The N/O abundance ratio in the lowest-metallicity blue compact dwarf galaxies
Y. Izotov, F. Chaffee, C. Foltz +6
The results of the N/O abundance determination in a sample of low-metallicity blue compact dwarf (BCD) galaxies based on new spectroscopic observations with large telescopes (Keck,…
A spectroscopic study of component C and the extended emission around I Zw 18
Y. I. Izotov, F. H. Chaffee, C. B. Foltz +5
Long-slit Keck II, 4m Kitt Peak, and 4.5m MMT spectrophotometric data are used to investigate the stellar population and the evolutionary status of I Zw 18C, the faint C component…
The evolutionary status of the low-metallicity blue compact dwarf galaxy SBS 0940+544
N. G. Guseva, Y. I. Izotov, P. Papaderos +6
We present the results of spectrophotometry and V,R,I, Halpha CCD photometry of the blue compact dwarf (BCD) galaxy SBS 0940+544. Broad-band images taken with the 2.1m KPNO and 1.2…
