On the diversity and statistical properties of protostellar discs

MR Bate - Monthly Notices of the Royal Astronomical Society, 2018 - academic.oup.com
We present results from the first population synthesis study of protostellar discs. We analyse
the evolution and properties of a large sample of protostellar discs formed in a radiation …

Global simulations of the inner regions of protoplanetary disks with comprehensive disk microphysics

XN Bai - The Astrophysical Journal, 2017 - iopscience.iop.org
The gas dynamics of weakly ionized protoplanetary disks (PPDs) are largely governed by
the coupling between gas and magnetic fields, described by three non-ideal …

Magneto-thermal disk winds from protoplanetary disks

XN Bai, J Ye, J Goodman, F Yuan - The Astrophysical Journal, 2016 - iopscience.iop.org
The global evolution and dispersal of protoplanetary disks (PPDs) are governed by disk
angular-momentum transport and mass-loss processes. Recent numerical studies suggest …

Radiation magnetohydrodynamic simulations of protostellar collapse: nonideal magnetohydrodynamic effects and early formation of circumstellar disks

K Tomida, S Okuzumi, MN Machida - The Astrophysical Journal, 2015 - iopscience.iop.org
The transport of angular momentum by magnetic fields is a crucial physical process in the
formation and evolution of stars and disks. Because the ionization degree in star-forming …

Formation of a Keplerian disk in the infalling envelope around L1527 IRS: transformation from infalling motions to Kepler motions

Dust coagulation during the early stages of star formation: molecular cloud collapse and first hydrostatic core evolution

MR Bate - Monthly Notices of the Royal Astronomical Society, 2022 - academic.oup.com
Planet formation in protoplanetary discs requires dust grains to coagulate from the sub-
micron sizes that are found in the interstellar medium into much larger objects. For the first …

Can non-ideal magnetohydrodynamics solve the magnetic braking catastrophe?

J Wurster, DJ Price, MR Bate - Monthly Notices of the Royal …, 2016 - academic.oup.com
We investigate whether or not the low ionization fractions in molecular cloud cores can solve
the 'magnetic braking catastrophe', where magnetic fields prevent the formation of …
