Description Accretion in young, low-mass stars causes emission from X-ray to NIR
wavelengths. The UV emission component of protostellar accretion will be studied
by the HST DDT legacy program ULLYSES in a once-in-a-generation investment of
HST resources. However, most of the accretion-powered emission, including the UV
regime, is reprocessed X-ray radiation from the immediate post-shock emission.
Therefore, we propose simultaneous XMM-Newton RGS spectroscopy accompanying the
ULLYSES monitoring targets (3 stars, 5 epochs each). This will allow us, for the
first time, to directly identify physically related phenomena through their
shared variability and to decipher the physics of accretion through
line-resolved spectroscopy at X-ray and UV wavelengths.

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.
