Dwarfgalaxies 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 dwarfgalaxies (such as surface brightness, characteristic radii, and colors) on the environment.
Since dwarfgalaxies 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 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.
