Non-ideal MHD and protostellar feedback effects on disc formation and evolution in numerical simulations of star cluster formation
Nina Filippova, Stella S. R. Offner, Michael Y. Grudic +1
While recent surveys have resolved hundreds of nearby protostellar discs, numerical simulations assuming ideal magnetohydrodynamics (MHD) have historically struggled to achieve dis…
Residual energy in weakly compressible turbulence with a mean guide field
R. Skalidis, A. Tritsis, J. R. Beattie +1
The energy distribution is a fundamental property of magnetohydrodynamic (MHD) turbulence. In strongly magnetized turbulence energy imbalances arise and are quantified by the resid…
Dust Battery: A Novel Mechanism for Seed Magnetic Field Generation in the Early Universe
Nadine H. Soliman, Philip F. Hopkins, Jonathan Squire
We propose a novel dust battery mechanism for generating seed magnetic fields in the early universe, in which charged dust grains are radiatively accelerated, inducing strong elect…
Rapid, strongly magnetized accretion in the zero-net-vertical-flux shearing box
Jonathan Squire, Eliot Quataert, Philip F. Hopkins
We show that there exist two qualitatively distinct turbulent states of the zero-net-vertical-flux shearing box. The first, which has been studied in detail previously, is characte…
Are Stars Really Ingesting their Planets? Examining an Alternative Explanation
Nadine H. Soliman, Philip F. Hopkins
Numerous stars exhibit surprisingly large variations in their refractory element abundances, often interpreted as signatures of planetary ingestion events. In this study, we propos…
The First Evidence of a Host Star Metallicity Cut-off In The Formation of Super-Earth Planets
Kiersten M. Boley, Jessie L. Christiansen, Jon Zink +7
Planet formation is expected to be severely limited in disks of low metallicity, owing to both the small solid mass reservoir and the low opacity accelerating the disk gas dissipat…
