Lecture #6

White dwarf

Pressure = (# particle)(velocity)(mass)

Quantum pressure

Reached at very high pressures

Special relativity

Assumptions

Speed of light is constant

All inertial observers are equal

Results

Time dilation

Length contraction

Simultaneity not preserved

Lecture #7

Special Relativity

Neutron Star & Black Hole formation

Electron pressure increase beyond limit

Generate neutron rich atoms

Neutron bleed out = quantum pressure

High Mass Stars

Core collapse due to Fe disintegration

"bounce" causes type II supernovae

Black Hole

Event horizon

Lecture #8

Binary Star Systems

Two stars gravitationally bound

Primary,

Secondary,

Orbital period/separation

Roche Lobes

Mass exchange between stars

X-ray binaries
