Evolutionary Processes in Close Binary Systems
- B. Paczyński

- 1971
The structure and evolution of the stars constitute one of the main prob lems of modern astrophysics. Binary stars are so common that it is not pos sible to develop a comprehensive theory of…
Gravitational microlensing by the galactic halo
- B. Paczyński
- Physics, Geology
- 1 May 1986
A simple model of microlensing by massive objects that might be present in the halo of the Galaxy is presented. It is shown that in any nearby galaxy one star out of a million is strongly microlensed…
A model of accretion disks in close binaries.
- B. Paczyński
- Physics, Geology
- 15 September 1977
The simple periodic orbits of a test particle in the restricted three-body problem are a very good approximation to the streamlines in the accretion disk with a very small pressure and viscosity. The…
Gamma-ray bursters at cosmological distances
- B. Paczyński
- Physics
- 15 September 1986
It is proposed that some, perhaps most, gamma-ray bursters are at cosmological distances, like quasars, with a redshift of about 1 or 2. This proposition requires a release of supernova-like energy…

A test of the galactic origin of gamma-ray bursts
- B. Paczyński
- Physics, Geology
- 1990
Models in which gamma-ray bursters are young neutron stars may be difficult to reconcile with the apparently isotropic distribution of observed bursts. To justify this statement, the distribution of…
The Optical Gravitational Lensing Experiment. The Optical Depth to Gravitational Microlensing in the Direction of the Galactic Bulge
- A. Udalski, M. Szymański, R. Venkat
- Physics, Geology
- 1 April 1994
We present the analysis of the first two years of the OGLE search for gravitational lenses towards the Galactic bulge. We detected 9 microlensing events in an algorithmic search of $ \sim 10^8 $…
An evolution free test for non-zero cosmological constant
- C. Alcock, B. Paczyński
- PhysicsNature
- 4 October 1979
The cosmological constant has recently been questioned because of difficulties in fitting the standard Λ=0 cosmological models to observational data1,2. We propose here a cosmological test that is a…
Models of X-ray bursters with radius expansion
- B. Paczyński
- Physics
- 1 April 1983
A series of models of helium shell flashes ;on a neutron star is presented. To make models simple, no hydrogen was present and a small nuclear reaction network was used. General relativity was fully…
