Towards a consistent model of the hot quadruple system HD 93206 = QZ Carinæ: II. N-body model
M. Brož, P. Harmanec, P. Zasche +16
HD 93206 is early-type massive stellar system, composed of components resolved by direct imaging (Ab, Ad, B, C, D) as well as a compact sub-system (Aa1, Aa2, Ac1, Ac2). Its geometr…
Towards a consistent model of the hot quadruple system HD 93206 = QZ Carinae - I. Observations and their initial analyses
P. Harmanec, P. Zasche, M. Brož +17
The hot nine-component system HD 93206, which contains a gravitationally bounded eclipsing Ac1+Ac2 binary (~d) and a spectroscopic Aa1+Aa2 (~d) binary can provi…
A new look into putative duplicity and pulsations of the Be star CMi
P. Harmanec, M. Svanda, D. Korcakova +6
Bright Be star beta CMi has been identified as a non-radial pulsator on the basis of space photometry with the MOST satellite and also as a single-line spectroscopic binary with a…
Physical properties of seven binary and higher-order multiple OB systems
Pavel Mayer, Petr Harmanec, Rolf Chini +7
Analyses of multi-epoch, high-resolution (~ 50000) optical spectra of seven early-type systems provided various important new insights with respect to their multiplicity. First det…
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…
The Multiplicity of High-Mass Stars
R. Chini, A. Barr, L. S. Buda +5
We report about an ongoing photometric and spectroscopic monitoring survey of about 250 O- and 540 B-type stars in the southern Milky Way with the aim to determine the fraction of…
A spectroscopic survey on the multiplicity of high-mass stars
R. Chini, V. H. Hoffmeister, A. Nasseri +2
The formation of stars above about twenty solar masses and their apparently high multiplicity remain heavily debated subjects in astrophysics. We have performed a vast high-resolut…
