NICER Discovery of Millisecond X-ray Pulsations and an Ultracompact Orbit in IGR J17494-3030

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Mason Ng, Paul S. Ray, Peter Bult, Deepto Chakrabarty, Gaurava K. Jaisawal | Summary: We report the detection of 376.05 Hz (2.66 ms) coherent X-ray pulsations in NICER observations of a transient outburst of the low-mass X-ray binary IGR J17494-3030 in 2020 October/November. The system is an […]
