Star formation laws and efficiencies across 80 nearby galaxies

J Sun, AK Leroy, EC Ostriker, S Meidt… - The Astrophysical …, 2023 - iopscience.iop.org
We measure empirical relationships between the local star formation rate (SFR) and
properties of the star-forming molecular gas on 1.5 kpc scales across 80 nearby galaxies …

Pressure-regulated, Feedback-modulated Star Formation in Disk Galaxies

EC Ostriker, CG Kim - The Astrophysical Journal, 2022 - iopscience.iop.org
The star formation rate (SFR) in galactic disks depends on both the quantity of the available
interstellar medium (ISM) gas and its physical state. Conversely, the ISM's physical state …

Understanding the physics of turbulence is crucial for many applications, including weather,
industry and astrophysics. In the interstellar medium,, supersonic turbulence plays a crucial …

Star formation efficiency and dispersal of giant molecular clouds with UV radiation feedback: dependence on gravitational boundedness and magnetic fields

JG Kim, EC Ostriker, N Filippova - The Astrophysical Journal, 2021 - iopscience.iop.org
Molecular clouds are supported by turbulence and magnetic fields, but quantifying their
influence on cloud life cycle and star formation efficiency (SFE) remains an open question …

The origin of massive stars: The inertial-inflow model

P Padoan, L Pan, M Juvela, T Haugbølle… - The Astrophysical …, 2020 - iopscience.iop.org
We address the problem of the origin of massive stars, namely the origin, path, and
