IGR J17329-2731
From Wikipedia, the free encyclopedia
IGR J17329-2731[1] as described by European Space Agency astronomers is a single faint transient X-ray source (ATel #10644) observed with Swift/XRT on 16 August 2017 from 2:26 to 2:45 UTC with an effective exposure of time of 1 ks. It was detected within the positional uncertainty provided by INTEGRAL IBIS imagery.[2] It was described as the birth of a symbiotic X-ray binary,[1] a "first" in the lifecycle of an interacting binary star, or a zombie neutron star brought back to life by its neighboring red giant. When first described in 2017, it was seen as an X-ray flare "from an unknown source" in the direction from the galactic (Milky Way) center.[3]
