SIMULTANEOUS SPECTRAL AND TIMING OBSERVATIONS OF ACCRETING NEUTRON STARS


ABSTRACT

We propose to use ACSA together with RXTE to conduct simultaneous spectral and fast timing observations of neutron star low-mass x-ray binaries. Joint spectral and timing data should lead to important new information on the behavior of accretion flows in neutron star low-mass x-ray binaries.
