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…
EPIC 216747137: a new HW Vir eclipsing binary with a massive sdOB primary and a low-mass M-dwarf companion
R. Silvotti, V. Schaffenroth, U. Heber +8
EPIC 216747137 is a new HW~Virginis system discovered by the Kepler spacecraft during its K2 "second life". Like the other HW Vir systems, EPIC 216747137 is a post-common-envelope…
The EREBOS project -- Investigating the effect of substellar and low-mass stellar companions on late stellar evolution
V. Schaffenroth, B. N. Barlow, S. Geier +14
Eclipsing post-common envelope binaries are highly important for resolving the poorly understood, very short-lived common envelope phase. Most hot subdwarfs (sdO/Bs) are the bare H…
The ESO supernovae type Ia progenitor survey (SPY)
R. Napiwotzki, C. A. Karl, T. Lisker +13
Close double degenerate binaries are one of the favoured progenitor channels for type Ia supernovae, but it is unclear how many suitable systems there are in the Galaxy. We report…
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…
