Infrared identification of 4U1323-619 revisited

TL;DR

This paper re-evaluates the infrared counterpart of the low-mass X-ray binary 4U1323-619 using new X-ray and archival IR data, proposing a refined identification and analyzing its properties with a simple accretion disc model.

Contribution

It provides a new possible infrared counterpart for 4U1323-619 and compares its photometric data with an analytical accretion disc illumination model.

Findings

Identified a new potential infrared counterpart.

Compared photometric data with a disc illumination model.

Enhanced understanding of the system's infrared properties.

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 IR observations from the ESO 3.6m 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 the hot central corona known to be present in the binary system.
