Title: Winds and jets in GX13+1: a multi-wavelength campaign
Abstract: Studies of disk winds and jets in LMXBs with luminosities up to about 20% Eddington suggest that these types of outflows are to a large extent mutually exclusive. However, in a recent study of near- and super-Eddington LMXBs we found four sources that show evidence that, at high luminosities, jets and winds may be launched simultaneously. We have organized a Chandra multi-wavelength campaign of one of these sources, the neutron star LMXB GX 13+1. With four simultaneous Chandra, JVLA, and (approved) NICER observations we will investigate if jets and winds can indeed co-exist in GX 13+1 and, if so, how their strengths relate to each other and the various X-ray spectral components. Additional near-infrared spectroscopy (Gemini South) is requested to investigate the acceleration of winds at large radii.
