An X-ray Flare from eta Carinae as seen by NICER
Abstract
Monitoring of the 2-10 keV colliding emission X-ray spectrum of the extremely massive colliding wind binary eta Carinae by the Neutron Star Interior Composition Explorer (NICER) shows that the system is undergoing an X-ray flare, similar to those strong X-ray variations seen in other orbital cycles near this orbital phase (Moffat & Corcoran 2009, ApJ 707, 693).
