The X-ray binary GX 339-4/V821 Ara: the distance, inclination, evolutionary status and mass transfer
Andrzej A. Zdziarski, Janusz Ziółkowski, Joanna Mikołajewska
We consider constraints on the distance, inclination and component masses in the X-ray binary GX 339--4 resulting from published works, and then construct detailed evolutionary mod…
Non-conservative mass transfer in stellar evolution and the case of V404 Cyg/GS 2023+338
Janusz Ziółkowski, Andrzej A. Zdziarski
We consider donor evolution and mass transfer in the microquasar V404 Cyg/GS 2023+338. Based on X-ray observations of its two outbursts, its average mass accretion rate is substant…
The mass, luminosity and mass-loss rate of the donor of the V1487 Aql/GRS 1915+105 binary system
Janusz Ziółkowski, Andrzej A. Zdziarski
The donor in the microquasar GRS 1915+105 is a low-mass giant. Such a star consists of a degenerate helium core and a hydrogen-rich envelope. Both components are separated by a hyd…
Galactic Collapsed Objects
Janusz Ziólkowski
Our Galaxy contains some 10^8 to 10^9 collapsed objects (neutron stars and black holes). Our knowledge of them is based on less than 2000 objects identified as radio pulsars, membe…
News from Galactic Black Holes
Janusz Ziółkowski
Present status of the possible black hole microlensing events and the present understanding of high frequency quasi-periodic oscillations in systems containing black hole candidate…
Black Hole Candidates
Janusz Ziółkowski
The state of the searches for isolated black holes, non-accreting black holes in binary systems and, finally, the accreting black holes in the X-ray binaries is presented. The thir…
