| Description | EXORs are extreme T Tauri stars that experience major UV-optical eruptions (3-5 mag) that last about a year. These recurring outbursts driven by high accretion rates assist in dispersal of the circumstellar disk and the large X-ray-UV flux injected into the local environment modifies the physical and chemical history, influencing planet formation and time scales. Little X-ray data exists on these stars during either quiescent or outburst phases, so basic details such as how much X-ray flux is produced during eruption is unknown. We will characterize the X-ray properties of 7 EXOR, while ground-based monitoring will determine what state the EXORs are in at the time of the XMM observtaions. |

| 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. |
