The nature of the close magnetic white dwarf + probable brown dwarf binary SDSS
Optical time series photometry of the short period magnetic white dwarf + probable brown dwarf binary SDSS J121209.31 + 013627.7 reveals pulse-like variability in all bands from i to u, increasing towards bluer wavelengths and peaking at u. These modulations are most likely due to a self-eclipsing accretion hot spot on the white dwarf, rotating into view every 88.43 minutes. This period is comm...
متن کاملSdss J080531.84+481233.0: an Unresolved L Dwarf/t Dwarf Binary
SDSS J080531.84+481233.0 is a peculiar L-type dwarf that exhibits unusually blue near-infrared and mid-infrared colors and divergent optical (L4) and near-infrared (L9.5) spectral classifications. These peculiar spectral traits have been variously attributed to condensate cloud effects or subsolar metallicity. Here I present an improved near-infrared spectrum of this source which further demons...
متن کاملDiscovery of the Partially Eclipsing White Dwarf Binary Sdss J143547.87+373338.5 †
We have discovered a partially eclipsing white dwarf, low-mass M dwarf binary (3.015114 hour orbital period), SDSS J143547.87+373338.5, from May 2007 observations at the WIYN telescope. Here we present blue band photometry of three eclipses. Eclipse fitting gives main sequence solutions to the M dwarf companion of MS = 0.15 − 0.35M⊙ and RS = 0.17 − 0.32R⊙. Analysis of the SDSS spectrum constrai...
متن کاملLisa Astronomy of Double White Dwarf Binary Systems
The Laser Interferometer Space Antenna (LISA) will provide the largest observational sample of (interacting) double white dwarf binaries, whose evolution is driven by radiation reaction and other effects, such as tides and mass transfer. We show that, depending on the actual physical parameters of a source, LISA will be able to provide very different quality of information: for some systems LIS...
