    > As I know of, an up-to-date list of SSXS is given by J. Greiner (Catalog > of Luminous Supersoft X-Ray Sources, P of Supersoft X-Ray Sources, > Ed. J. Greiner, , Springer). Is there any newer list? Thank you very much for the information. I have once looked (but not read ;-) this book . Luminous supersoft X-ray sources were discovered with the Einstein observatory and have been established as an important new class of X-ray binaries on the basis of observations with the Roentgen Satellite (ROSAT). They have extremely soft spectra (equivalent blackbody temperatures of ∼15–80 eV) and are highly luminous (bolometric luminosities of 10–10 erg s). Correcting for the heavy Cited by:

    Topics covered include binary systems, gamma ray burst sources, anomalous X-ray pulsars, super-soft sources, and enigmatic fast X-ray transients. Further chapters are dedicated to isolated neutron stars and the X-ray source populations of globular clusters. A small number of "supersoft" X-ray sources has been found in the direction of the Large Magellanic Cloud (LMC), although information has been published for only six of these. It has been suggested.

Optical follow-up observations have revealed the binary nature of several of them. Observations with X-ray satellite ROSAT over the past 5 years have established supersoft X-ray sources as a new class of objects in our Galaxy and beyond.

Optical follow-up observations have revealed the binary nature of several of them. The study of thousands of supersoft x-ray sources in a wide range of galactic environments has allowed us to establish the statistics of the class while at the same time identifying its most extreme and intriguing members.

Catalog of Supersoft X-ray Sources. After the discovery of supersoft X-ray sources with Einstein Observatory observations, the ROSAT satellite with its PSPC detector has discovered about four dozen new supersoft sources and has thus established luminous supersoft X-ray sources (SSS) as a new class of by: We present new X-ray data with an improved position for the supersoft X-ray source RXJ–, and propose a candidate for the optical identification.

The source was initially designated as RXJ– because there was a high uncertainty in the position, at the edge of the field of the ROSAT PSPC (Orio & Ögelman ).

More than supersoft X-ray sources (SSS) are reported in ∼20 external galaxies, the Magellanic Clouds (MCs) and our Galaxy.

The effective temperatures of the brighter SSS are ∼20– eV. SSS with luminosities below ≈3 × 10 38 erg s −1 are consistent with accreting white dwarfs (WDs) with steady nuclear burning or by: A Systematic Search for Supersoft X-Ray Sources in the ROSAT All-Sky Survey J.

binary supersoft X-ray sources (SSSs), observed to have temperatures of a few×K and luminosities on the order of erg/s. These and other types of SSSs are expected to be capable of ionizing their surrounding circumstellar medium; however, to date only one such nebula was detected in the Large Magellanic Cloud (of its 6 known close.

A luminous supersoft X-ray source (SSXS, or SSS) is an astronomical source that emits only low energy (i.e., soft) X-rays. 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 is. Summary: Observations with the X-ray satellite ROSAT have established supersoft X-ray sources as a new class of objects in our galaxy and beyond.

This work provides an overview of the recent observational discoveries, and describes relations between supersoft sources.

At these soft energies, the HRI count rates are typically a factor of smaller than those of the PSPC (David et al. Greiner et al. Sincesome of the brightest supersoft X-ray sources have been also observed with the low-energy concentrator spectrometer (LECS) onboard BeppoSAX. Modern Diagnostic X-ray Sources: Technology, Manufacturing, Reliability gives an up-to-date summary of X-ray source design for applications in modern diagnostic medical imaging.

The book begins with a historical overCited by: ROSAT source, RX J, is optically bright and “off” in X-rays for the days of a recurrent cycle, then it undergoes a rapid transition in less than 4 days to the supersoft X-ray source stage, with decreased optical luminosity.

This stage lasts for about a month. The prototype supersoft x‐ray source (SSS) is the well‐known x‐ray binary CAL83 in the LMC, which has an orbital period of : Gunther Hasinger.

Abstract: Following their discovery by the Einstein satellite, supersoft X-ray sources (SSXS) are presently con- sidered to be an important new class of X-ray binaries, with characteristic X-ray luminosities ˘10 38 erg s 1 and spectral peaks occuring in 15–80 eV.

More than SSXS have been discovered so far in the Milky Way, theAuthor: Parag Bhattacharya. In some luminous supersoft X-ray sources, hydrogen accretes onto the surface of a white dwarf at rates more-or-less compatible with steady nuclear burning. The white dwarfs in these systems therefore have a good chance to grow in mass.

Here we review what is known about the rate of Type Ia supernovae that may be associated with by: 6. Luminous supersoft X-ray sources.

Luminous super soft X-ray sources have a characteristic blackbody temperature of a few tens of eV (~ eV) and a bolometric luminosity of ~10 38 erg/s (below ~ 3 x 10 38 erg/s).

Apparently, luminous SSSs can have equivalent blackbody temperatures as low as ~15 eV and luminosities ranging from 10 36 to 10 38 erg/s. The numbers of luminous SSSs in the disks.
