Description The ADAF model for stellar-mass Galactic black holes makes a specific prediction: at fractional Eddington mass accretion rates below 0.08, the inner edge of the accretion disk should be truncated at appx. 1 E+4 Schwarzschild radii. Disks truncated at such radii should not be visible in X-rays, as viscous heating is small when the disk is not very deep in the gravitational potential. We request 270 ksec of goodtime to observe GX 339-4 in quiescence with XMM-Newton, to rigorously test the truncated disk prediction at an m-dot-Edd. of 3 E-5 by searching for a disk component in the X-ray spectrum. We will support this observation with IR (Magellan) and radio (ATCA) monitoring observation.

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.
