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. 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 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…
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…
Planets Around the K-Giants BD+20 274 and HD 219415
S. Gettel, A. Wolszczan, A. Niedzielski +4
We present the discovery of planet-mass companions to two giant stars by the ongoing Penn State- Toruń Planet Search (PTPS) conducted with the 9.2 m Hobby-Eberly Telescope. The les…
The Penn State-Torun Centre for Astronomy Planet Search stars. I. Spectroscopic analysis of 348 red giants
P. Zielinski, A. Niedzielski, A. Wolszczan +2
We present basic atmospheric parameters (Teff, logg, vt and [Fe/H]) as well as luminosities, masses, radii and absolute radial velocities for 348 stars, presumably giants, from the…
Substellar-Mass Companions to the K-Giants HD 240237, BD +48 738 and HD 96127
S. Gettel, A. Wolszczan, A. Niedzielski +4
We present the discovery of substellar-mass companions to three giant stars by the ongoing Penn State-Toruń Planet Search (PTPS) conducted with the 9.2 m Hobby-Eberly Telescope. Th…
