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…
A Transiting Giant on a 7.7-Year Orbit Revealed by TTVs in the TOI-201 System
Gracjan Maciejewski, Weronika Łoboda
We report the detection and characterization of TOI-201 c, a long-period transiting companion to the warm Jupiter TOI-201 b. Its presence was first inferred from high-amplitude tra…
New transit timing observations for GJ 436 b, HAT-P-3 b, HAT-P-19 b, WASP-3 b, and XO-2 b
G. Maciejewski, M. Stangret, J. Ohlert +4
We present new transit observations acquired between 2014 and 2018 for the hot exoplanets GJ 436 b, HAT-P-3 b, HAT-P-19 b, WASP-3 b, and XO-2 b. New mid-transit times extend the ti…
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.…
Three red giants with substellar-mass companions
A. Niedzielski, A. Wolszczan, G. Nowak +5
We present three giant stars from the ongoing Penn State-Toruń Planet Search with the Hobby-Eberly Telescope, which exhibit radial velocity variations that point to a presence of p…
Transit timing of TrES-2: a combined analysis of ground- and space-based photometry
St. Raetz, G. Maciejewski, Ch. Ginski +21
Homogeneous observations and careful analysis of transit light curves can lead to the identification of transit timing variations (TTVs). TrES-2 is one of few exoplanets, which off…
Revisiting parameters for the WASP-1 planetary system
G. Maciejewski, J. Ohlert, D. Dimitrov +8
We present thirteen new transit light curves for the WASP-1 b exoplanet. Observations were acquired with 0.5 - 1.2-m telescopes between 2007 and 2013. Our homogeneous analysis, whi…
The young open cluster Trumpler 3
G. Maciejewski, L. Bukowiecki
We present a photometric and spectroscopic study of the poorly investigated open cluster Trumpler~3. Basic parameters such as the age of Myr, the color excess $E(B-V)=0.3…
