The Accretion Process in Neutron-star Low-mass X-ray Binaries

There are several long-standing problems regarding the spectral study of neutron-star low-mass X-ray binaries (NS LMXBs) : how to decompose their spectra, how different subclasses are related, and what cause the spectral evolution for each subclass. Using thousands of RXTE observations, we have obtained a new way to decompose spectra from neutron-star low-mass X-ray binaries (NS LMXBs), which lead to very different but physically more reasonable interpretations than classical models. With a legendary new NS transient, XTE J1701-462, we are finally able to reveal the direct relation between different subclasses of NS LMXBs and understand the physical cause of their spectral evolution.
