Query: The LMXB Population of NGC 3379   Presented here are the highlights from the deep Chandra observation of the
elliptical galaxy NGC 3379. From the multi-epoch observation of this galaxy,
132 discrete X-ray sources have been detected within the region overlapped by
all observations, 98 of which lie within the D25 ellipse of the galaxy. Of
these 132 sources, 71 exhibit long-term variability, indicating that they are
accreting compact objects. 11 of these sources have been identified as
transient candidates, with a further 7 possible transients. In addition to
this, from the joint Hubble/Chandra field of view, nine globular clusters (GCs)
and 53 field low mass X-ray binaries (LMXBs) have been detected in the galaxy.
Comparisons of these two populations reveals that, at higher luminosities the
field LMXBs and GC-LMXBs are similar. However, a significant lack of GC-LMXBs
has been found at lower luminosities, indicating that not all LMXBs can form in
GCs.
