Spectroscopy of a Neutron Star Transient in Outburst
Abstract
Neutron star X-ray transients span a broad range of stellar magnetic fields and spin periods, and their outbursts can span five orders of magnitude in mass accretion rate. They are excellent settings in which to study basic disk physics through X-ray disk winds, and the evolution of disks and accretion flows with mass accretion rate. New observations can also confirm the nature of relativistic disk lines, and exploit such lines to constrain the stellar radius, the equation of state, and even the stellar magnetic field strength. Persistent neutron star binaries represent a rich discovery space. We request 2 40 ksec observations to study a new or known neutron star transient in outburst.
