- Dust particles on a photon diet in V605 AQl J. Koller Física, Astronomía y Matemáticas DUST EXTINCTION METHODS: NUMERICAL CIRCUMSTELLAR MATTER PLANETARY NEBULAE: INDIVIDUAL (V605 AQL) We present a new model to explain the excess in mid and near infrared emission of V605 Aql. This hydrogenpoor object is of special interest because it formed after a late helium ash of the central star in the planetarynebula Abell 58. Simple grain size models with an equilibrium dust temperature cannot explain ISO and IRASmeasurements. Environmental condition and grain parameters are discussed to extend standard models withtemperature uctuations and a grain size distribution. 2002 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57112063 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.12
