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…

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…

An apparently eccentric orbit of the exoplanet WASP-12 b as a radial velocity signature of planetary-induced tides in the host star

Gracjan Maciejewski, Andrzej Niedzielski, Eva Villaver +2

Massive exoplanets on extremely tight orbits, such as WASP-12 b, induce equilibrium tides in their host stars. Following the orbital motion of the planet, the tidal fluid flow in t…

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…

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…

Observing the PTPS Sample of Evolved Exoplanet Host Candidates Using the NPOI

Ellyn K. Baines, J. Thomas Armstrong, Henrique R. Schmitt +6

We plan to measure the angular diameters of a sample of Penn State-Torun Planet Search (PTPS) giant exoplanet host star candidates using the Navy Precision Optical Interferometer.…
