Probing the disc-jet coupling in the neutron star binary Sco X-1
Abstract
Sco X-1 is the brightest X-ray source in the sky. Located 2.8 kpc away, Sco X-1 is a well-established persistent Z-source, and one of the few neutron star binaries where extended radio jets have been resolved at milliarcseconds scales. We propose to observe Sco X-1 with Chandra ACIS-S/HETG for 120ks (not necessarily uninterrupted), to form the primary X-ray coverage for our campaign, overlapping with a 72-hr continuous Global VLBI radio monitoring observation (proposed for in February 2018). We aim to unveil the link between specific accretion events (state transitions and/or QPOs) and the launch of transient outflows, and to improve our understanding of ultra-relativistic outflows from neutron stars and of the conditions underlying their production.
