NICER observation list: Target ID 460101

Abstract

The source 47 Tuc X-9 is an ultracompact X-ray binary, and is one of the best candidate globular cluster black holes in the Milky Way. It shows a strong modulation with a characteristic timescale of about 1 week. If this variation is shown to be strictly periodic, it would favor neutron star models which are otherwise disfavored by the existing data. We propose monitoring this object to determine whether this long term variability is red noise or periodic.
