Single-hemisphere dynamos in M-dwarf stars
Benjamin P. Brown, Jeffrey S. Oishi, Geoffrey M. Vasil +2
M-dwarf stars below a certain mass are convective from their cores to their photospheres. These fully convective objects are extremely numerous, very magnetically active, and the l…
Improved phase-field models of melting and dissolution in multi-component flows
Eric W. Hester, Louis-Alexandre Couston, Benjamin Favier +2
We develop and analyse the first second-order phase-field model to combine melting and dissolution in multi-component flows. This provides a simple and accurate way to simulate cha…
The Magnetorotational Instability Prefers Three Dimensions
Jeffrey S. Oishi, Geoffrey M. Vasil, Morgan Baxter +4
The magnetorotational instability (MRI) occurs when a weak magnetic field destabilises a rotating, electrically conducting fluid with inwardly increasing angular velocity. The MRI…
Linearly forced fluid flow on a rotating sphere
Rohit Supekar, Vili Heinonen, Keaton J. Burns +1
We investigate generalized Navier-Stokes (GNS) equations that couple nonlinear advection with a generic linear instability. This analytically tractable minimal model for fluid flow…
Low-frequency variability in massive stars: Core generation or surface phenomenon?
Daniel Lecoanet, Matteo Cantiello, Eliot Quataert +6
Bowman et al. (2019) reported low-frequency photometric variability in 164 O- and B-type stars observed with K2 and TESS. They interpret these motions as internal gravity waves, wh…
Dedalus: A Flexible Framework for Numerical Simulations with Spectral Methods
Keaton J. Burns, Geoffrey M. Vasil, Jeffrey S. Oishi +2
Numerical solutions of partial differential equations enable a broad range of scientific research. The Dedalus Project is a flexible, open-source, parallelized computational framew…
