Infrared identification of 4U1323-619 revisited

Abstract

We re-examine the infrared counterpart of the dipping low-mass X-ray binary 4U1323-619. New X-ray data available from the XMM and Chandra observatories combined with archival infrared observations from the European Southern Observatory 3.6-m New Technology Telescope allow us to define a new possible counterpart. We present here its photometric properties and compare them with a simple analytical model of an accretion disc illuminated by a hot central corona.
