Time-dependent properties of sunspot groups -- I. Lifetime and asymmetric evolution
Emese Forgács-Dajka, László Dobos, István Ballai
Aims. In this paper, we aim to study the time dependence of sunspot group areas in a large sample composed of various databases spanning over 130 years, used state-of-the-art stati…
TICs 167692429 and 220397947: The first compact hierarchical triple stars discovered with TESS
T. Borkovits, S. A. Rappaport, T. Hajdu +5
We report the discovery and complex analyses of the first two compact hierarchical triple star systems discovered with TESS in or near its southern continuous viewing zone during Y…
Eclipse timing variation analysis of OGLE-IV eclipsing binaries toward the Galactic Bulge. I. Hierarchical triple system candidates
T. Hajdu, T. Borkovits, E. Forgács-Dajka +3
We report a study of the eclipse timing variation (ETV) of short period () eclipsing binaries (EB) monitored during the photometric survey OGLE-IV. From the 425\,193 EB…
Rotation--differential rotation relationships for late-type single and binary stars from Doppler imaging
Zs. Kővári, K. Oláh, L. Kriskovics +3
From our sample of spotted late-type stars showing surface differential rotation we find that the relationship between the rotation period and the surface shear coefficient $α=ΔΩ/Ω…
A search for tight hierarchical triple systems amongst the eclipsing binaries in the CoRoT fields
T. Hajdu, T. Borkovits, E. Forgács-Dajka +5
We report a comprehensive search for hierarchical triple stellar system candidates amongst eclipsing binaries (EB) observed by the CoRoT spacecraft. We calculate and check eclipse…
Statistical relationship between the succeeding solar flares detected by the RHESSI satellite
L. G. Balázs, N. Gyenge, M. B. Korsós +3
The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) has observed more than 80,000 solar energetic events since its launch on February , 2002. Using this…
