Chemical evolution of the Small Magellanic Cloud based on planetary nebulae
T. P. Idiart, W. J. Maciel, R. D. D. Costa
We investigate the chemical evolution of the Small Magellanic Cloud (SMC) based on abundance data of planetary nebulae (PNe). The main goal is to investigate the time evolution of…
Evolution from AGB to planetary nebula in the MSX survey
R. Ortiz, S. Lorenz-Martins, W. J. Maciel +1
We investigate the evolution of oxygen- and carbon-rich AGB stars, post-AGB objects, and planetary nebulae using data collected mainly from the MSX catalogue. Magnitudes and colour…
Chemical enrichment and star formation in the Milky Way disk; II. Star formation history
H. J. Rocha-Pinto, John Scalo, W. J. Maciel +1
A chromospheric age distribution of 552 late-type dwarfs is transformed into a star formation history by the application of scale height corrections, stellar evolutionary correctio…
