"Counterpart" method for abundance determinations in HII regions
Leonid S. Pilyugin, Eva K. Grebel, Lars Mattsson
We suggest a new way of the determining abundances and electron temperatures in HII regions from strong emission lines. Our approach is based on the standard assumption that HII re…
Oxygen and nitrogen abundances of HII regions in six spiral galaxies
Alexander S. Gusev, Leonid S. Pilyugin, Firouz Sakhibov +3
Spectroscopic observations of 63 HII regions in six spiral galaxies (NGC 628, NGC 783, NGC 2336, NGC 6217, NGC 7331, and NGC 7678) were carried out with the 6-meter telescope (BTA)…
Abundance determination from global emission-line SDSS spectra: exploring objects with high N/O ratios
L. S. Pilyugin, J. M. Vilchez, L. Mattsson +1
We have compared the oxygen and nitrogen abundances derived from global emission-line SDSS spectra of galaxies using (1) the Te method and (2) two recent strong line calibrations:…
