- A Possible Conection Between Magnetars and Gamma-Ray Bursts J. E. Horvath M. P. Allen J. A. Pacheco de Freitas Física, Astronomía y Matemáticas We argue that magnetars, neutron stars with strong magnetic fields, can be the powerhouses behind some gamma-ray bursts (GRBs), thanks to effects only possible in presence of high magnetic fields. The production of axions in supernova cores by pair anihilation e+e- -> a is possible in such intense magnetic fields. A fraction of the ~ 1053 erg of binding energy of the newly created neutron star escapes with this axion flux. However, axions in high magnetic fields decay through a -> e+e- with mean life tau ~ 10-4 s, therefore close to the magnetar, producing the relativistic shock with ~ 1051 erg ("fireball") and the GRB. At least one GRB was coincident with an "anomalous" supernova Ic, supporting this scenario. 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101113 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.11
