Abstract
Observations with the 6-m telescope of the Special Astrophysical Observatory obtained with the MPFS panoramic spectrograph and a slit spectrograph with the SCORPIO focal reducer are used to analyze the emission spectrum of the ionized gas in a star-forming region in the BCD galaxy VII Zw 403. We present images of the galaxy’s central region in Hα, Hβ, [SII], and [OIII], together with maps of the relative [OIII]/Hβ and [SII]/Hα intensities. We have determined the parameters of the gas in bright ionized supershells, and estimated the relative abundances of oxygen, nitrogen, and sulfur; a low relative N/O abundance was detected.
