HR 6819 is a binary system with no black hole -- revisiting the source with infrared interferometry and optical integral field spectroscopy
A. J. Frost, J. Bodensteiner, Th. Rivinius +16
Two scenarios have been proposed to match the existing observational constraints of the object HR 6819. The system could consist of a close inner B-type giant plus a black hole (BH…
Spectroscopy of the massive interacting binary UU Cassiopeiae
P. Hadrava, M. Cabezas, G. Djurašević +9
Context. The eclipsing close binary UU Cas is an interacting massive double-periodic system with a gainer star partly hidden in an accretion disk. Aims. In order to study the physi…
Fundamental parameters of the eclipsing binary DD CMa and evidence for mass exchange
J. A. Rosales, R. E. Mennickent, G. Djurašević +5
We present a detailed photometric and spectroscopic analysis of DD CMa, based on published survey photometry and new spectroscopic data. We find an improved orbital period of $P_\m…
Gem: a hierarchical triple system with an outer Be star
Robert Klement, Petr Hadrava, Thomas Rivinius +17
Time series of spectroscopic, speckle-interferometric, and optical long-baseline-interferometric observations confirm that Gem is a hierarchical triple system. It consists of a…
New insights on the massive interacting binary UU Cassiopeiae
R. E. Mennickent, G. Djurašević, I. Vince +7
We present the results of the study of the close binary UU Cassiopeiae based on previously published multi wavelength photometric and spectroscopic data. Based on eclipse timings o…
On the long cycle variability of the Algol OGLE-LMC-DPV-065 and its stellar, orbital and disk parameters
R. E. Mennickent, M. Cabezas, G. Djurašević +13
OGLE-LMC-DPV-065 is an interacting binary whose double-hump long photometric cycle remains hitherto unexplained. We analyze photometric time series available in archive datasets sp…
