The Donor of the Black-Hole X-Ray Binary MAXI J1820+070
Joanna Mikolajewska, Andrzej A. Zdziarski, Janusz Ziolkowski +2
We estimate the parameters of the donor of the accreting black-hole binary MAXI J1820+070. The measured values of the binary period, rotational and radial velocities and constraint…
A comment on the properties of the matter flow through the first Langrangian point
Janusz Ziolkowski, Andrzej A. Zdziarski
We analyse properties of the mass outflow from the Roche-lobe filling component of a semi-detached binary system. We follow the approaches published by Paczyński \& Sienkiewicz and…
Cygnus X-1 contains a 21-solar mass black hole -- implications for massive star winds
James C. A. Miller-Jones, Arash Bahramian, Jerome A. Orosz +23
The evolution of massive stars is influenced by the mass lost to stellar winds over their lifetimes. These winds limit the masses of the stellar remnants (such as black holes) that…
The nature of the Schoenberg-Chandrasekhar limit
Janusz Ziolkowski, Andrzej A. Zdziarski
We present a comprehensive description of the Schönberg--Chandrasekhar (S--C) transition, which is an acceleration of the stellar evolution from the nuclear to the thermal time sca…
IGR J17451--3022: constraints on the nature of the donor star
Andrzej A. Zdziarski, Janusz Ziolkowski, Enrico Bozzo +1
We constrain the binary parameters of the eclipsing accreting X-ray binary IGR J17451--3022 and the nature of its donor star. The donor mass, its radius, and the system inclination…
On the masses of the components of the V1387 Aql/GRS1915+105 binary system
Janusz Ziolkowski
V1387 Aql (the optical companion to the microquasar GRS1915+105) is a low mass giant. Such star consists of a degenerate, nearly isothermal helium core and a hydrogen rich envelope…
