On Earth high mass protostars would be considered a vacuum. They are hard to see because their light is blocked by dust surrounding it.]]> 2022-10-19 18:59:29 UTC https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347660236 coffeye11 https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347663879 A blue main sequence star is a main sequence star of spectral type B and luminosity class V. These stars have from 2 to 16 times the mass of the Sun and surface temperatures between 10,000 and 30,000 K. ]]> 2022-10-19 19:01:38 UTC https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347663879 coffeye11 https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347666236 The stars outer layers expand while the core is shrinking, increasing the luminosity. This expansion takes a billion years and the radius increases 100 times. Eventually the core becomes hotter and denser and reaches a temperature of 100million K and the helium nuclei begin to fuse into carbon.]]> 2022-10-19 19:03:03 UTC https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347666236 coffeye11 https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347729730 As the helium in the core is exhausted, the star begins helium burning in a shell around an inert carbon core while moving again up the H-R diagram to become a Red Supergiant.]]> 2022-10-19 19:42:49 UTC https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347729730 coffeye11 https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347733038 High mass stars will develop into a heavy element fusing core, and multiple shell burning outer envelop, releasing large amount of energy.]]> 2022-10-19 19:45:10 UTC https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347733038 coffeye11 https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347738093 Gradually, heavier elements build up to the center which at one point surpasses the mass it can handle.

It is what is left over after a supernova explosion. When a high mass star comes to the end of its lifetime, its outer layers collapse onto the core. This squashes the star's core to the point where the atoms are smashed apart, leaving only neutrons.]]> 2022-10-19 19:51:30 UTC https://padlet.com/coffeye11/pcthmihj21lobqrb/wish/2347741077
