White Dwarf and Pre-White Dwarf Oscillations [PDF]
International Astronomical Union Colloquium, 1993 AbstractCompact stars that result from extreme mass loss on the asymptotic giant branch and planetary nebula formation are observed to pulsate in a very large surface effective temperature range as they cool to become the classical white dwarfs. The hottest and most luminous of these display periods in excess of 1000 seconds because they are large, but

Luminosity and cooling suppression in magnetized white dwarfs [PDF]
, 2018 The 21st European Workshop on White Dwarfs was held in Austin, TX from July 23rd to 27th of 2018We investigate the luminosity and cooling of highly magnetized white dwarfs where cooling occurs by the diffusion of photons.

White Dwarfs In Ngc6397 And M4: Constraints On The Physics Of Crystallization [PDF]
, 2010 We explore the physics of crystallization in the dense Coulomb plasma of the deep interiors of white dwarf stars using the color-magnitude diagram and luminosity function constructed from Hubble Space Telescope photometry of the globular cluster M 4 and ...
