On the maximum value of the cosmic abundance of oxygen and the oxygen yield
L. S. Pilyugin, T. X. Thuan, J. M. Vilchez
We search for the maximum oxygen abundance in spiral galaxies. Because this maximum value is expected to occur in the centers of the most luminous galaxies, we have constructed the…
On the electron temperature determination in high-metallicity HII regions
L. S. Pilyugin
The problem of determination of the electron temperature t_2 in the OII zone of high-metallicity HII region was examined. It was shown that the ratio of nebular to auroral nitrogen…
On the origin of the luminosity - metallicity relation for late-type galaxies: Spirals to irregulars transition
L. S. Pilyugin, F. Ferrini
We consider the roles of two widely invoked mechanisms for the metallicity-luminosity correlation among late-type galaxies: higher astration level and decreasing efficiency of heav…
On the origin of nitrogen in low-metallicity galaxies: Blue compact galaxies versus damped Lya absorbers
L. S. Pilyugin
A remarkably small scatter in the N/O ratios for the HII regions in low-metallicity blue compact galaxies (BCG) has been found recently. It lead to the conclusion that N and O are…
