Title The Dark Side Exposed: Hidden Neutron Stars and Black Holes in Hot sdB Binaries


DOI 10.5270/esa-9dkmg0o
Author Mr Stephan Geier
Description A large number of dormant black hole binaries is predicted to exist in the Galaxy. We propose observations of a small sample of recently discovered binaries where the optical analysis shows the presence of a compact object with a mass exceeding 3 solar masses. Accretion from the weak wind of the stellar companion is predicted to result in detectable X-rays, which would prove the existence of a black hole in these systems.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
