Star Formation Mitosis: The Effects of Particle Splitting on the Star Formation Outcome
Shivan Khullar, Michael Y. Grudić, Christopher D. Matzner +3
Particle splitting can increase the dynamic range in Lagrangian astrophysical simulations by several orders of magnitude. However, such methods can introduce numerical noise that m…
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…
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…
Thermodynamics of Giant Molecular Clouds: The Effects of Dust Grain Size
Nadine H. Soliman, Philip F. Hopkins, Michael Y. Grudić
The dust grain size distribution (GSD) likely varies significantly across star-forming environments in the Universe, but its impact on star formation remains unclear. This ambiguit…
Playing with FIRE: A Galactic Feedback-Halting Experiment Challenges Star Formation Rate Theories
Shivan Khullar, Christopher D. Matzner, Norman Murray +4
Stellar feedback influences the star formation rate (SFR) and the interstellar medium of galaxies in ways that are difficult to quantify numerically, because feedback is an essenti…
Dust-Evacuated Zones Near Massive Stars: Consequences of Dust Dynamics on Star-forming Regions
Nadine H. Soliman, Philip F. Hopkins, Michael Y. Grudić
Stars form within dense cores composed of both gas and dust within molecular clouds. However, despite the crucial role that dust plays in the star formation process, its dynamics i…
The effects of metallicity and cooling physics on fragmentation: implications on direct-collapse black hole formation
C. Corbett Moran, M. Y. Grudić, P. F. Hopkins
A promising supermassive black hole seed formation channel is that of direct collapse from primordial gas clouds. We perform a suite of 3D hydrodynamics simulations of an isolated…
