Star Formation Regulation and Self-Pollution by Stellar Wind Feedback
Lachlan Lancaster, Eve C. Ostriker, Jeong-Gyu Kim +1
Stellar winds contain enough energy to easily disrupt the parent cloud surrounding a nascent star cluster, and for this reason have been considered candidates for regulating star f…
A Search for Wandering Black Holes in the Milky Way with Gaia and DECaLS
Jenny E. Greene, Lachlan Lancaster, Yuan-Sen Ting +6
We present a search for "hyper-compact" star clusters in the Milky Way using a combination of Gaia and the Dark Energy Camera Legacy Survey (DECaLS). Such putative clusters, with s…
Efficiently Cooled Stellar Wind Bubbles in Turbulent Clouds II. Validation of Theory with Hydrodynamic Simulations
Lachlan Lancaster, Eve C. Ostriker, Jeong-Gyu Kim +1
In a companion paper, we develop a theory for the evolution of stellar wind driven bubbles in dense, turbulent clouds. This theory proposes that turbulent mixing at a fractal bubbl…
Efficiently Cooled Stellar Wind Bubbles in Turbulent Clouds I. Fractal Theory and Application to Star-Forming Clouds
Lachlan Lancaster, Eve C. Ostriker, Jeong-Gyu Kim +1
Winds from massive stars have velocities of 1000 km/s or more, and produce hot, high pressure gas when they shock. We develop a theory for the evolution of bubbles driven by the co…
