... Discovery of enrichment of the envelopes of post-AGB stars with heavy metals . As a result of monitoring carried out at the BTA telescope, a new phenomenon was discovered in the optical spectra of post-AGB supergiants with an emission at 21 ?m and an overabundance of carbon and heavy metals in the atmospheres - the splitting of the strongest absorption lines. ... Thus, we discovered for the first time the enrichment of the stellar envelope with heavy metals synthesized by the s-process. ...

Abstract -- Abundances of heavy elements decreases with increasing galactocentric distance almost in all disk galaxies. ... To explain this gradient in young objects and in the interstellar gas one has to assume that a typical disk galaxy is an open system, i.e. it expels some synthesized heavy elements into the circumgalactic space and/or accretes intergalactic gas with zero metallicity, with rates of both processes depending on the galactocentric distance. ...

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. ...

mabs , the B-band absolute magnitude is computed from the corrected magnitude btc and the distance modulus modz (from the redshift) or mod0 (redshift-independent). For nearby galaxies ( v < 500 km/s, modz is not computed because it would be too imprecise (the peculiar motions dominate the Hubble flow), and the absolute magnitude is computed as: mabs = btc - mod0 For more distant galaxies, it is computed as: mabs = btc - modz .

[ holding up CD model ] The Milky Way is 100,000 light years across, so it takes light 100,000 years to go from one end of the galaxy to another. The Sun is about half way from the center of the galaxy to the edge, so that's about 25,000 light years. ...
