Description
Based on the Sérsic parameters, obtained by fitting pixel to pixel their deep optical galaxy images, the structural properties of the underlying stellar host of a sample of 20 star-forming dwarf galaxies have been analyzed. Our 2D technique has been improved to derive reliable Sérsic models, such as the proper isolation of the starburst emission, by using accurate masks in several steps. How the host of a blue compact galaxy (BCG) relates with different types of galaxies has been investigated by using diagrams built upon the Sérsic parameters. H I gas masses and line-widths taken from the literature have been used to compare the B-band luminosity, stellar, and baryonic (H I gas+stars) Tully-Fisher relations for BCG hosts with those for late-type disk galaxies.

Starsbursts play a key role in the cosmic evolution of galaxies, and thus in the star formation (SF) history of the universe, the production of metals, and the feedback coupling galaxies with the cosmic web. Extreme SF conditions prevail early on during the formation of the first stars and galaxies, therefore, the starburst phenomenon constitutes a
