The detailed structure of the interaction of a strong stellar wind with the interstellar medium is presented. First, an adiabatic similarity solution is given which is applicable at early times. Second, a similarity solution is derived which includes the effects of thermal conduction between the hot (about 1 million K) interior and the cold shell of swept-up interstellar matter. This solution is then modified to include the effects of radiative energy losses. The evolution of an interstellar bubble is calculated, including the radiative losses. The quantitative results for the outer-shell radius and velocity and the column density of highly ionized species such as O VI are within a factor 2 of the approximate results of Castor, McCray, and Weaver (1975). The effect of stellar motion on the structure of a bubble, the hydrodynamic stability of the outer shell, and the observable properties of the hot region and the outer shell are discussed.read more

Hydrodynamics of Cometary Compact H II Regions
TL;DR: In this paper, the authors present numerical radiation-hydrodynamic simulations of cometary H II regions for a number of champagne flow and bow shock models, and show that these models combine density gradients and stellar winds are able to account for both the morphology and general radial velocity behavior of several observed cometary h II regions.

A Chandra ACIS Study of 30 Doradus. II. X-Ray Point Sources in the Massive Star Cluster R136 and Beyond
TL;DR: In this article, the authors studied the X-ray point-source population of the 30?Doradus (30 Dor) star-forming complex in the Large Magellanic Cloud using high-resolution images and spatially resolved spectra obtained with the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra X-Ray Observatory.
