The Sculptor Dwarf Irregular Galaxy (SDIG) —also known as ESO 349-G31 or PGC 621— is an irregular galaxy in the Sculptor group of galaxies. It is located at a distance of about 10 million light-years away from Earth, and was first detected from Earth in 1976. This article is about a celestial body. ...

The Projects (491 words)
Dwarf galaxies are expected to exist everywhere in the universe in large numbers, but at greater distances they are very hard to detect.
While the imaging of nearby dwarfs is continued with the long-term goal to reach completeness for LF studies, we are using the presently available photometric data to study the systematic dependence of the structural properties of dwarf galaxies (such as surface brightness, characteristic radii, and colors) on the environment.
Since dwarf galaxies are low-mass and low-density stellar systems, they are the most vulnerable type of galaxies with respect to evolutionary processes, such as tidal and ram pressure stripping, "harassment", induced star formation, etc. Significant environmental effect are expected to appear, which might provide important constraints on evolutionary scenarios.
* Dwarf - (Astronomy): Definition (2110 words)
Dwarf novae (DN) are a class of and that have multiple observed eruptions ranging in brightness from 2 to 5 magnitudes.
White Dwarfs are the remnants of stars that were massive enough to stay alive using nuclear fusion in their cores, but not massive enough to blow apart in a Type IIa supernova.
This is a barred spiral galaxy with DDO luminosity class I where bright supergiant well-formed spirals are type I and low surface brightness dwarfs with little or no spiral structure are of type V and types II, III and IV are intermediates of these.
