White dwarfs catalogue

    Hi

    I've solved numerically the equations for a white dwarf (ie, a newtonian star in hydrostatic equilibrium, supposing the pressure is caused by relativistic electrons and the mass is provided by nuclei).

    I would like to plot observed radius and mass for testing this model. Do you know if there is a catalogue with this experimental data of white dwarfs?

    Thank you for your time :)

    Greetings!

    Hello

    Thanks for answering so quickly. I didn't find the radius of the WD in these web pages.

    And thank you for your advice, but I googled during a whole day without results. The mass is easy to find, but the radius...

    Greetings!

    The relationship between the radius and the mass of a white dwarf is a simple one:

    http://en.wikipedia.org/wiki/White_dwarf {See the section Mass–radius relationship and mass limit }

    The paper cited here:

    http://adsabs.harvard.edu/abs/1979ApJ...228..240S

    compiles a table of the characteristics of over 100 WD stars. Part 2 of the paper contains a table of this data, and a pdf copy of the paper can be downloaded from a link contained in the abstract.

    Hello!

    Thank you both!

    Wow, almost 1900 WD catalogue!! :D

    Thank you, it's a good reference and there is a lot of information! :D

    Greetings!
