The Open University ’ s repository of research publications and other research outputs Star formation triggered by the Galactic HII region RCW 120 : first results from the Herschel Space
Context. By means of different physical mechanisms, the expansion of H ii regions can promote the formation of new stars of all masses. RCW 120 is a nearby Galactic H ii region where triggered star formation occurs. This region is well-studied – there being a wealth of existing data – and is nearby. However, it is surrounded by dense regions for which far infrared data is essential to obtain an...
متن کاملThe physical properties of the dust in the RCW 120 H II region as seen by Herschel
Context. RCW 120 is a well-studied, nearby Galactic H ii region with ongoing star formation in its surroundings. Previous work has shown that it displays a bubble morphology at mid-infrared wavelengths, and has a massive layer of collected neutral material seen at sub-mm wavelengths. Given the well-defined photo-dissociation region (PDR) boundary and collected layer, it is an excellent laborato...
متن کاملUnderstanding our Origins : Star Formation in H ii Region Environments
Recent analysis of the decay products of short-lived radiounclides (SLRs) in meteorites, in particular the confirmation of the presence of live Fe in the early Solar System, provides unambiguous evidence that the Sun and Solar System formed near a massive star. We consider the question of the formation of low-mass stars in the environments of massive stars, presenting a scenario for the evoluti...
