In this article, the detailed structure of the interaction of a strong stellar wind with the interstellar medium is presented, including the effects of thermal conduction between the hot interior and the cold shell of swept-up interstellar matter.Abstract:
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

Multi-frequency polarimetry of the Galactic radio background around 350 MHz. II. A region in Horologium around l = 137degr , b = 7degr
TL;DR: The Westerbork Synthesis Radio Telescope (WSRT) was used to take multi-frequency polarimetric images of the diffuse radio synchrotron background in a similar to 5degrees x 7degrees region centered on (l,b) = (161degrees,16degrees) in the constellation of Auriga as mentioned in this paper.

Radiative cooling of swept-up gas in AGN-driven galactic winds and its implications for molecular outflows
TL;DR: In this article, an analytic model was developed to follow cooling in the shocked ISM layer of an AGN wind, where the swept up gas mostly cools within 1 Myr.
