Quark Nova interpretation of the 13 keV emission feature seen in three AXPs: 1E 1048.1-5937, XTE J1810-197 and 4U 0142+61. (2014). Revista Mexicana De Astronomía Y Astrofísica, 50(2), 189-194. https://astronomia.unam.mx/journals/rmxaa/article/view/2014rmxaa..50..189k
Abstract
Three anomalous X-ray pulsars (AXPs) have significant emission lines in their burst spectra. Remarkably, the line occurs at 13 keV in all cases. This coincidence argues against the common proton-cyclotron interpretation of its origin. Previous work by Koning et al. has analysed the line using an atomic interpretation and derived constraints on the line energy and bursting environment. We build upon this work and examine the atomic interpretation in light of the quark nova model for AXPs. We find that the emission is consistent with the disk location, composition and temperature expected around AXPs in this model.Similar Articles
