Title: Magnetic fields and Star Formation around HII regions: The S235 complex
Authors: R. Devaraj et al.
First Author’s Institution: Dublin Institute for Advanced Studies, Ireland
Status: Published in ApJ
Massive young stars heat the interstellar material around them, creating HII regions, or areas full of ionized hydrogen. As the stars push stellar wind and ultraviolet radiation outward, their HII regions expand, and a balloon of interstellar material begins to collect around the central star. Surrounding gas and dust is swept up by the balloon, and the magnetic field changes.
Astronomers know that magnetic fields play an important role in star formation. And we also know that expanding HII regions can trigger star formation. But how the two fit together in the overall process of creating new stars remains mysterious. Today’s paper examines S235, a star-forming complex that is home to HII regions and young stellar objects, in order to explore how ...
