... 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. ...

Next: The Supernovae Rates Up: No Title Previous: Gravitational wave background from . In this Section we present the results of the Scenario Machine simulation of supernova explosion (SN) rates in the Galaxy for various types of supernovae and apply them for estimating the - dependence for the SN in the Universe (see JЖrgensen et al. 1995[ 80 ]). The Supernovae Rates . Dependence for the Supernova Explosions . for Supernova Explosions . Results and Discussion . ...

... 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. ...

We study the magnetic field structure and evolution for 26 X-ray brightening events in coronal holes and quiet Sun regions, including bright points and jets. We found that all brightening events are associated with bipolar regions and caused by magnetic flux emergence followed by cancellation. ... Comparing coronal holes and the quiet Sun, we do not find differences in their corresponding magnetic field behavior. ...

EVOLUTION OF GALACTIC DISCS: TWO MODES OF STAR FORMATION ABSTRACT We develop the model of the evolution of surface gas density, stellar density, star formation rates and chemical composition of galactic disc taking into account the gravitational instability of rotating gaseous layer in the scales of several kpc. ... In the model we took into account the gas return from evolved stars, a radial movement of the gas in a spiral arms and accretion of the gas into the galactic disc. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...
