Massive clumps within the swept-up shells of bubbles, like that surrounding the galactic H II region RCW 120, have been interpreted in terms of the collect and collapse (C&C) mechanism for triggered star formation. The cold, dusty clumps surrounding RCW 120 are arranged in an almost spherical shell and harbour many young stellar objects. By performing high-resolution, three-dimensional smoothed particle hydrodynamics simulations of H II regions expanding into fractal molecular clouds, we…

Stellar feedback and triggered star formation in the prototypical bubble RCW 120

Observations of RCW 120 show that triggered star formation can occur on much shorter time scales than previously thought. Radiative and mechanical feedback of massive stars regulates star formation

Cloud-cloud collision as a trigger of the high-mass star formation; a molecular line study in RCW120

RCW 120 is a Galactic H ii region that has a beautiful ring shape that is bright in the infrared. Our new CO J = 1–0 and J = 3–2 observations performed with the NANTEN2, Mopra, and ASTE telescopes

APEX CO observations towards the photodissociation region of RCW 120

The edges of ionized (HII) regions are important sites for the formation of (high-mass) stars. Indeed, at least 30% of the galactic high mass star formation is observed there. The radiative and

RCW 120: a possible case of hit and run, elucidated by multitemperature dust mapping

We present resolution-enhanced images of warm dust at multiple temperatures and opacity index values in the star-forming bubble/H ii region, RCW 120. The image set, representing a four-dimensional

Colliding interstellar bubbles in the direction of l = 54

Context. Interstellar bubbles are structures in the interstellar medium with diameters of a few to tens of parsecs. Their progenitors are stellar winds, intense radiation of massive stars, or

Triggered Star Formation inside the Shell of a Wolf–Rayet Bubble as the Origin of the Solar System

It is estimated that 1%-16% of all Sun-like stars could have formed in such a setting of triggered star formation in the shell of a W-R bubble, and this model is a viable model that can explain the initial abundances of 26Al and 60Fe.

NH3 observations of the S235 star-forming region: Dense gas in inter-core bridges

Star formation is thought to be driven by two groups of mechanisms; spontaneous collapse and triggered collapse. Triggered star formation mechanisms further diverge into cloud–cloud collision


We present radiation hydrodynamic simulations of collapsing protostellar cores with initial masses of 30, 100, and 200 M⊙. We follow their gravitational collapse and the formation of a massive

Molecular envelope around the HII region RCW 120

The H ii region RCW 120 is a well-known object, which is often considered as a target to verify theoretical models of gas and dust dynamics in the interstellar medium. However, the exact geometry

Ionization-induced star formation - I. The collect-and-collapse model

We conduct smoothed particle hydrodynamics simulations of the ‘collect-and-collapse’ scenario for star formation triggered by an expanding H ii region. We simulate the evolution of a spherical

Clumps and triggered star formation in ionized molecular clouds

Infrared shells and bubbles are ubiquitous in the Galaxy and can generally be associated with Hii regions formed around young, massive stars. In this paper, we use high-resolution 3D SPH simulations

The Preferential Formation of High-Mass Stars in Shocked Interstellar Gas Layers

Gravitationally unstable, shocked layers of interstellar gas are produced by cloud-cloud collisions and by expanding nebulae around massive stars. We show that the resulting fragments are likely to
