The European X-ray Observatory Satellite (EXOSAT), originally named HELOS, was an X-ray telescope operational from May until April and in that time made observations in the X-ray band of most classes of astronomical object including active galactic nuclei, stellar coronae, cataclysmic variables, white dwarfs, X-ray binaries, clusters of galaxies, and supernova or: ESA.   Considered to be another 'classic' X-ray astronomy text book. Includes discussion of active galaxies (see Chapter 13) at a level intended for the undergraduate science major, or above. Kaufmann, William J. III, Universe, Freeman and Company, This book comes highly recommended from both students and scientists.

Cheng worked with Catalan (UK) et al. on the curtain absorption in cataclysmic variables WZ Sge, Z Cha and V Oph using HST/FOS GL observations. They found that the white dwarf spectra in all three objects are veiled by a large number of Fe II and other element features to varying strengths which they attribute to absorbing disk material. Chapters 3 and 4 cover major results from the ROSAT/WFC and Extreme Ultraviolet Explorer (EUVE) all-sky surveys, and subsequent chapters are devoted to EUVE spectroscopic observations of stellar winds, stellar coronae, white dwarfs, cataclysmic variables, active Cited by:

ROSAT observations of cataclysmic variables by Simon Robert Duck Download PDF EPUB FB2

Part of the Astrophysics and Space Science Library book series (ASSL, volume ) Abstract We studied the cataclysmic variables MV Lyr, KR Aur, and EP Dra using the ROSAT PSPC; we report on Author: Eric M. Schlegel, K. Mukai, J. Singh. Cataclysmic Variables (CVs) are well furnished laboratories in which one can investigate a number of important physical processes.

These processes include: thermonuclear reactions, nebular physics, winds, mass accretion phenomena on compact objects, magnetohydrodynamics, plasmas, thermal and non thermal radiative processes, relativistic phenomena, dust forma­ tion, etc.

Balman. In we began to consider the possibility of holding a conference on Catacysmic Variables (CVs) at Keele University.

There have been several meetings in the area of CVs recently (e. Eilat, Abano-Padova, Capetown). However as preparations for the Keele meeting progressed we realized that. From radio to TeV gamma rays, cataclysmic variables continue to provide fascinating new areas of research.

FURTHER READING: REFERENCES AND LINKS. The most comprehensive reference on CVs is Brian Warner's book Cataclysmic ROSAT observations of cataclysmic variables book Stars, Cambridge University Press, Cataclysmic Variables and Related Objects: Proceedings of the th Colloquium of the International Astronomical Union, Held at Keele, United Kingdom, The conference provided a forum to review observations from ASCA, EUVE, ROSAT, Ginga and the recently-refurbished HST.

COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.

Thus, cataclysmic variables with and without overpoweringly strong magnetic fields, and stars with densities from that found in the Sun to the degenerate matter of white dwarfs and the ultra-compact states of neutron stars and black holes are all discussed. The extensive index permits : Hardcover.

Ultraviolet observations using the Solar Blind Channel on the Hubble Space Telescope provide light curves and low-resolution spectra of three pulsating white dwarfs in the cataclysmic variables. The field of extreme ultraviolet astronomy will see two major satellite observatories to be launched inone by ESA (ROSAT mission), one by NASA (EUVE mission).

These Proceedings discuss the potential for EUV Astronomy, results from recent missions, approved and possible future missions and new developments in EUV technology.

A luminous supersoft X-ray source (SSXS, or SSS) is an astronomical source that emits only low energy (i.e., soft) X-rays have energies in the to keV range, whereas hard X-rays are in the 1–20 keV range.

SSSs emit few or no photons with energies above 1 keV, and most have effective temperature below eV. This means that the radiation they emit is highly ionizing and. "Cataclysmic variables (CVs) are close binary systems consisting of a white dwarf and a red-dwarf secondary transferring matter via the Roche lobe overflow." [39] Both fusion- and accretion-powered cataclysmic variables have been observed to be X-ray sources.
