On the discovery of an enormous ionized halo around the hot DO white dwarf PG 1034 + 001
Very recently, the discovery of the largest known planetary nebula on the sky surrounding the DO white dwarf PG 1034+001 with an apparent diameter of about 2 • , corresponding to a linear diameter of 3.5-7.0 pc at the likely distance of 100-200 pc, has been reported by Hewett et al. (2003). A careful inspection of available sky survey data has now shown that this planetary nebula, Hewett 1, is ...
متن کاملDiscovery of an Ultracool White Dwarf Companion
The discovery of a low luminosity common proper motion companion to the white dwarf GD392 at a wide separation of 46 is reported. BV RIJHK photometry strongly indicates suppressed flux at all near infrared wavelengths. Thus, GD392B is one of the few white dwarfs to show collision-induced absorption due to the presence of photospheric H2 and the first ultracool white dwarf detected as a companio...
متن کاملThe Nebular Environment and Enigmatic Hard X - ray Emission of the Hot DO White Dwarf KPD 0005 + 5106
We have detected an ionized nebula around the hot DO white dwarf KPD0005+5106, and used the [O III]/Hα ratios and nebular velocities to separate this nebula from the background H II region of AO Cas. The angular size of the [O III] nebula of KPD0005+5106 is∼ 3. The velocity of this nebula is similar to those of the local interstellar H I gas and the interstellar/circumstellar absorption lines i...
متن کاملA new period for the magnetic white dwarf KPD 0253 + 5052
We present phaseresolved circular polarization measurements of the rotating magnetic white dwarf KPD 0253+5052. A new and more accurate period of (3.79 ± 0.05) h for KPD 0253+5052 could be determined by measuring the broadband polarization in the Hβ and Hγ lines derived from medium resolution (about 5 ˚ A FWHM) spectropolarimetric data at different phases.
متن کاملThe Dust cloud around the White Dwarf G 29 - 38
We present new observations of the white dwarf G 29-38 with the camera (4.5 and 8 μm), photometer (24 μm), and spectrograph (5.5–14 μm) of the Spitzer Space Telescope. This star has an exceptionally large infrared excess amounting to 3% of the bolometric luminosity. The spectral energy distribution has a continuum peak around 4.5 μm and a 9–11 μm emission feature 1.25 times brighter than the co...
