Abundance patterns in the low-metallicity emission-line galaxies from the Early Data Release of the Sloan Digital Sky Survey
Y. I. Izotov, G. Stasinska, N. G. Guseva +1
We have derived element abundances in 310 emission-line galaxies from the Early Data Release of the Sloan Digital Sky Survey (SDSS) for which the [O {\sc iii}] 4363 emission line w…

The kinematics of the most oxygen-poor planetary nebula PN G135.9+55.9
M. G. Richer, J. A. Lopez, W. Steffen +3
PN G135.9+55.9 is a compact, high excitation nebula that has been identified recently as the most oxygen-poor halo planetary nebula. Given its very peculiar characteristics and pot…

The emission line sequence of H II galaxies
G. Stasinska, Y. Izotov
We consider 400 H II galaxies in which the oxygen abundances were obtained by electron temperature based methods. We split the sample in three metallicity bins. In each bin, a narr…
