Reducing the complexity of chemical networks via interpretable autoencoders
T. Grassi, F. Nauman, J. P. Ramsey +3
In many astrophysical applications, the cost of solving a chemical network represented by a system of ordinary differential equations (ODEs) grows significantly with the size of th…
Transport properties of Keplerian flows in extended local domains with no imposed field
Farrukh Nauman, Martin E. Pessah
We compare transport statistics of elongated incompressible shearing boxes for different Reynolds and magnetic Prandtl numbers, and , and aspect ratios, . We find…
Exploring helical dynamos with machine learning
Farrukh Nauman, Joonas Nättilä
We use ensemble machine learning algorithms to study the evolution of magnetic fields in magnetohydrodynamic (MHD) turbulence that is helically forced. We perform direct numerical…
The effects of large scale magnetic fields around young protostars and their disks
Michael Kuffmeier, Farrukh Nauman
We study the evolution of magnetic fields in accretion flows around six different sink particles in a global star formation simulation. Using the adaptive mesh refinement capabilit…
Sustained turbulence and magnetic energy in non-rotating shear flows
Farrukh Nauman, Eric G. Blackman
From numerical simulations, we show that non-rotating magnetohydrodynamic shear flows are unstable to finite amplitude velocity perturbations and become turbulent, leading to the g…
Sustained Turbulence in Differentially Rotating Magnetized Fluids at Low Magnetic Prandtl Number
Farrukh Nauman, Martin E. Pessah
We show for the first time that sustained turbulence is possible at low magnetic Prandtl number for Keplerian flows with no mean magnetic flux. Our results indicate that increasing…
Shearing box simulations in the Rayleigh unstable regime
Farrukh Nauman, Eric G. Blackman
We study the stability properties of Rayleigh unstable flows both in the purely hydrodynamic and magnetohydrodynamic (MHD) regimes for two different values of the shear $q=2.1, 4.2…
Motivation and challenge to capture both large scale and local transport in next generation accretion theory
Eric G. Blackman, Farrukh Nauman
Accretion disc theory is less developed than stellar evolution theory although a similarly mature phenomenological picture is ultimately desired. While the interplay of theory and…
Sensitivity of the Magnetorotational Instability to the shear parameter in stratified simulations
Farrukh Nauman, Eric G. Blackman
The magnetorotational instability (MRI) is a shear instability and thus its sensitivity to the shear parameter is of interest to investigate. Motivated by ast…
On characterizing nonlocality and anisotropy for the magnetorotational instability
Farrukh Nauman, Eric G. Blackman
The extent to which angular momentum transport in accretion discs is primarily local or non-local and what determines this is an important avenue of study for understanding accreti…
Quantifying the Imprecision of Accretion Theory and Implications for Multi-Epoch Observations of Protoplanetary Discs
Eric G. Blackman, Farrukh Nauman, Richard G. Edgar
If accretion disc emission results from turbulent dissipation, then axisymmetric accretion theory must be used as a mean field theory: turbulent flows are at most axisymmetric only…
