- The Life Cycle of Larger Stars
- Diagram/Chart
- Protostar
- Nebula (Starting Point)
- Main Sequence
- SuperNova
- NeutronStar
- Blackhole
- If core is >3M
- Blackhole
- >10M
- Main Sequence
- SuperNova
- NeutronStar
- If core is >3M
- >10M
- 0.1M to 10M
- White Dwarf
- White Dwarf
- SuperNova
- Main Sequence
- 0.1M to 10M
- White Dwarf
- White Dwarf
- SuperNova
- < 1M
- Brown Dwarf
- Protostar
- Nebula (Starting Point)
- < 1M
- Brown Dwarf
- Brown Dwarf
- Protostar
- Brown Dwarf
- Protostar
- What Hapens next
- Depeneds on the mass of the core
- Below the Chandrasekhar Limit
- Electrons cant be sqeezed together
- Biggest mass white dwarf can have
- Electrons cant be sqeezed together
- From 1.44 - 3M
- Electrons and protron squeeze into neutrons
- Neutron degeneracy pressure prevents furhter collapse
- Electrons and protron squeeze into neutrons
- Greater than 3M
- Matter collapeses completely
- A Point of Infinetie density occurs which is called a black hole
- Matter collapeses completely
- Neutron Stars
- Very Dense - the mass of our sun into 10km
- Pulsars
- Roatating neutron star
- On an axis
- Emits beams of radiation (radio waves)
- This may appear to us as pulses
- Roatating neutron star
- Blackholes
- Mass is so great, nothing can stop gravity from collapsing the star
- Matter collapsed to a point of infinete density
- Escape velocity greater than speed of light
- Anything that gets within a certain distance (the event horizon)will never escape
- There could be more than a million black holes in jsut the milky way
- At the center of every galaxy is a super massive black hole
- The one at the center of ours hass the mass of 4 million suns
- Evidence for black holes
- Gravitation effects on other objects
- gravitational effects on light and other EM waves
- Material in the accretion disc (spins super fast) around a black hole
- gets very hot and emits X rays
