3D Morphology of Open Clusters in the Solar Neighborhood

A spiral galaxy like the Milky Way contains stars, stellar remnants, and a diffuse interstellar medium (ISM) of gas and dust. The interstellar medium consists of 10 to 10 particles per cm and is typically composed of roughly 70% hydrogen by mass, with most of the remaining gas consisting of helium. This medium has been chemically enriched by trace amounts of heavier elements that were prod… Webmodes: ‘clustered’ and ‘ eld’ or ‘distributed’ star formation (Lada & Lada2003).
