X-ray emission from helium star+black hole binaries as probes of tidally induced spin-up of second-born black holes
Koushik Sen, Aleksandra Olejak, Sambaran Banerjee
Tidally induced spin-up of stripped helium stars in short-period (<\,1\,d) binaries with black holes has been presented as one of the possible mechanisms to reproduce the high-spin…

SV Cen reveals its mystery
Michal Siwak, Stanislaw Zola, Slavek Rucinski
Our very-first high resolution spectra of SV Cen close binary system obtained in the H alpha line reveal its absorption and emmision components, changing with orbital phase. An acc…

Numerical Simulations of Rotating Accretion Flows near a Black Hole
Dongsu Ryu, Sandip K. Chakrabarti
We present time-dependent solutions of thin, supersonic accretion flows near a black hole and compare them with analytical solutions. Such flows of inviscid, adiabatic gas are char…
