On the Origin of Spectral Features Observed during Thermonuclear X-ray Bursts and in the Aftermath Emission of a Long Burst from 4U 1820-30

Gaurava K. Jaisawal, Jérôme Chenevez, Tod E. Strohmayer +6

We study 15 thermonuclear X-ray bursts from 4U 1820--30 observed with the Neutron Star Interior Composition Explorer (NICER). We find evidence of a narrow emission line at 1.0 keV…
