Boundary layer on the surface of a neutron star
N. Babkovskaia, A. Brandenburg, J. Poutanen
In an attempt to model the accretion onto a neutron star in low-mass X-ray binaries, we present two-dimensional hydrodynamical models of the gas flow in close vicinity of the stell…
A warped m=2 water maser disc in V778 Cyg?
Natalia Babkovskaia, Juri Poutanen, Anita M. S. Richards +1
The silicate carbon star V778 Cyg is a source of 22 GHz water maser emission which was recently resolved by MERLIN. Observations revealed an elongated S-like structure along which…
A self-consistent model of a 22 GHz water maser in a dusty environment near late-type stars
Natalia Babkovskaia, Juri Poutanen
We study the conditions for operation of the 22 GHz ortho-water maser in a dusty medium near late-type stars. The main physical processes, such as exchange of energy between dust a…
Oxygen-rich disk in the V778 Cyg system resolved
R. Szczerba, M. Szymczak, N. Babkovskaia +3
Various scenarios have been proposed to explain the presence of silicate features associated with carbon stars, such as V778 Cyg. We have attempted to constrain these theories by m…
Water masers in dusty environments
Natalia Babkovskaia, Juri Poutanen
We study in details a pumping mechanism for the lambda=1.35 cm maser transition 6_16 -> 5_23 in ortho-water based on the difference between gas and dust temperatures. The upper mas…
