- Radial dependence of extinction in parent galaxies of supernovae B. Arbutina D. Urosevic D. Onic Física, Astronomía y Matemáticas ISM: dust extinction galaxies: spiral supernovae: general The problem of extinction is the most important issue to be dealt with in theprocess of obtaining true absolute magnitudes of core-collapse (including stripped-envelope) supernovae (SNe). The plane-parallel model, widely used in the past, wasshown not to describe extinction adequately. We try to apply an alternative modelwhich introduces radial dependance of extinction in parent galaxies of supernovae.For calculating extinction in our Galaxy we use two different methods and com-pare the results obtained. Our analysis is primarily focused on a chosen sample ofstripped-envelope SNe (Ib/c) for which we find intrinsic peak absolute magnitudeM0B = -17.80 ± 0.43. 2008 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57144107 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) Num.1 Vol.44
