To investigate the late stages of stellar evolution and in particular the role of stellar mass-loss in the evolution of asymptotic giant branch stars, proto-planetary nebulae and extremely massive stars. ...

Since 1994, the Astronomical Society of the Pacific's (ASP) highly successful national Project ASTRO? program has been providing opportunities for professional and amateur astronomers to contribute to science education in their local communities. ... The original "classic" Project ASTRO educator-astronomer partners found tremendous interest in what they were doing among the families of their students, and thus Family ASTRO was born to continue at home what was begun in the classroom. ...

We are looking for an enthusiastic PhD student who is interested in working with us in using ALMACAL to address exciting and topical science questions related to the evolution of molecular gas in galaxies. ...

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. ...

Next: The equilibrium period Up: Evolution of Magnetic Rotators Previous: Evolution of Magnetic Rotators . Analysis of the nature of interaction of a magnetized star with the surrounding plasma allows us to write an approximate evolution equation for the angular momentum of a magnetic rotator in the general form (Lipunov, 1982a[ 98 ]) . where is a specific angular momentum applied by the accretion matter to the rotator. ... The evolution equation ( 4.10.2 ) is approximate. ...

... PREBIOLOGICAL PANSPERMIA AND THE HYPOTHESIS OF THE SELF-CONSISTENT GALAXY ORIGIN OF LIFE . ... The evolution of the civilization is even faster. ... Thus the scale of the duration of the 'natural' planetary prebiological chemical evolution may be ~10 billion years (and there is no time for such long prebiological evolution on the Earth of course). ... In this situation the prebiological chemical evolution may not be isolated on any single planet from the all-Galaxy prebiological infection. ...

... 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. ...
