Title Anticipated ToO of pre-main sequence star undergoing an optical-IR outburst

Author Dr Nicolas Grosso
Description We propose a 32 ks EPIC ToO to observe any new optical-IR outburst from a PMS star. The proposed observations will yield the contributions of soft X-ray emission due to shocks in accretion streams or jets versus harder X-rays from star-disk magnetic reconnection activity during the eruption, as well as the degree of X-ray variability on a timescale of hours. These results will be compared with those obtained for the recent outbursts of, e.g., V1647 Ori and EX Lup, so as to begin to establish the dependence of the X-ray characteristics of PMS star eruptions on, e.g., PMS accretion rate and evolutionary state.

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.
