Magnetic White Dwarfs: Observations, Theory, and Future Prospects
Enrique García-Berro, Mukremin Kilic, S. O. Kepler
Isolated magnetic white dwarfs have field strengths ranging from kilogauss to gigagauss, and constitute an interesting class of objects. The origin of the magnetic field is still t…
New white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12
S. O. Kepler, Ingrid Pelisoli, Detlev Koester +7
We report the discovery of 6576 new spectroscopically confirmed white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12. We obtain Teff, log g and mass for h…
DB white dwarfs in the Sloan Digital Sky Survey Data Release 10 and 12
Detlev Koester, S. O. Kepler
White dwarfs with helium-dominated atmospheres comprise approximately 20% of all white dwarfs. Among the open questions are the total masses and the origin of the hydrogen traces o…
The age-metallicity dependence for white dwarfs
A. D. Romero, F. Campos, S. O. Kepler
We present a theoretical study on the metallicity dependence of the initialtofinal mass relation and its influence on white dwarf age determinations. We compute a grid of evo…
Extracting parameters from Colour-Magnitude Diagrams
C. Bonatto, F. Campos, S. O. Kepler +1
We present a simple approach for obtaining robust values of astrophysical parameters from the observed colour-magnitude diagrams (CMDs) of star clusters. The basic inputs are the H…
