Checking the reliability of equivalent width R23 for estimating metallicities of galaxies
Y. C. Liang, F. Hammer, S. Y. Yin
We verify whether the O/H abundances of galaxies can be derived from the equivalent width (EW) R23 instead of the extinction-corrected flux R23, and eventually propose a method of…

The direct oxygen abundances of metal-rich galaxies derived from electron temperature
Y. C. Liang, F. Hammer, S. Y. Yin +3
We aim to derive the electron temperature Te in the gas of metal-rich star-forming galaxies, which can be obtained from their ratios of auroral lines [O II]7320,7330 to nebular lin…
