Hot white dwarfs are objects that copiously emit in the Extreme Ultraviolet and soft X-ray range. They are the brightest sources seen in the Low Energy Telescope of EXOSAT, with countrates up to 25 cnts/s. in contrast to their optical and UV spectrum the total flux and spectral distribution at soft X-ray energies are highly sensitive to the effective temperature, structure and elemental composition of the dwarf's atmosphere. The imaging soft X-ray experiments onboard EXOSAT cover with large… 
White dwarfs as the maximal soft x-ray scatterers
In this paper, we explore the effect of density on the structure formation and the electromagnetic wave (EMw) elastic scattering on quantum plasmas, using the generalized quantum hydrodynamic model
Spectropolarimetric follow-up of 8 rapidly rotating, X-ray bright FK Comae candidates
Our understanding of the evolved, rapidly rotating, magnetically active, and apparently single FK Comae stars is significantly hindered by their extreme rarity: only two stars in addition to FK Com
The existence of “radio-weak BL Lac objects” (RWBLs) has been an open question, and has remained unsolved since the discovery that quasars could be radio-quiet or radio-loud. Recently, several groups
X-ray photolysis of CH3COCH3 ice: implications for the radiation effects of compact objects towards astrophysical ices
In this study, we employed broadband X-rays ($6-2000$ eV) to irradiate the frozen acetone CH$_3$COCH$_3$, at the temperature of 12 K, with different photon fluences up to $2.7\times 10^{18}$ photons


Photospheric soft X-ray emission from hot DA white dwarfs
The Einstein Observatory's imaging proportional counter has detected 150-eV soft X-ray radiation from the four hot DA white dwarfs EG 187, Gr 288 and 289, and LB 1663. The observed pulse height
The soft X-ray spectrum of Sirius B - Evidence for the photospheric hypothesis
The soft X-ray spectrum of Sirius obtained by the HEAO 1 A-2 experiment is used to investigate the origin of the X-radiation from that system. It is shown that, if the emission is coronal, then the
Detection of X-ray emission from stellar coronae with ANS
With the soft X-ray detector aboard the Astronomical Netherlands Satellite (ANS) we have searched for soft X-ray emission in the range 0.2--0.284 keV from hot stellar coronae. X-ray emission has been
Results from an extensive Einstein stellar survey.
We report the preliminary results of the Einstein Observatory stellar X-ray survey. To date, 143 soft X-ray sources have been identified with stellar counterparts, leaving no doubt that stars in
Extreme-ultraviolet spectrophotometry of the hot DA white dwarf HZ 43: detection of He II in the stellar atmosphere
ae report a spectrum of the hot white dwarf HZ 43 in the extreme ultraviolet band from 170--500 A with a resolution of 15 A. The spectrum is marked by a prominent absorption edge at 225 A +- 15 A
The atmosphere of Sirius B. II - Extreme-ultraviolet observations
The letter reports an observation of Sirius in the extreme-ultraviolet (100-1000 A) band, using a grazing-incidence telescope flown aboard the Apollo-Soyuz mission. No positive flux is detected;
Discovery of a nonsolar extreme-ultraviolet source
Results are reported for observations of EUV emission from an extrasolar object which were made with a grazing-incidence telescope during the Apollo-Soyuz mission. The total energy flux in the
Diffusion time scales in white dwarfs
The time scales of a few representative elements diffusion in hydrogen- and helium-rich white-dwarf envelopes are presented. The dependences on depth, the stellar mass, and effective temperature are
Constraints on the corona model for Sirius B
SINCE the discovery of Sirius as a soft X-ray source1, two models have been proposed to account for the emission—thermal emission from deep layers of an almost pure hydrogen atmosphere2, and an
An ultrasoft X-ray source in Coma Berenices
We have observed an intense soft X-ray source with an extraordinary spectrum in Coma Berenices, 4$sup 0$ northeast of and unassociated with the Coma cluster of galaxies. Two spectra, obtained at
