Sol, aka the Sun, is a great example of this. Solar equilibrium means that the star is stable and fusing hydrogen into helium. Main sequence stars vary by mass, which in turn changes two other properties: color and temperature. The hotter a main sequence star is, the larger it is at well. This means that hydrogen fusion is occurring at a much faster rate. This change in fusion rate also determines the evolution the star will undergo, meaning it will become one of three things: a white dwarf star, a neutron star, or a black hole.]]> 2018-10-09 12:59:27 UTC https://padlet.com/cblatt88/mth6hwluplmz/wish/290702805 cblatt88 https://padlet.com/cblatt88/mth6hwluplmz/wish/290706844 Sol, our Sun, is a low mass star. It is however, on the heavier end of the low mass spectrum. Stars that are even lower in mass are either orange or red, versus Sol's bright yellow glow. Because they are so stable and small, they burn for 10 billion years on average. A low mass star ends its life-cycle as a white dwarf after it first becomes a red giant and explodes into a planetary nebula.]]> 2018-10-09 13:05:48 UTC https://padlet.com/cblatt88/mth6hwluplmz/wish/290706844 cblatt88 https://padlet.com/cblatt88/mth6hwluplmz/wish/290707689 Some high mass stars can be yellow as well, but most of them are blue. They are "shine" much, much brighter than low mass stars. They fuse hydrogen at such a fast rate they only live for a few million years, compared to a low mass star's 10 billion year lifetime. Once hydrogen fusion ends, a high mass star will grow to become a red super giant and eventually explode as a supernova. Depending on the original mass of the star, after the supernova it will become a neutron star of a black hole.]]> 2018-10-09 13:07:04 UTC https://padlet.com/cblatt88/mth6hwluplmz/wish/290707689 cblatt88 https://padlet.com/cblatt88/mth6hwluplmz/wish/290977642 A comparison of stars by temperature, mass, and their habitable zones.]]> 2018-10-09 19:38:55 UTC https://padlet.com/cblatt88/mth6hwluplmz/wish/290977642 cblatt88 https://padlet.com/cblatt88/mth6hwluplmz/wish/290988666 2018-10-09 20:07:42 UTC https://padlet.com/cblatt88/mth6hwluplmz/wish/290988666 cblatt88 https://padlet.com/cblatt88/mth6hwluplmz/wish/290988875 2018-10-09 20:08:27 UTC https://padlet.com/cblatt88/mth6hwluplmz/wish/290988875
