AN ACCRETION DISK WIND AT LOW EDDINGTON RATE

According to the current paradigm, accretion onto black holes and neutron starsis associated with two types of outflows that are mutually exclusive. At >E2 ofthe Eddington limit, disk winds are detected through narrow Xray absorptionfeatures, whereas at lower massaccretion rates radio jets are seen. However,our AO1 NuSTAR observation of the neutron star lowmass Xray binary IGRJ170626143 revealed a virgul34 sigma narrow absorption line at virgul6.85 keV. Thisprovides the very first evidence that disk winds can be launched at merely virgulE3of Eddington, and may coexist with a radio jet. We propose for a 75 ks NuSTARobservation and a supporting 70 ks XMM observation to solidify this measurement,which would change our current views of inflowoutflow coupling in accreting compact objects. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
