Keywords: HII regions – Star formation rate – Extinction. 1 Introduction A simple measure of the star formation rate (SFR) in a galaxy is the Hα luminosity emitted by the ionizad gas in the galaxy.

WebBecause this jump is fairly common, HII regions give off a lot of red light. In a tri-color image using red, green and blue filters, HII regions appear pink. (BUT: SDSS tri-color images use the green, red, and near infrared filters to make color images - confusing, no? In SDSS images, HII regions appear light blue instead of pink.) WebH II region, also called diffuse nebula or emission nebula, interstellar matter consisting of ionized hydrogen atoms. The energy that is responsible for ionizing and heating the hydrogen in an emission nebula comes from a central star that has a surface temperature in excess of 20,000 K.
