The Three body system delta Circini
P. Mayer, P. Harmanec, H. Sana +1
Delta Cir is known as an O7.5 III eclipsing and spectroscopic binary with an eccentric orbit. Penny et al. discovered the presence of a third component in the IUE spectra. The ecli…
HD 152246 - a new high-mass triple system and its basic properties
A. Nasseri, R. Chini, P. Harmanec +6
Analyses of multi-epoch, high-resolution (R ~ 50.000) optical spectra of the O-type star HD 152246 (O9 IV according to the most recent classification), complemented by a limited nu…
New and revised parameters for several southern OB binaries
Pavel Mayer, Horst Drechsel, Andreas Irrgang
Using ESO FEROS archive spectra of several southern OB-type binaries, we derived periods for three SB2 spectroscopic binaries, HD 97166, HD 115455, and HD 123590, and two SB1 syste…
Revised physical elements of the astrophysically important O9.5+O9.5V eclipsing binary system Y Cyg
P. Harmanec, D. E. Holmgren, M. Wolf +11
Thanks to its long and rich observational history and rapid apsidal motion, the massive eclipsing binary Y Cyg represents one of the cornestones to critical tests of stellar evolut…
