Theoretical upper size limit for a star

WebbThere is a hypothesized upper size limit. http://www.space.com/858-study-stars-size-limit.htmlBut it concerns only the birth of new stars. But at least one star larger than that upper size limit has been observed, though it is speculated that this could have been formed from the merging of smaller stars. 1 Share ReportSave level 2 · 8 yr. ago WebbThe theorectical limit was calculated to be around 33%. That means on a sunny day a silicon solar cell with one p-n junction could collect up to 33% of the sun's rays. Of course the technology was not there to come close to 33%, it was more like 10% for many reasons.
