HD 181068: A Red Giant in a Triply-Eclipsing Compact Hierarchical Triple System
A. Derekas, L. L. Kiss, T. Borkovits +41
Hierarchical triple systems comprise a close binary and a more distant component. They are important for testing theories of star formation and of stellar evolution in the presence…
EM Cygni: a study of its eclipse timings
Sz. Csizmadia, Zs. Nagy, T. Borkovits +3
EM Cygni is a Z Cam-subtype eclipsing dwarf nova. Its orbital period variations were reported in the past but the results were in conflict to each other while other studies allowed…
Tidal and rotational effects in the perturbations of hierarchical triple stellar systems. II. Eccentric systems - the case of AS Camelopardalis
T. Borkovits, E. Forgács-Dajka, Zs. Regály
We study the perturbations of a relatively close third star on a tidally distorted eccentric eclipsing binary. We consider both the observational consequences of the variations of…
Long-term variation in distribution of sunspot groups
E. Forgacs-Dajka, B. Major, T. Borkovits
We studied the relation between the distribution of sunspot groups and the Gleissberg cycle. As the magnetic field is related to the area of the sunspot groups, we used area-weight…
