information on the population of star-forming dwarf galaxies. Large numbers of very nearby star-forming dwarfs have been studied (e.g., Terlevich et al. , Hunter, Hawley, & Gal-lagher , van Zee , ), but complete star formation inventories, extending across the full range of galaxy types andmasses, are lacking.   Star forming dwarf galaxies (SFDGs) have a high gas content and low metallicities, reminiscent of the basic entities in hierarchical galaxy formation scenarios. In the young universe they probably also played a major role in the cosmic by: es: dwarf, galaxies: evolution, galaxies: ISM, galaxies: interactions 1. Introduction More than 70% of all galaxies in the Local Volume are star-forming dwarf galaxies (SFDGs; Karachentsev et al. ), i.e. low-mass systems rich in atomic gas (Hi) and a low metal and dust content.

The authors have obtained CCD observations of ≡50 blue compact dwarf galaxies (BCD's) from the list of Thuan and Martin. They use the CCD material to propose a classification scheme for BCD's based on the regularity of the isophotal shapes of both the high-surface-brightness star-forming regions and the low-surface-brightness outer regions. • More than one family of objects:! – Gas-poor, passive (dE and dSph)! – Gas-rich, star forming! • Why are dwarf galaxies important?! – Majority of galaxies are dwarfs!! – Dwarf galaxies may be remnants of galaxy formation process: relatively simple systems, not merger products! – Dwarf galaxies . Recently discovered compact interstellar clouds in a nearby dwarf irregular galaxy help explain how dense star clusters are able to form in such a tenuous environment.   Galaxies can be found by themselves, in small groups and in large clusters. It is very rare to find stars in the space in between galaxies. Galaxies sometimes collide with each other, with interesting results. These collisions can trigger bursts of star-formation in addition to changing the shapes of the galaxies that collide.

Its membership of.   These clusters of stars, with less than , solar masses, had fever stars than found within the other previously discovered dwarf galaxies. Further study showed why the objects .
