The big problems in star formation: the star formation rate, stellar clustering, and the initial mass function

MR Krumholz - Physics Reports, 2014 - Elsevier
Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

The role of magnetic fields in setting the star formation rate and the initial mass function

MR Krumholz, C Federrath - Frontiers in Astronomy and Space …, 2019 - frontiersin.org
Star-forming gas clouds are strongly magnetized, and their ionization fractions are high
enough to place them close to the regime of ideal magnetohydrodyamics on all but the …

The sonic scale of interstellar turbulence

C Federrath, RS Klessen, L Iapichino, JR Beattie - Nature Astronomy, 2021 - nature.com
Understanding the physics of turbulence is crucial for many applications, including weather,
industry and astrophysics. In the interstellar medium,, supersonic turbulence plays a crucial …

Inefficient star formation through turbulence, magnetic fields and feedback

C Federrath - Monthly Notices of the Royal Astronomical Society, 2015 - academic.oup.com
Star formation is inefficient. Only a few per cent of the available gas in molecular clouds
forms stars, leading to the observed low star formation rate (SFR). The same holds when …

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
timescale of the mass flows that create them. Based on extensive numerical simulations, we …

The link between turbulence, magnetic fields, filaments, and star formation in the central molecular zone cloud G0. 253+ 0.016

C Federrath, JM Rathborne, SN Longmore… - The Astrophysical …, 2016 - iopscience.iop.org
Star formation is primarily controlled by the interplay between gravity, turbulence, and
magnetic fields. However, the turbulence and magnetic fields in molecular clouds near the …

On the universality of interstellar filaments: theory meets simulations and observations

C Federrath - Monthly Notices of the Royal Astronomical Society, 2016 - academic.oup.com
Filaments are ubiquitous in the Universe. Recent observations have revealed that stars and
star clusters form preferentially along dense filaments. Understanding the formation and …

The ALMA Survey of 70 μm Dark High-mass Clumps in Early Stages (ASHES). VIII. Dynamics of Embedded Dense Cores

S Li, P Sanhueza, Q Zhang, G Guido… - The Astrophysical …, 2023 - iopscience.iop.org
We present dynamical properties of 294 cores embedded in twelve IRDCs observed as part
of the ASHES Survey. Protostellar cores have higher gas masses, surface densities, column …

Supernova driving. I. The origin of molecular cloud turbulence

P Padoan, L Pan, T Haugbølle… - The Astrophysical …, 2016 - iopscience.iop.org
Turbulence is ubiquitous in molecular clouds (MCs), but its origin is still unclear because
MCs are usually assumed to live longer than the turbulence dissipation time. Interstellar …

Magnetic field amplification in turbulent astrophysical plasmas

C Federrath - Journal of Plasma Physics, 2016 - cambridge.org
Magnetic fields play an important role in astrophysical accretion discs and in the interstellar
and intergalactic medium. They drive jets, suppress fragmentation in star-forming clouds and …
