Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters
of stars, they exhibit signs of some chemical evolution. At least for this reason, they are …

The development of different analytical and approximate numerical methods for calculations
of shock-wave propagation in the inhomogeneous interstellar medium is reviewed. The …

We present a smoothed particle hydrodynamics parameter study of the dynamical effect of
photoionization from O-type stars on star-forming clouds of a range of masses and sizes …

Context. This study deals with infrared bubbles, the H ii regions they enclose, and triggered
massive-star formation on their borders. Aims. We attempt to determine the nature of the …

From the available observational and theoretical evidence it is argued that the mass of
molecular gas in the Galaxy has been considerably overestimated and that the ages of the …

We use 3D hydrodynamical models to investigate the effects of massive star feedback from
winds and supernovae on inhomogeneous molecular material left over from the formation of …

Feedback from massive stars is believed to be a key element in the evolution of molecular
clouds. We use high-resolution 3D smoothed particle hydrodynamics simulations to explore …

Cloud environment is thought to play a critical role in determining the mechanism of
formation of massive stars. In this contribution we review the physical characteristics of the …

We present two-dimensional hydrodynamical and magnetohydrodynamical simulations of
the evolution of planetary nebulae formed through the interaction of two succeeding, time …

We describe a photon-conserving radiative transfer algorithm, using a spatially-adaptive ray-
tracing scheme, and its parallel implementation into the adaptive mesh refinement …
