| Abstract | We have identified a possible candidate transitional millisecond pulsar (tMSP)in the globular cluster Terzan 6. It shows type-I X-ray bursts, eclipses, andusually has X-ray luminosities of (1.3-60)e33 erg/s. The X-ray/radio behavior ofthe source suggests it may be a tMSPs or an accreting millisecond X-ray pulsar(AMXP). During a rare outburst state ($>$1e36 erg/s) we observed indications forX-ray pulsations at 463.5 Hz, strengthening the case for a tMSP/AMXPinterpretation. We propose a 120 ks XMM ToO observation to constrain the orbitalperiod of the source, confirm the presence of pulsations, and search forsub-luminous disk state behavior (only seen in tMSPs). With our observation wewill determine whether the source can be considered a strong candidate tMSP or a regular AMXP. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
