On the hydrodynamics of the matter reinserted within superstellar clusters
Guillermo Tenorio-Tagle, Richard Wunsch, Sergiy Silich +1
We present semi-analytical and numerical models, accounting for the impact of radiative cooling on the hydrodynamics of the matter reinserted as strong stellar winds and supernovae…
The fragmentation of expanding shells I: Limitations of the thin--shell approximation
James E. Dale, Richard Wunsch, Anthony Whitworth +1
We investigate the gravitational fragmentation of expanding shells in the context of the linear thin--shell analysis. We make use of two very different numerical schemes; the FLASH…
The fragmentation of expanding shells II: Thickness matters
Richard Wunsch, James E. Dale, Jan Palous +1
We study analytically the development of gravitational instability in an expanding shell having finite thickness. We consider three models for the radial density profile of the she…
GS242-03+37: a lucky survivor in the galactic gravitational field
Sona Ehlerova, Jan Palous
HI shells and supershells, found in discs of many galaxies including our own, are formed by the activity of young and massive stars (supernova explosions and stellar winds), but th…
Correlation of HI shells and CO clumps in the outer Milky Way
Sona Ehlerova, Jan Palous
HI shells, which may be formed by the activity of young and massive stars, or connected to energy released by interactions of high-velocity clouds with the galactic disk, may be pa…
On the fate of the matter reinserted within young nuclear stellar clusters
Filiberto Hueyotl-Zahuantitla, Jan Palous, Richard Wunsch +2
This paper presents a hydrodynamical model describing the evolution of the gas reinserted by stars within a rotating young nuclear star cluster (NSC). We explicitly consider the im…
