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. ...

Stars form from interstellar clouds rich in hydrogen....they shine for billions of years, gradually converting hydrogen into helium....when hydrogen is exhausted, they need to find other energy sources....they expand to become giants and supergiants....low-mass stars expel planetary nebulae and become white dwarfs....high-mass stars explode as supernovae, leaving a neutron star or black hole behind. ... What can they tell us about normal stellar evolution ? ... WWW contact: webmaster@star.arm.ac.uk . ...

... Galaxy Evolution home . Cavendish Astrophysics . ... Cosmological evolution of star-forming galaxies . The origin and evolution of radio sources . ... Radio sources are among the most powerful of the family of Active Galactic Nuclei (AGN). ... The overall properties of radio sources are well predicted by analytical models of self-modifying evolution of the radio source which we have developed, and many of the more unusual structures observed can be reproduced using computational models. ...

... 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. ...

Amanda Karakas One of the most important research fields in astrophysics is the study of the origin of the elements. ... Asymptotic Giant Blanch (AGB) Stars: For low and intermediate-mass stars (with initial masses between about 0.8 to 8 solar masses) the most important nucleosynthesis occurs when stars evolve off the main sequence to the giant branches. ... This indicates that these stars obtained their unusual abundances via mass transfer from a previous red giant star, that has long evolved away. ...
