AGILE is an Italian Space Agency (ASI) space mission, built and operated in cooperation with INAF, INFN and CIFS, dedicated to the observation of the gamma-ray Universe in the 30 MeV - 50 GeV energy range, with simultaneous X-ray imaging capability. The AGILE satellite, launched on April 23rd, 2007, is substantially contributing to improve our knowledge on gamma-ray sources. I will...
31. Optical companions to binary Millisecond Pulsars in Globular Clusters: the case of IGR J18245-2452/PSR J1824-2452I
3/27/14, 4:30 PM
The identification of the optical companions to binary millisecond pulsars (MSPs) is fundamental to characterize the formation and evolutionary processes of these exotic objects and to constrain the neutron star mass. In Globular Clusters (GCs) it also represents a crucial tool for quantifying the occurrence of dynamical interactions and understanding the effects of high stellar...

4U 1636-536 is a well-studied LMXB, consisting of a neutron star in a 3.8 hr orbit with a companion star of about 0.4 solar mass. The X-ray source shows the full range of rapid time variability, among them, burst oscillations and mHz QPOs are associated with thermonuclear burning on the neutron star. We performed a variability study of archival broadband X-ray observations of 4U 1636-536 and...

Intense X-ray bursts (type-I bursts), originating from unstable thermonuclear conflagration, are observed from the surfaces of many accreting neutron star Low Mass X-ray Binary (LMXB) systems and are useful tools to constrain the equation of state and probe strong gravity regime. A series of such X-ray bursts were observed during the 2010 outburst of the transient pulsar IGR J17480-2446. These...
