Does anyone know if there is an index of all the old White Dwarfs, or even better a pdf old archive? I'm trying to find some old articles and any... White dwarfs are the final remnants of low- and intermediate-mass stars. Their evolution is essentially a cooling process that lasts for $sim 10$ Gyr. Their observed properties provide information about the history of the Galaxy, its dark matter content and a host of other interesting astrophysical problems. Examples of these. A basic understanding has already emerged, but many problems remain to be solved. (Koester 1987a). Progress in this and other fields of white dwarf research is of course intimately con- nected to progress in observational methods and instrumentation. The last decade has seen tremendous technical advances due to the. of 83 white dwarfs.

The desorption of molecular species from ice mantles back into the gas phase in molecular clouds results from a variety of very poorly understood. They are often eccentric when they should be circular and are not found to have periods longer than 104 days even though wind accretion should still be efficient at such separa- tions. We address both these problems by introducing a kick to white dwarfs when they are born, thus solving the eccentricity problem, and.

We report observations with the Chandra X-ray Observatory of the single, cool, magnetic white dwarf GD 356.

Frequently, in accretion problems, we deal with plasmas immersed in strong magnetic fields. For neutron stars, surface fields of 1012 G (=108 T) are often met with. Many accreting white dwarfs possess magnetic fields of the order of 106–107 G (102–103. T).
