| Description | We will observe the newly discovered gamma-ray (GR) binary LMC P3 at 3 phases of its 10.3-d orbit. LMC P3 is 4x more luminous than similar systems in gamma-rays and 10x in X-ray and radio. This extreme behavior may be driven by a large spin-down power from the suspected pulsar, as well as a high UV photon seed density of the O5 III star, but the details of the high energy emission region remain perplexing. We will probe the physical conditions of this emission region with the first high S/N phase-resolved spectra, and search for signatures of a NS or BH using the 30 microsecond time resolution of EPIC-pn in Timing mode. Our phase-resolved spectral and temporal study of LMC P3, the first extra-galactic GR binary, is the first step towards characterizing the GR binary population. |

| 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. |
