KONING, N.; LEAHY, D.  y  OUYED, R.. Atomic Interpretation of the 13 keV Emission Feature in Three AXPs: 4U 0142+61, XTE J1810-197 and 1E 1048.1-5937. Rev. mex. astron. astrofis [online]. 2013, vol.49, n.2, pp.351-356. ISSN 0185-1101.

In the past decade, three anomalous X-ray pulsars (AXPs) have shown emission features at ~13 keV in some of their burst spectra. This feature is commonly interpreted as proton-cyclotron in nature. However there are several problems with this interpretation, including the coincidence at ~13 keV in all three sources (implying the same magnetic field). In this paper we investigate the possibility that the line is atomic in origin, and the implications that this has for the environment around Anomalous X-Ray Pulsars.

Palabras llave : stars [individual (XTE J1810-197, 4U 0142+61, IE 1048.1-5937)]; stars [magnetic field]; stars [neutron].
