Descripción
Using CGS4 on UKIRT, we have obtained the first 2.05-2.45 μm infrared
spectra of the Galactic bulge low-mass X-ray binaries (LMXBs) GX1+4 and
GX13+1. We report the detection of Brackett gamma emission from the
accretion disc in both systems, confirming the identification of the IR
counterpart to GX13+1. In addition, both spectra show CO molecular bands
and metal lines in absorption, representing the first infrared
spectroscopic detection of the secondary in a heavily obscured bulge
source. We also present a JHK spectrum of the LMXB ScoX-1, which shows
strong Hi, Hei and HeII emission.
