| List the different mass range |
|
Definition
• If stars mass is less than 0.08 solar mass (failed star)
• 0.08 to 0.4 solar mass (extremely low mass star)
• 0.4 to 8 solar mass ( low mass star)
• 8 to 25 solar mass (intermediate mass star)
• > 25 solar mass (high mass star) |

Term
| Why and when do stars evolve off the main sequence? |
|
Definition
| When core hydrogen fusion slows down and the mass becomes greater than 4.0 it becomes a giant |
|

|
Definition
| 1.4 M also known as the Chandrasekhar limit |

Term
|
Definition
| time slows down at higher speeds. At the speed of the light mass is zero |
|

Term
|
Definition
| mass increases with speed. at the speed of light mass becomes infinite |

Term
| Difference b/w nova and supernova |
|
Definition
| Supernova actually blow apart completely from its white dwarf even though both are in a binary system. Supernova is million times brighter & a star can only turn into a supernova once, but into a nova many times |

|
Definition
| Type I supernova happens when a white dwarf in a binary system explodes by accumulating mass more than Chandrasekhar limit. Type II supernova happens when a single star (mass more than 8 solar mass) explodes. Remember that another name for Type I supernova is carbon-detonation supernova and for Type II is core-collapse supernova. ) |
