Chapter 18: The Bizarre Stellar Graveyard

Chapter 18: The Bizarre Stellar Graveyard. What is a white dwarf?. White Dwarfs. Sirius B is the closest white dwarf to us. White dwarfs are the remaining cores of dead stars. Electron degeneracy pressure supports them against the crush of gravity. Sirius A + B in X-rays. White Dwarfs.

Stellar Evolution

Stellar Evolution. The birth, Life and Death of stars Assigned Reading: up to Chapter 12. A main sequence star is the one which is supported by hydrogen fusion. The main sequence exists because stars balance their weight with energy outflows, produced by nuclear fusion in their core.

Today in Astronomy 102: electron degeneracy pressure and white dwarfs

Today in Astronomy 102: electron degeneracy pressure and white dwarfs. Detailed description of degeneracy pressure: confinement by quantum repulsion (Pauli exclusion principle) leads to additional resistance to compression (wave-particle duality; Heisenberg uncertainty principle).
