Eugen Piwowarskyevaluation first shows that the settling time scale varies by 4 or 5 orders of magnitude over the effective temperature range from 4000 to 10,000K. The mixing length was determined using the Sun and the evolutionary calculations then calculated without adjustable parameters. In stars of around 1.4 s

Eugen Piwowarsky, degeneracy is lifted in the core and the star moves to the Horizontal Branch (HB in what follows). HB stars are thought to burn He in their center and to have a H envelope. The central region of HB stars is like a He star. The surface .. depends on the thickness of the remaining H envelope above t
