Metallicity gradients in M31, M33, NGC 300 and the Milky Way using abundances of different elements
Miriam Peña, Sheila N. Flores-Durán
Metallicity gradients derived from planetary nebulae (PNe) using O, Ne, and Ar abundances are studied and compared to those from HII regions in the galaxies M31, M33, NGC 300 and t…
The PNe and H II regions in NGC 6822 revisited. Clues to AGB nucleosynthesis
Jorge García-Rojas, Miriam Peña, Sheila Flores-Durán +1
(Abridged) The chemical behaviour of an ample sample of PNe in NGC6822 is analyzed. Spectrophotometric data of 11 PNe and two H II regions were obtained with the OSIRIS spectrograp…
Kinematic study of planetary nebulae in NGC 6822
S. N. Flores-Durán, M. Peña, L. Hernández-Martínez +2
By measuring precise radial velocities of planetary nebulae (which belong to the intermediate age population), H II regions, and A-type supergiant stars (which are members of the y…
