Stellar modelling of Spica, a high-mass spectroscopic binary with a beta Cep variable primary component
A. Tkachenko, J. M. Matthews, C. Aerts +16
Binary stars provide a valuable test of stellar structure and evolution, because the masses of the individual stellar components can be derived with high accuracy and in a model-in…
Spectroscopically resolving the Algol triple system
V. Kolbas, K. Pavlovski, J. Southworth +7
Algol ( Persei) is the prototypical semi-detached eclipsing binary and a hierarchical triple system. From 2006 to 2010 we obtained 121 high-resolution and high-S/N échelle spect…
Tracing CNO exposed layers in the Algol-type binary system u Her
V. Kolbas, A. Dervisoglu, K. Pavlovski +1
The chemical composition of stellar photospheres in mass-transferring binary systems is a precious diagnostic of the nucleosynthesis processes that occur deep within stars, and pre…
HD 183648: a Kepler eclipsing binary with anomalous ellipsoidal variations and a pulsating component
T. Borkovits, A. Derekas, J. Fuller +16
KIC 8560861 (HD 183648) is a marginally eccentric (e=0.05) eclipsing binary with an orbital period of P_orb=31.973d, exhibiting mmag amplitude pulsations on time scales of a few da…
Modelling of Sigma Scorpii, a high-mass binary with a Beta Cep variable primary component
A. Tkachenko, C. Aerts, K. Pavlovski +6
High-mass binary stars are known to show an unexplained discrepancy between the dynamical masses of the individual components and those predicted by models. In this work, we study…
The eccentric massive binary V380 Cyg: revised orbital elements and interpretation of the intrinsic variability of the primary component
A. Tkachenko, P. Degroote, C. Aerts +8
We present a detailed analysis and interpretation of the high-mass binary V380 Cyg, based on high-precision space photometry gathered with the Kepler space mission as well as high-…
