The above process keeps the # of protons and the # of neutrons in the early Universe constant. ...

Prague, August 16, 2006 . To start a new GCVS edition (presumably an electronic one), combining the stars of the GCVS IV and Name Lists (and maybe eventually merged with automatic-survey variables), we need to revise the GCVS classification system. ... Our approach: the classification scheme must be simplified, more detailed classification should be given in specialized catalogs for particular types, but the GCVS classification should take into account new astrophysics. ...
