On the apsidal motion of BP Vulpeculae
Sz. Csizmadia, E. Illes-Almar, T. Borkovits
BP Vulpeculae is a bright eclipsing binary system showing apsidal motion. It was found in an earlier study that it shows retrograde apsidal motion which contradicts theory. In this…
The Rapid Outbursting Star GM Cep: An EX-or in Tr 37?
Aurora Sicilia-Aguilar, Bruno Merin, Felix Hormuth +9
We present optical, IR and millimeter observations of the solar-type star 13-277, also known as GM Cep, in the 4 Myr-old cluster Tr 37. GM Cep experiences rapid magnitude variation…
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…
Physical parameters and multiplicity of five southern close eclipsing binaries
T. Szalai, L. L. Kiss, Sz. Meszaros +2
Aims: Detect tertiary components of close binaries from spectroscopy and light curve modelling; investigate light-travel time effect and the possibility of magnetic activity cycles…
A possible interrelation between the estimated luminosity distances and internal extinctions of type Ia supernovae
L. G. Balazs, Zs. Hetesi, Zs. Regaly +4
We studied the statistical properties of the luminosity distance and internal extinction data of type Ia supernovae in the lists published by Tonry et al. (2003) and Barris et al.…
Filling the Infrared Gap: ISO Observations of 1 Jy BL Lacertae Objects
P. Padovani, P. Giommi, P. Abraham +2
The large majority of BL Lacertae objects belonging to the 1 Jy sample, the class prototype for radio-selected sources, are thought to emit most of their synchrotron power in the f…
