13. 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. ...

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. ...
