| Abstract: | Stars form from the interstellar medium. Once formed, they modify the interstellar medium by ionizing it, sending shock waves through it, and forming bubbles of hot, low density gas. This "structuring" of the interstellar medium probably modifies, in major ways, the physical processes of star formation. As a modest contribution to this study, I describe our research program to study the plasma shells or "bubbles" formed around hot, luminous stars with powerful winds. Our particular interest is the form of the magnetic field in the dense ionized shells around these stellar bubbles. I will describe our results to date with observations of these shells and bubbles with the Very Large Array radio telescope. | |
