Clumpy ultracompact HII regions -- III. Cometary morphologies around stationary stars
R. J. R. Williams, J. E. Dyson, M. P. Redman
Cometary ultracompact HII regions have been modelled as the interaction of the hypersonic wind from a moving star with the molecular cloud which surrounds the star. We here show th…

Clumpy ultracompact HII regions -- II. Cores, spheres and shells from subsonic flows
M. P. Redman, R. J. R. Williams, J. E. Dyson
We have modelled ultracompact HII regions (UCHIIR) in terms of steady subsonic ionized flows in a clumpy medium. Mass loss from neutral clumps allows the regions to be long-lived.…
