... An alternate model dominated by smaller grains, near the blowout size a~0.5 ЮМm, located at 30-40 AU is also possible but requires the dust to have been produced recently, since such small grains will be expelled from the system by radiation pressure in approximately a few times 102 yr. ...

... Initially SAI Supernova Catalogue was presented in the form of filebased system. ... The current version of SAI Supernova Catalogue presents data on supernovae together with data on their parent galaxies. ... The main source of data for the galaxies was LEDA database. ... In some cases our data were compared with the ones from the Asiago Supernova Catalogue and from List of Supernovae at Harvard-Smithsonian Center for Astrophysics, but the compilation of our Catalogue is carried out independently. ...

... 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. ...

Observations of the local Universe clearly demonstrate that very active star formation phases (starbursts) are often associated with interacting and merging galaxies and that in these systems much of the short wavelength emission is absorbed by dust and re-emitted in the IR. ...
