SUMMARY:Quasi-stars\, giants and the Schönberg-Chandrasekhar limit - Warr

DESCRIPTION:The Schönberg-Chandrasekhar (SC) limit is a well-established 
 result in stellar evolution. I explain the SC limit in terms of contours o
 f constant fractional mass for polytropic envelopes in the plane of homolo
 gy invariant variables U and V. In the same way\, I explain the inner mass
  limit we previously found for quasi-stars: black holes embedded in and ac
 creting from hydrostatic\, giant-like envelopes. It also demonstrates that
  SC-like limits exist under a wide range of circumstances. One can test wh
 en a star is at a broader SC-like limit and I discuss possible consequence
 s for post-main-sequence stellar evolution.\n
