Estimating stellar metallicities from Gaia DR3 XP data using LAMOST DR10
Divyansh Srivastava, Andrzej Niedzielski, Rodolfo Smiljanic
Gaia DR3 provides astrophysical parameters for hundreds of millions of stars, but the metallicities [M/H] from its GSP-Phot module suffer from systematic biases. We estimate stella…
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…
Vision Transformer for Transient Noise Classification
Divyansh Srivastava, Andrzej Niedzielski
Transient noise (glitches) in LIGO data hinders the detection of gravitational waves (GW). The Gravity Spy project has categorized these noise events into various classes. With the…
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'…
UVSat: a concept of an ultraviolet/optical photometric satellite
A. Pigulski, A. Baran, M. Bzowski +25
Time-series photometry from space in the ultraviolet can be presently done with only a few platforms, none of which is able to provide wide-field long-term high-cadence photometry.…
On the GJ 436 planetary system
G. Maciejewski, A. Niedzielski, G. Nowak +4
The GJ 436 system contains a transiting planet GJ 436 b which is a hot analogue of Neptune on an eccentric orbit. Recently, two additional transiting sub-Earth planets have been po…
