Neutron Stars Weighed by New Method

  Astronomers have used INTEGRAL and XMM-Newton to look into the neutron star in IGR J17252-3616, a highly obscured X-ray binary system. The data show how the neutron star, which is being fuelled by the stellar wind from its companion, is substantially deflecting the flow of the accreted material. Comparison with numerical simulations provides an [continue reading]
