| Description | The study of both early and late stages of stellar evolution benefits from investigations of stars orbited by dusty disks, as identified via thermal infrared excesses above photospheric emission. Distinguishing between two very different possibilities for the presence of such a disk --- star (and planet) birth vs. death --- can be surprisingly problematic in certain cases. One such case is RZ Psc. For decades the evolutionary status of this infrared-bright, variable (anti-flare) star has been ambiguous; both pre- and post-main sequence models have been offered. We propose XMM observations that will supply an important datum to break this evolutionary degeneracy. |

| 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. |
