Tracking Advanced Planetary Systems (TAPAS) with HARPS-N VIII. A wide-orbit planetary companion in the hot-Jupiter system HD 118203
G. Maciejewski, A. Niedzielski, K. Gozdziewski +5
The star HD 118203, classified as a K0 subgiant, was known to harbour a transiting hot Jupiter planet on a 6.1-day eccentric orbit. Previous studies also revealed a linear trend in…
Tracking Advanced Planetary Systems (TAPAS) with HARPS-N. VI. HD 238914 and TYC 3318-01333-1 - two more Li-rich giants with planets
M. Adamów, A. Niedzielski, K. Kowalik +4
We present the latest results of our search for planets with HARPS-N at the 3.6 m Telescopio Nazionale Galileo under the Tracking Advanced Planetary Systems project: an in-depth st…
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,…
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…
The Penn State - Toruń Centre for Astronomy Planet Search stars. III. The evolved stars sample
A. Niedzielski, B. Deka-Szymankiewicz, M. Adamczyk +3
We present basic atmospheric parameters (, , and [Fe/H]), rotation velocities and absolute radial velocities as well as luminosities, masses, ages and radii…
Tracking Advanced Planetary Systems with HARPS-N (TAPAS). I. A multiple planetary system around the red giant star TYC 1422-614-1
A. Niedzielski, E. Villaver, A. Wolszczan +7
Context. Stars that have evolved-off the Main Sequence are crucial in expanding the frontiers of knowledge on exoplanets toward higher stellar masses, and to constrain star-planet…
The Penn State - Torun Centre for Astronomy Planet Search stars. II. Lithium abundance analysis of the Red Giant Clump sample
M. Adamow, A. Niedzielski, E. Villaver +2
Using the sample of 348 stars from the PennState-Torun Centre for Astronomy Planet Search, for which uniformly determined atmospheric parameters are available, with chemical abunda…
Constraints on a second planet in the WASP-3 system
G. Maciejewski, A. Niedzielski, A. Wolszczan +30
There have been previous hints that the transiting planet WASP-3 b is accompanied by a second planet in a nearby orbit, based on small deviations from strict periodicity of the obs…
