Assessing Stellar Wind Feedback in 30 Doradus using Deep Chandra and JWST Observations

Stellar winds are an important feedback mechanism in massive star clusters, depositing significant energy to the surrounding medium. X-ray studies of HII regions have demonstrated that the kinetic energy of winds may be lost through a variety of mechanisms, such as leakage, radiative cooling, and dust heating. In this poster, we present an analysis of the deep 2-Ms Chandra X-ray observation of the giant HII region 30 Doradus, with comparison to the new JWST mosaics, revealing a complex structure and the relationship between the stars and multi-phase gas. We assess the conditions of the hot gas to explore the kinetic energy loss channels, setting important constraints on the efficacy of wind feedback.
