Stars generally form when a nebula gets nudged into gravitational collapse. The densest regions collapse the fastest, giving birth to the biggest stars. Then less dense regions collapse, forming smaller stars. This leads to a sort of hierarchical process that ends up with a small number of large stars and a large number of small stars.<br /><br />It's also true that the big stars don't last as long, and this biases our observations of stellar populations. But when we look at active star-forming regions, we see more red ones than blue ones. (As long as we're not looking too far away. If we can't resolve individual stars, we see more blue than red, because blue stars are brighter than red stars, even if they're outnumbered.)Ori Vandewallehttps://www.blogger.com/profile/17804391682393947159noreply@blogger.comtag:blogger.com,1999:blog-8331666102432713341.post-17945867855597817472016-03-03T17:36:21.236-05:002016-03-03T17:36:21.236-05:00Just to be a total pedant on you: you got cause an...Just to be a total pedant on you: you got cause and effect garbled in saying "There are many more small stars than big stars in the universe, with the consequence being that most stars are red dwarfs" didn't you? Small stars burn lower and last multiple orders of magnitude longer than big ones is why most stars are red dwarfs, isn't it?BUhttp://alphacentauri2.info/index.php?action=communitynoreply@blogger.com
