... We propose that the bimodal nature of the kick velocity distribu­ tion of radio pulsars is connected to the dichotomy between hadronic stars (i.e. neutron stars with no quark matter content) and quark stars. ... Here we propose a scenario in which the low­velocity part of the distribution is connected with normal (hadronic) compact stars, and high­velocity part is formed by objects with some amount of quark matter inside (hybrid or strange stars). ...

One of the Hubble Space TelescopeтАЩs goals was to accurately observe Cepheids in the most distant galaxies known (we knew they were far away, the problem was saying just how far). ... This work is becoming ever more refined; in January this year astronomers revealed that they had identified the farthest galaxy yet seen in a Hubble image. ... Thanks to the Hubble Space TelescopeтАЩs superb observations we can say that the universe is 13.75 billion years old. ...

Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...

... It was found that the Sun lies 9?2 pc above the plane of hte Galactic disk in the direction of North Galactic pole and that F0-F9 stars contribute 0.0035 M /pc 3 to the density of the Galactic disk. ... We used this method to determine the scale height of the subsystem of F stars of the Galactic disk, Z 0 =160?10 pc. ... It is suggested that scale height of the metal-poor stars subsystem is due to the infall of the metall-poor intergalactic gas onto the disk. ...

One of the prominent scientists of the 20th century Gamow was born in Odessa on March 4, 1904 in the family of a secondary school teacher. ... In 1994, in the year of his 90-th anniversary, an International Conference "Astrophysics and cosmology after Gamow" was held in Odessa and St.Petersburg. The idea of this conference is supported by the UNESCO representation in Russia and by the International Renaissance Foundation (Odessa branch) (affiliation of the Soros Foundation). ...
