Description We propose to study the evolution of the 0.5-10keV spectrum and pulse profile of
Her X-1 in order to resolve the properties of the photo ionized accretion disk
atmosphere of Her X-1 as the outer rim of the warped accretion disk frees our
line of sight onto the neutron star. The proposed campaign consists of five 10ks
observations that cover the 2.5d of one turn on of the main on state of the 35d
cycle. The observations will be spaced 0.5d apart and cover the whole turn on
from quiescence to almost the peak of the main on.

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.
