The new class of super soft X-ray sources (SSS) and the Galactic foreground stars emerge yellow or red. The nearly five million-degree interstellar gas in the LMC is manifested by the diffuse green emission. SSS are thought to be white dwarfs accreting matter from a binary companion star with a rate sufficient to produce steady nuclear burning on the white dwarf surface. In contrast to other accreting X-ray binaries, where the gravitational potential energy powers the X-ray source, nuclear burning is the primary energy source in SSS. |
The ROSAT survey of a 13.5° × 15.5° region in the Large Magellanic Cloud. Here, the energy picture is given. 516 X-ray sources were discovered. |
