blue compact dwarf galaxy | карликовая голубая компактная галактика (A blue compact dwarf galaxy (BCD) is the lowest luminosity type of starburst galaxy. It is a small galaxy, about one-tenth the size of a typical large spiral such as the Milky Way, that appears blue by virtue of containing large clusters of hot, massive stars, which ionize the surrounding interstellar gas with their intense ultraviolet radiation. These massive blue stars are very young by stellar standards – under ten million years or so old. They were created in a huge starburst, a violent episode of star formation that in some cases engulfs an entire galaxy. daviddarling.info 'More) |

dwarf elliptical galaxy | карликовая эллиптическая галактика (Dwarf elliptical galaxies (dEs) are elliptical galaxies that are smaller than ordinary elliptical galaxies. They are quite common in galaxy groups and clusters, and are usually companions to other galaxies. wikipedia.org 'More) |
dwarf irregular galaxy | карликовая неправильная галактика (A dI-galaxy (or dIrr) is a dwarf irregular galaxy. This type of galaxy is now thought to be important to understand the overall evolution of galaxies, as they tend to have a low level of metallicity and relatively high levels of gas, and are thought to be similar to the earliest galaxies that populated the Universe. They may represent a local (and therefore more recent) version of the faint blue galaxies known to exist in deep field galaxy surveys. wikipedia.org 'More) |
dwarf spheroidal galaxy | карликовая сфероидальная галактика (A dwarf spheroidal galaxy (dSph) is a term in astronomy applied to small, low-luminosity galaxies with very little dust and an older stellar population. They are found in the Local Group as companions to the Milky Way and as systems that are companions to the Andromeda Galaxy (M31). While similar to dwarf elliptical galaxies in appearance and properties such as little to no gas or dust or recent star formation, they are approximately spheroidal in shape and generally have lower luminosity. wikipedia.org 'More) |
dwarf spiral galaxy | карликовая спиральная галактика (разновидность спиральных галактик, отличающаяся небольшими размерами (меньше 5 кпк), слабой светимостью и низкой поверхностной яркостью. Карликовые спиральные галактики относят к подклассу карликовых галактик. Карликовые спиральные галактики, особенно аналоги спиральных галактик типов Sa-Sc, чрезвычайно редки, в то время как карликовые эллиптические или карликовые неправильные галактики широко распространены во Вселенной.
