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'…
A DECADE of dwarfs: first detection of weak lensing around spectroscopically confirmed low-mass galaxies
Chun-Hao To, Chihway Chang, Dhayaa Anbajagane +35
We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECA…
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…
Is there a metallicity enhancement in planet hosting red giants?
Pawel Zieliński, Andrzej Niedzielski, Monika Adamów +1
The Penn State/Toruń Centre for Astronomy Search for Planets Around Evolved Stars is a high-precision radial velocity (RV) survey aiming at planets detection around giant stars. It…
A Search for Planets with SALT
Monika Adamów, Andrzej Niedzielski
As the SALT High Resolution Spectrograph completion is nearing we plan to extend the Pennsylvania-Torun Planets Search (PTPS) with HET to the southern hemisphere. Due to overlap of…
