WebJun 30, 2015 · Simulations of Population III stars and the transition to metal-enriched star formation suggest that the smallest halos to form stars have masses of around 10 6 –10 7 (O'Shea & Norman 2007; Johnson et al. 2008; Smith et al. 2009; Wise et al. 2012b; Crosby et al. 2013), with correspondingly few stars and low luminosities. These simulations ... WebAccording to stellar evolution theory, no star of such low mass can have evolved to that stage within the age of the Universe. In stars above about 0.4 M☉ the core temperature eventually reaches 10 8 K and helium will begin to fuse to carbon and oxygen in the core by the triple-alpha process. [5] ,§ 5.9, chapter 6.
