Cosmic Ray Feedback in Galactic Disks: Star Formation, Cosmic Ray Transport, and Multiphase Outflows in TIGRESS++ Simulations
Chang-Goo Kim, Lucia Armillotta, Eve C. Ostriker +5
We present new simulations of local star-forming disks that self-consistently evolve cosmic rays (CRs) and multiphase gas using TIGRESS++. To isolate the role of CRs, we conduct pa…
Prestellar Cores in Turbulent Clouds: Observational Perspectives on Structure, Kinematics, and Lifetime
Sanghyuk Moon, Eve C. Ostriker
We analyze an ensemble of simulated prestellar cores to facilitate interpretation of structure, kinematics, and lifetime of observed cores. While our theory predicts a "characteris…
Prestellar Cores in Turbulent Clouds: Properties of Critical Cores
Sanghyuk Moon, Eve C. Ostriker
A fraction of the dense cores within a turbulent molecular cloud will eventually collapse to form stars. Identifying the physical criteria for instability and analyzing critical co…
Prestellar Cores in Turbulent Clouds: Numerical Modeling and Evolution to Collapse
Sanghyuk Moon, Eve C. Ostriker
A fundamental issue in star formation is understanding the precise mechanisms leading to the formation of prestellar cores, and their subsequent gravitationally unstable evolution.…
Theory of Turbulent Equilibrium Spheres with Power-Law Linewidth-Size Relation
Sanghyuk Moon, Eve C. Ostriker
Dense cores inherit turbulent motions from the interstellar medium in which they form. As a tool for comparison to both simulations and observations, it is valuable to construct th…
