Title Accreting pulsars in quiescence


DOI 10.5270/esa-hisou1r
Author Mr Victor Doroshenko
Description After more than 40 years of studies, surprisingly little is known on the emission of accreting pulsars at low-luminosity. It was suggested that already at 10^{35} ergs-s the onset of a centrifugal barrier should inhibit the accretion. On the other hand, pulsations during quiescence were reported for three transient pulsars, namely 1A~0535+262, 4U~1145-619, and 1A~1118-61. Accretion nature of the emission is suggested by short-term variability, energetics, hard X-ray spectrum and pulsations. It is unclear, however how the accretion proceeds in this case. Here, we propose to observe 1A~0535+262, 4U~1145-619, and 1A~1118-61 with XMM-Newton to study their spectral and timing properties to clarify the nature of pulsed emission at low luminosities.

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.
