  • Dear chase, how does the initial mass of a low mass star affect it evolution?  thanks jason
  • well jason If the star has smaller mass than the sun, it can fuse hydrogen into helium for  trillions of years  
  • scientists can  find out a star's temperature is by the stars color, which is used in a H-R diagram
  • thanks but i'm having trouble with this question to, how can scientists find out out the  temperature of a star? 
  • well jason hot stars appear blue because most energy is emitted in the bluer parts of the Em spectrum, There is little emission in the parts of the EM spectrum for cool stars (they appear red). It  also has to do with the wavelengths the longer wavelengths are red and the shorter ones are blue.
  • thanks but i'm also having trouble with this question, Why do hot stars appear to be blue? Why do cool stars appear to be red?
  • The life cycle of a low mass star (from the begin to the end)
  •     1. Is the stellar Nebula this is the prostar composed of dust  clouds. In this stage the star is trying to achieve equilibrium between gravity.                                                         
  • 
  • 2. average star after achieving equilibrium, the star begins burning up its supply of hydrogen and helium through nuclear fusion.
