This paper gives an overview of the properties of the observed X-ray spectra of low-mass X-ray binaries containing a neutron star (neutron-star LMXBs) and those of X-ray binaries containing a black hole (black-hole XBs). The X-ray spectra of these systems change their characteristics with the mass accretion rate. At high X-ray luminosities, typically Lx>1037 erg sec−1, soft thermal emission from the accretion disk dominates. There is a distinct difference in the X-ray spectrum between neutron-star LMXBs and black-hole XBs. When the luminosity decreases below a certain level (Lx∼1037 erg sec−1), the X-ray spectra of both systems undergo a transition to a hard power-law form. At further low luminosities (Lx<1033-32 erg sec−1), the spectra become very soft. The characteristics of these X-ray spectra at different X-ray luminosities (different accretion rates) are described and the implications are discussed. [ABSTRACT FROM AUTHOR]
