CoBiToM project. III. Physical characterisation of the potential merger candidates AL Lep, ASAS J082243+1927.0, and ZZ PsA
Sofia Palafouta, Kosmas D. Gazeas, Pasi Hakala +3
Contact binaries (CBs) are key systems for investigating the late evolutionary stages that may lead to stellar coalescence. Systems with an extremely low mass ratio and high fill-o…
Eccentric orbits and apsidal motion in the eclipsing binaries EK Cep and HS Her
Olivera Latković, Kosmas Gazeas, Haralambi Markov +2
We present the first modern analysis of two young, eclipsing binaries, EK Cep and HS Her, based on new, ground-based, CCD multicolour light curves as well as the TESS observations,…
CoBiToM Project -- II: Evolution of contact binary systems close to the orbital period cut-off
G. A. Loukaidou, K. D. Gazeas, S. Palafouta +7
Ultra-short orbital period contact binaries (Porb < 0.26 d) host some of the smallest and least massive stars. These systems are faint and rare, and it is believed that they have r…
CoBiToM Project -- I. Contact Binaries Towards Merging
K. D. Gazeas, G. A. Loukaidou, P. G. Niarchos +6
Binary and multiple stellar systems are numerous in our solar neighborhood with 80 per cent of the solar-type stars being members of systems with high order multiplicity. The Conta…
CzeV1731: The unique doubly eclipsing quadruple system
P. Zasche, Z. Henzl, H. Lehmann +14
We report the discovery of the relatively bright (V = 10.5 mag), doubly eclipsing 2+2 quadruple system CzeV1731. This is the third known system of its kind, in which the masses are…
