Spectrophotometry of H II regions in the spiral galaxy M101

K E Sedwick 1, L H Aller 1
PMCID: PMC319268  PMID: 16592999

Abstract

Spectral line intensity data are presented for ionized hydrogen regions in the giant spiral galaxy M101. The influence of interstellar extinction is assessed and electron temperatures of the gas clouds are derived.

Keywords: gaseous nebulae, chemical composition gradients
