The bound origin of low-mass stellar binaries
A. Generozov, S. S. R. Offner, K. M. Kratter +3
Most main sequence stars, unlike our Sun, belong to multiple systems with two or more stars. How and when these multiples come together and become bound is uncertain, since the ear…
Further correction to the STARFORGE methods paper: Planck-mean dust opacities
Michael Y. Grudić, Dávid Guszejnov, Philip F. Hopkins +2
The model for the Planck-mean dust opacity given in Appendix C of the STARFORGE simulations methods paper does not extrapolate well to low radiation temperature $T_{\rm rad…
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…
FORGE'd in FIRE III: The IMF in Quasar Accretion Disks from STARFORGE
Philip F. Hopkins, Michael Y. Grudic, Kyle Kremer +3
Recently, we demonstrated self-consistent formation of strongly-magnetized quasar accretion disks (QADs) from cosmological radiation-magnetohydrodynamic-thermochemical galaxy-star…
Stellar Populations in STARFORGE: The Origin and Evolution of Star Clusters and Associations
Juan P. Farias, Stella S. R. Offner, Michael Y. Grudić +2
Most stars form in highly clustered environments within molecular clouds, but eventually disperse into the distributed stellar field population. Exactly how the stellar distributio…
Predicting the Radiation Field of Molecular Clouds using Denoising Diffusion Probabilistic Models
Duo Xu, Stella Offner, Robert Gutermuth +3
Accurately quantifying the impact of radiation feedback in star formation is challenging. To address this complex problem, we employ deep learning techniques, denoising diffusion p…
FORGE'd in FIRE: Resolving the End of Star Formation and Structure of AGN Accretion Disks from Cosmological Initial Conditions
Philip F. Hopkins, Michael Y. Grudic, Kung-Yi Su +8
It has recently become possible to zoom-in from cosmological to sub-pc scales in galaxy simulations to follow accretion onto supermassive black holes (SMBHs). However, at some poin…
Does God play dice with star clusters?
Michael Y. Grudić, Stella S. R. Offner, Dávid Guszejnov +2
When a detailed model of a stellar population is unavailable, it is most common to assume that stellar masses are independently and identically distributed according to some distri…
Effects of the environment on the multiplicity properties of stars in the STARFORGE simulations
Dávid Guszejnov, Aman N. Raju, Stella S. R. Offner +4
Most observed stars are part of a multiple star system, but the formation of such systems and the role of environment and various physical processes is still poorly understood. We…
Effects of the environment and feedback physics on the initial mass function of stars in the STARFORGE simulations
Dávid Guszejnov, Michael Y. Grudić, Stella S. R. Offner +3
One of the key mysteries of star formation is the origin of the stellar initial mass function (IMF). The IMF is observed to be nearly universal in the Milky Way and its satellites,…
Great Balls of FIRE I: The formation of star clusters across cosmic time in a Milky Way-mass galaxy
Michael Y. Grudić, Zachary Hafen, Carl L. Rodriguez +5
The properties of young star clusters formed within a galaxy are thought to vary in different interstellar medium (ISM) conditions, but the details of this mapping from galactic to…
Cluster assembly and the origin of mass segregation in the STARFORGE simulations
Dávid Guszejnov, Carleen Markey, Stella S. R. Offner +4
Stars form in dense, clustered environments, where feedback from newly formed stars eventually ejects the gas, terminating star formation and leaving behind one or more star cluste…
The dynamics and outcome of star formation with jets, radiation, winds, and supernovae in concert
Michael Y. Grudić, Dávid Guszejnov, Stella S. R. Offner +4
We analyze the first giant molecular cloud (GMC) simulation to follow the formation of individual stars and their feedback from jets, radiation, winds, and supernovae, using the ST…
Less wrong: a more realistic initial condition for simulations of turbulent molecular clouds
Henry B. Lane, Michael Y. Grudić, Dávid Guszejnov +3
Simulations of isolated giant molecular clouds (GMCs) are an important tool for studying the dynamics of star formation, but their turbulent initial conditions (ICs) are uncertain.…
STARFORGE: Toward a comprehensive numerical model of star cluster formation and feedback
Michael Y. Grudić, Dávid Guszejnov, Philip F. Hopkins +2
We present STARFORGE (STAR FORmation in Gaseous Environments): a new numerical framework for 3D radiation MHD simulations of star formation that simultaneously follow the formation…
STARFORGE: The effects of protostellar outflows on the IMF
Dávid Guszejnov, Michael Y. Grudić, Philip F. Hopkins +2
The initial mass function (IMF) of stars is a key quantity affecting almost every field of astrophysics, yet it remains unclear what physical mechanisms determine it. We present th…
Can magnetized turbulence set the mass scale of stars?
David Guszejnov, Michael Y. Grudić, Philip F. Hopkins +2
Understanding the evolution of self-gravitating, isothermal, magnetized gas is crucial for star formation, as these physical processes have been postulated to set the initial mass…
