The homogeneity of chemical abundances in H II regions of the Magellanic Clouds
G. Domínguez-Guzmán, M. Rodríguez, J. García-Rojas +3
We use very deep spectra obtained with the Ultraviolet-Visual Echelle Spectrograph at the Very Large Telescope to derive physical conditions and chemical abundances of four H II re…
Chemical abundances and temperature structure of H II regions
G. Domínguez-Guzmán, M. Rodríguez, C. Esteban +1
We use a sample of 37 H II regions with high quality spectra to study the behavior of the relative abundances of several elements as a function of metallicity. The sample includes…
Carbon and oxygen in HII regions of the Magellanic Clouds: abundance discrepancy and chemical evolution
L. Toribio San Cipriano, G. Domínguez-Guzmán, C. Esteban +5
We present C and O abundances in the Magellanic Clouds derived from deep spectra of HII regions. The data have been taken with the Ultraviolet-Visual Echelle Spectrograph at the 8.…
The oxygen abundance gradient in M81 and the robustness of abundance determinations in H II regions
K. Z. Arellano-Córdova, M. Rodríguez, Y. D. Mayya +1
We study the sensitivity of the methods available for abundance determinations in H II regions to potential observational problems. We compare the dispersions they introduce around…
A new Planetary Nebula in the outer reaches of the Galaxy
K. Viironen, A. Mampaso, R. L. M. Corradi +11
A proper determination of the abundance gradient in the Milky Way requires the observation of objects at large galactiocentric distances. With this aim, we are exploring the planet…
Candidate planetary nebulae in the IPHAS photometric catalogue
K. Viironen, R. Greimel, R. L. M. Corradi +12
Context. We have carried out a semi-automated search for planetary nebulae (PNe) in the INT Photometric H-Alpha Survey (IPHAS) catalogue. We present the PN search and the list of s…
