Refined reduction and standardisation of 53 years of UBV photometry at Hvar
Hrvoje Božić, Petr Harmanec, Miroslav Brož +17
Emission-line stars classified as Be exhibit light and colour variability on various timescales, ranging from days to decades. Their evolution must be constrained by long-term obse…
Spectroscopic orbit and variability of the Be star V1624 Cyg = 28 Cyg
P. Harmanec, S. Yang, P. Koubský +8
In recent years the idea, first formulated many decades ago, that the Be phenomenon could be causally related to the duplicity of Be stars, has been repeatedly reconsidered from va…
Spectrum of the secondary component and new orbital elements of the massive triple star Delta Ori A
A. Oplištilová, P. Mayer, P. Harmanec +13
Orionis is the closest massive multiple stellar system and one of the brightest members of the Orion OB association. The primary (Aa1) is a unique evolved O star. In this work,…
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…
V1294 Aql = HD 184279: A bad boy among Be stars or an important clue to the Be phenomenon?
P. Harmanec, H. Božić, P. Koubský +21
A reliable determination of the basic physical properties and variability patterns of hot emission-line stars is important for understanding the Be phenomenon and ultimately, the e…
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…
