Joint Observations of PTPS Targets (JOTA). Combined spectroscopic and photometric analysis of 16 SB1 systems
Robert Jaros, Andrzje Niedzielski, Sohaib Ali +9
Context. The Pennsylvania-Toruń Planet Search, which operates on a sample of 1000 northern-hemisphere stars, has been underway since 2004. Stars with radial velocity (RV) amp…
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'…
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 VII. Elder suns with low-mass companions
Andrzej T. Niedzielski, Eva Villaver, Monika Adamów +3
We present the current status of and new results from our search for exoplanets in a sample of solar-mass, evolved stars observed with the HARPS-N and the 3.6-m Telescopio Nazional…
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,…
