Welcome to the Starburst and Galaxy Evolution website.

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

This process is thought to occur in circumstellar disks of gas and dust around young stars on rather short timescales : infrared surveys show that the number of low mass stars with disks drops dramatically for stars older than 10 Myr, suggesting that in order to form large solids before the disk disperses, the growth process has to take place within a few million years. ...

Observations of the local Universe clearly demonstrate that very active star formation phases (starbursts) are often associated with interacting and merging galaxies and that in these systems much of the short wavelength emission is absorbed by dust and re-emitted in the IR. ...

... The distributions of orbits eccenttricities and of angular momenta for the halo stars and the old disk population are considered. The distributions have gaps separating the halo from the disk and dividing the halo population into three groups. ... Рассмотрены распределения звезд гало и старого населения диска по величине эксцентриситета орбит и угового момента. Распределения имеют провалы, отделяющие гало от диска и делящие населения гало на три группы. ...

... In this Section we examine evolution of the number of binary X-ray sources in an arbitrary galaxy. ... However, the problem with its X-ray radiation spectrum remains unsolved because no objects of this type have been observed so far. ... The total X-ray luminosity from different types of objects is traced separately at any instant. First, we calculated the evolution of the X-ray luminosity   assuming a delta-function (instantaneous) shape for the star formation rate. ...
