Název v původním jazyce

Gould’s Belt: Local Large Scale Structure in the Milky Way

Popis výsledku v původním jazyce

Gould’s Belt is a flat local system composed of young massive stars of spectral types O or early-type B (OB stars), molecular clouds, and neutral hydrogen within 500 pc of the Sun. Gould’s Belt expands and revolves around a local nearby center in the direction of the Cassiopeia–Taurus OB association. We discuss possible models of its origin: free expansion from a point or from a ring, expansion of a shell into the smooth or porous interstellar medium, and a collision of a high-velocity cloud with the plane of the MilkyWay. Some of these anomalous motions may have originated in phenomena generated by supernova explosions. The models match the elliptical shape of Gould’s Belt. Currently, no convincing model exists. Similar structures are identified in the distribution of neutral hydrogen atoms and molecules in our own and other nearby galaxies.
