Figure 55 shows the ``Green functions'' for the double compact binary merging rate evolution assuming no collapse anisotropy. ... Another way that diverse peculiarities in the - distribution induced by the sources evolution could arise is connected with a possible non-monotonic character of the star formation rate in galaxies. ... 22 ] Figure 56 shows two-dimensional cuts through the parameter space. ...

... My main research interests involves: the role of evolution in galaxy properties; the environmental effects in galaxy evolution/formation; the properties of star-forming galaxies at low and high redshifts. I am using IUE data to build a library of B stars and extend a stellar synthesis code (Leitherer & Heckman 1995) in order to reproduce the observed galaxies properties. I am using CO data of galaxies at different environments in order to study the influence of interaction in the gas. ...

9. Informational system "Evolution of RG"
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. ...

... More recently, I have been concerned with observing masers located in the circumstellar shells generated by red giant stars in their mass-loss phase, and in what we can therefore learn about the late stages of stellar evolution. 100 mJy are now undetectable after ~12 years, aka the DEATH of an OH/IR star or its cyclical evolution back to a Mira variable. ... I find that this momentum flux is sufficient to support the largest observed rates of AGB mass-loss. last updated: 14 January 2015 . ...

13. Conclusions
Next: About this document Up: Contents Previous: Rapidly Rotating Stars . ... By studying the rotation of PMS stars in Orion OB1a and OB1b, I hoped to gather some insights to the evolution of rotation in young stars. ... The small size of the data set which could be processed this way and the large variations within the dereddened group made age determination difficult, but showed that the Orion OB1b stars are about 0.5 dex older than the Orion OB1a stars. ... Such stars are unable to spin--up. ...

18. ASP: An Ancient Universe - Changes in Stars
An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE CHANGING UNIVERSE: EVOLUTION HAPPENS! . b) Changes in Stars . One of the great discoveries of modern science is that stars (like people) live only a measurable life-time and then die. Although the lives of the stars are enormously longer than the span of a human life, we can learn about the life story of the stars by studying them at many different stages in their life cycle, from birth to death. ...
