A comprehensive search for hot subdwarf stars using Gaia and TESS I. Pulsating hot subdwarf B stars
Murat Uzundag, Jurek Krzesinski, Ingrid Pelisoli +4
Hot subdwarf B (sdB) stars are evolved, subluminous, helium-burning stars, most likely formed when red-giant stars lose their hydrogen envelope via interactions with close companio…
Possible Gravitational Microlensing Events in the Optical Lightcurve of Active Galaxy S5 0716+714
D. Ł. Król, Ł. Stawarz, J. Krzesinski +1
A well-known active galaxy of the blazar type, S5 0716+714, is characterized by a particularly high variability duty cycle on short-time scales at optical frequencies. As such, the…
Discovery of new TESS pulsating hot subdwarfs
J. Krzesinski, L. A. Balona
This work is dedicated to a search for new pulsating hot subdwarfs in TESS photometric data which could have been missed in previous searches. By matching catalogues of hot subdwar…
The quest for planets around subdwarfs and white dwarfs from Kepler space telescope fields: Part I. Techniques and tests of the methods
J. Krzesinski, A. Blokesz, M. Siwak +1
In this study, we independently test the presence of an exoplanet around the binary KIC 9472174, which is composed of a red dwarf and a pulsating type B subdwarf. We also present t…
X-ray, UV and optical time delays in the bright Seyfert galaxy Ark 120 with co-ordinated Swift and ground-based observations
A. P. Lobban, S. Zola, U. Pajdosz-Smierciak +17
We report on the results of a multiwavelength monitoring campaign of the bright, nearby Seyfert galaxy, Ark 120 using a ~50-day observing programme with Swift and a ~4-month co-ord…
Analysis of putative exoplanetary signatures found in light curves of two sdBV stars observed by Kepler
A. Blokesz, J. Krzesinski, L. Kedziora-Chudczer
. We investigate the validity of the claim that invokes two extreme exoplanetary system candidates around the pulsating B-type subdwarfs KIC 10001893 and KIC 5807616…
