Chandrasekhar-Schonberg limit
subjectfact 
Chandrasekhar-Schonberg limithas definition Mass above which the helium core of a star begins to contract (eventually to collapse altogether). The limit is now reckoned as 10 to 15 per cent of the star's total mass.has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:33:14.0
has definition The mass limit for an isothermal core. In order to maintain its luminosity by hydrogen burning just outside the isothermal core, the star must keep a high temperature and a high pressure at the surface of the core. When the helium core exceeds about 12% of the star's total mass, the star can no longer adjust by small changes, but must drastically increase in radius and move rapidly from the main sequence.has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:33:14.0
