New white dwarf stars in the Sloan Digital Sky Survey Data Release 10
S. O. Kepler, Ingrid Pelisoli, Detlev Koester +11
We report the discovery of 9 089 new spectroscopically confirmed white dwarfs and subdwarfs in the Sloan Digital Sky Survey Data Release 10. We obtain Teff, log g and mass for hydr…
Component masses of young, wide, non-magnetic white dwarf binaries in the SDSS DR7
R. B. Baxter, P. D. Dobbie, Q. A. Parker +7
We present a spectroscopic component analysis of 18 candidate young, wide, non-magnetic, double-degenerate binaries identified from a search of the Sloan Digital Sky Survey Data Re…
A white dwarf merger as progenitor of the anomalous X-ray pulsar 4U 0142+61?
J. A. Rueda, K. Boshkayev, L. Izzo +5
It has been recently proposed that massive fast-rotating highly-magnetized white dwarfs could describe the observational properties of some of Soft Gamma-Ray Repeaters (SGRs) and A…
The progenitors of magnetic white dwarfs in open clusters
B. Külebi, J. Kalirai, S. Jordan +1
According to the fossil-field hypothesis magnetic fields are remnants of the previous stages of evolution. However, population synthesis calculations are unable to reproduce the ma…
Magnetic white dwarfs with debris discs
Baybars Külebi, K. Yavuz Ekşi, Pablo Lorén-Aguilar +2
It has long been accepted that a possible mechanism for explaining the existence of magnetic white dwarfs is the merger of a binary white dwarf system, as there are viable mechanis…
Magnetic White Dwarf Stars in the Sloan Digital Sky Survey
S. O. Kepler, Ingrid Pelisoli, Stefan Jordan +10
To obtain a better statistics on the occurrence of magnetism among white dwarfs, we searched the spectra of the hydrogen atmosphere white dwarf stars (DAs) in the Data Release 7 of…
