The case of NGC 6302: The impact of shocks in the derivation of Nitrogen abundances
P. J. A. Lago, R. D. D. Costa, M. Faúndez-Abans +1
High nitrogen abundance is characteristic of Type I planetary nebulae as well as their highly filamentary structure. In the present work we test the hypothesis of shocks as a relev…
The polar ring galaxy AM 2040-620 and its possible companion
Priscila Freitas-Lemes, Irapuan Rodrigues, Maximiliano Faúndez-Abans
Polar ring galaxies (PRGs) are peculiar systems where a gas-rich, nearly polar ring surrounds a host galaxy. They are the result of galaxy interactions that form mainly by tidal ac…
A study of the remarkable galaxy system AM 546-324 (the core of Abell S0546)
M. Faúndez-Abans, A. C. Krabbe, M. Oliveira-Abans +4
We report first results of an investigation of the tidally disturbed galaxy system AM\,546-324, whose two principal galaxies 2MFGC 04711 and AM\,0546-324 (NED02) were previously cl…
BVRI-Halpha surface photometry of peculiar ring galaxies. I. HRG 2302
M. L. M. Myrrha, L. P. R. Vaz, M. Faúndez-Abans +2
Detailed BVRI-Halpha photometry has been obtained for the ring galaxy HRG 2302. This is probably a still interacting system which shows two principal components: the target, which…
