Tracking Advanced PlAnetary Systems) with HARPS-N project devoted to RV precision measurements of identified candidates within the Penn…
TAPAS IV. TYC 3667-1280-1 b - the most massive red giant star hosting a warm Jupiter
A. Niedzielski, E. Villaver, G. Nowak +6
We present the latest result of the TAPAS project that is devoted to intense monitoring of planetary candidates that are identified within the PennState-Toruń planet search. We aim…
Tracking Advanced Planetary Systems (TAPAS) with HARPS-N. III. HD 5583 and BD+15 2375 - two cool giants with warm companions
A. Niedzielski, E. Villaver, G. Nowak +6
Evolved stars are crucial pieces to understand the dependency of the planet formation mechanism on the stellar mass and to explore deeper the mechanism involved in star-planet inte…
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…
