Planetary Nebulae as Tracers of SMC Formation (original) (raw)

2005

Abstract

ABSTRACT In this work we obtain chemical diagrams for the Small Magellanic Cloud (SMC) using planetary nebulae (PNe) data. We collected a large number of measured spectral fluxes for a sample of SMC PNe, in order to derive accurate physical parameters and abundances. Here we present new spectral data for SMC PNe obtained between 1999 and 2002. These data are used together with all data available in the literature to improve the accuracy of the fluxes for each PN spectral line.
