Hughes Física, Astronomía y Matemáticas stars: mass loss radio continuum: ISM ISM: supernova remnants supernova: individual (SN 1006) We have observed the remnant of SN 1006 with high resolution and sensitivity at 1.4 GHz. These data are combined with observations performed 11 years before to measure the expansion of the radio shell. The expansion parameter , dened as R / t, is found to be 0:62 for the brightest lobes. According to theoretical models, this value appears to be compatible with ejecta interacting with a circumstellar density prole decreasing as r¿¿2, characteristic of steady presupernova mass loss. However, this could not be the case if SN 1006 is still in the ejecta-dominated evolutionary stage. 2008 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57116159054 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.33 |
