A global view on the colliding-wind binary WR 147
Svetozar A. Zhekov, Blagovest V. Petrov, Toma V. Tomov +1
We present results from a global view on the colliding-wind binary WR 147. We analysed new optical spectra of WR 147 obtained with Gran Telescopio CANARIAS and archive spectra from…
International observational campaign of the 2014 eclipse of EE Cep
D. Pieńkowski, C. Gałan, T. Tomov +64
Context. EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to ε Aur. The system is characterized by grey and asymmetric eclip…
XMM-Newton observations of the symbiotic recurrent nova T CrB: evolution of X-ray emission during the active phase
Svetozar A. Zhekov, Toma V. Tomov
We present an analysis of the XMM-Newton observations of the symbiotic recurrent nova T CrB, obtained during its active phase that started in 2015. The XMM-Newton spectra of T CrB…
High-resolution optical spectroscopy of Nova V392 Per
K. A. Stoyanov, T. Tomov, I. Stateva +1
Here we analyze high-resolution spectra of the Nova V392 Per obtained during the 2018 outburst. The H and H emission lines show a triple-peak structure with radial velocities…
An XMM-Newton observation of the symbiotic star AG Peg: the X-ray emission after the end of its 2015 outburst
Svetozar A. Zhekov, Toma V. Tomov
We present an analysis of the XMM-Newton observation of the symbiotic star AG Peg, obtained after the end of its 2015 outburst. The X-ray emission of AG Peg is soft and of thermal…
Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters
Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5
Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…
