We present the first realistic set of arbitrarily degenerate stellar models appropriate for donors in ultracompact binaries. The mass-radius M-R relations for these objects are parameterized by the donor's entropy and composition. We highlight how this fact can affect our understanding on the current configuration of ultracompact binaries today and their potential evolutionary tracks.

Resumen

Resumen

Presentamos el primer conjunto realista de modelos estelares arbitrariamente degenerados, apropiados para donadores en binarias ultracompactas. Las relaciones masa - radio, M-R, de estos objetos son parametrizadas por la entropía y la composición del donador. Enfatizamos que nuestra comprensión de la configuración actual de binarias ultracompactas y sus potenciales trazas evolutivas pueden estar afectadas por este hecho.
