1Circumstellar disk — A circumstellar disk is a torus, pancake or ring shaped accumulation of matter composed of gas, dust, planetesimals, asteroids or collision fragments in orbit around a star. Around the youngest stars, they are the reservoirs of material out of… …
2Cosmic dust — Space dust redirects here. For other uses, see Space dust (disambiguation). Porous chondrite interplanetary dust particle. Cosmic dust is a type of dust composed of particles in space which are a few molecules to 0.1 µm in size. Cosmic dust… …
3Molecular cloud — See also: Solar nebula Within a few million years the light from bright stars will have boiled away this molecular cloud of gas and dust. The cloud has broken off from the Carina Nebula. Newly formed stars are visible nearby, their images… …
4Comet dust — refers to cosmic dust that originates from a comet. Comet dust can provide clues to comets origin. Dust and comet origin Microscopic view of comet dust particle The models for the origin of comets are[1]: 1) the interstellar model, 2) the solar… …
5Circular polarization — The electric field vectors of a traveling circularly polarized electromagnetic wave. In electrodynamics, circular polarization[1] of an electromagnetic wave is a polarization in which the electric field of the passing wave does not change… …
6Circular polarization of starlight — The circular polarization of starlight has been observed to be a function of the linear polarization of starlight.Starlight becomes partially linearly polarized by scattering from elongated interstellar dust grains whose long axes tend to be… …
7Color–color diagram — In astronomy, color–color diagrams are a means of comparing the apparent magnitudes of stars at different wavelengths. Astronomers typically observe at narrow bands around certain wavelengths, and objects observed will have different brightnesses …
