Paper 3 Review

The outcome of a star depends on the star's initial mass (in terms of solar masses).

• <0.25
• 0.25 - 4 White dwarf with carbon/oxygen core
• 4 - 8 White dwarf with oxygen/neon/magnesium core
• 8 - 40 Neutron star
• >40 Black hole

Fg = GMm/r^2

b = L/4πd^2 units: W/m^2

The Schwarzschild radius is the distance from the center of a black hole within which no light is able to escape.
