  • Help! Ashley I need help understanding Yellow stars!
  • Ashley: Hmm, well first the star would start off as a Stellar Nebula. Then it will be a protostar. This is when the protostar would convert its hydrogen into helium, the gravity would pressure the star to make a nuclear reaction. It would later become really hot and turn into a red giant. The outer layers and the core will spilt up and become a planetary nebula. Later it becomes a white dwarf, which will last for millions of years and finally turn into a black dwarf where it would lose its luminosity and then it will sadly die.
  • Ashley: What do you need to know?
  • Rose: Well, what's a yellow star's life cycle?
  • Rose: wow, thats cool!
  • Rose: What are blackbody radiators?
  • Rose: Okay, so are life cycles different for other types of star? Or are they the same? 
  • Ashley: Yes, life cycles are different for other kinds of stars, if the star is bigger than a basic yellow star then it would go through a stellar nubula, massive star , red super giant, supernova, then it can either become a neuton star or a black hole.
  • Ashley: Blackbody radiators are radiator based on light, which depend on temperature in which the object would absorb all the colors and become black.
  •  Rose: Well um, I know that there are stars that are different color and masses, but how would know which are which kinds?
  •  Ashley: Well, if the star is blue, then he star is extremely hot. And if the star is red, then it is cold. This is because of electromagnetic radiation.  The radiator reflects a color for our eyes to see and absorbs the other colors. 
  •  Ashley: Well, there are different ways to classify the stars. By mass, color, luminosity, and temperature.
  • Rose: Wow, thats cool! Alright, so what about temperature? How would scientists find that out? 
  • Ashley: So scientists find out a star's temperature by measuring the luminosity of a star by how red or blue the star is. They would compare the colors and find out the relative temperature. Or if they have it in an HR-Diagram, then they can just see where they have the star on the temperature scale.
  • Rose: Wow! Thanks Ashley!
  • Ashley: No problem?
