Discovery of a bright eclipsing cataclysmic variable
D. K. Sing, E. M. Green, S. B. Howell +4
We report on the discovery of J0644+3344, a bright deeply eclipsing cataclysmic variable (CV) binary. Spectral signatures of both binary components and an accretion disk can be see…
Spectropolarimetric Survey of Hydrogen-rich White Dwarf Stars
A. Kawka, S. Vennes, G. D. Schmidt +2
We have conducted a survey of 61 southern white dwarfs searching for magnetic fields using Zeeman spectropolarimetry. Our objective is to obtain a magnetic field distribution for t…
Model Atmosphere Analysis of the Weakly Magnetic DZ White Dwarf G165-7
P. Dufour, P. Bergeron, G. D. Schmidt +5
A reanalysis of the strongly metal-blanketed DZ white dwarf G165-7 is presented. An improved grid of model atmospheres and synthetic spectra is used to analyze BVRI, JHK, and ugriz…
XMM-Newton Observations of the Extremely Low Accretion Rate Polars SDSSJ15531.12+551614.5 and SDSSJ132411.57+032050.5
Paula Szkody, Lee Homer, Bing Chen +6
XMM-Newton observations of the polar SDSSJ155331.12+551614.5 reveal that all the X-ray flux emerges at energies less than 2 keV. The best fit to the spectrum is with a thermal plas…
Observations of the Magnetic Cataclysmic Variable VV Puppis with the Far Ultraviolet Spectroscopic Explorer
D. W. Hoard, P. Szkody, R. Ishioka +5
We present the first far-ultraviolet (FUV) observations of the magnetic cataclysmic variable VV Puppis, obtained with the Far Ultraviolet Spectroscopic Explorer satellite. In addit…
Optical/Infrared spectroscopy and photometry of the short period binary RX J1914+24
G. Ramsay, K. Wu, M. Cropper +4
We present observations of the proposed double degenerate polar RX J1914+24. Our optical and infrared spectra show no emission lines. This, coupled with the lack of significant lev…
Studies of Magnetic and Suspected-Magnetic Southern White Dwarfs
G. D. Schmidt, S. Vennes, D. T. Wickramasinghe +1
Optical spectrophotometry and circular spectropolarimetry are presented for several candidate magnetic white dwarfs that were identified during the Hamburg/ESO survey for bright QS…
Discovery of a Magnetic DZ White Dwarf with Zeeman-Split Lines of Heavy Elements
I. Neill Reid, James Liebert, Gary D. Schmidt
A spectroscopic survey of previously-unstudied Luyten Half Second proper motion stars has resulted in the discoveries of two new cool magnetic white dwarfs. One (LHS 2273) is a rou…
Probing the Geometry and Circumstellar Environment of SN 1993J in M81
Hien D. Tran, Alexei V. Filippenko, Gary D. Schmidt +3
We have monitored the polarized radiation of the Type IIb SN 1993J in M81 over a period of 41 days, starting from 7 days after the explosion on 1993 March 27.5 (UT). Our data show…
