Fragmentation-limited dust filtration in 2D simulations of planet-disk systems with dust coagulation. Parameter study and implications for the inner disk's dust mass budget and composition

Thomas Pfeil, Philip J. Armitage, Yan-Fei Jiang

Super-thermal gas giant planets or their progenitor cores are known to open deep gaps in protoplanetary disks, which stop large, drifting dust particles on their way to the inner d…

Multi-band Emission from Star-Disk Collision and Implications for Quasi-Periodic Eruptions

Xiaoshan Huang, Itai Linial, Yan-Fei Jiang

We perform two-dimensional, multi-group radiation hydrodynamic simulations to explore the observational properties of a solar-like star colliding with an accretion disk around a su…

Radiation-magnetohydrodynamic Simulations of Accretion Flow Formation After a Tidal Disruption Event

Maria Renee Meza, Xiaoshan Huang, Shane W. Davis +1

We perform 3D radiation-magnetohydrodynamic simulations of the evolution of the fallback debris after a tidal disruption event. We focus on studying the effects of magnetic fields…

Radiative magnetohydrodynamics simulation of minidisks in equal-mass massive black hole binaries

Chi-Ho Chan, Vishal Tiwari, Tamara Bogdanović +2

We are on the cusp of detecting gravitational waves (GWs) from individual massive black hole binaries (MBHBs) with the Laser Interferometer Space Antenna and pulsar-timing arrays.…

Radiation Magnetohydrodynamic Simulation of sub-Eddington Circumbinary Disk around an Equal-mass Massive Black Hole Binary

Vishal Tiwari, Chi-Ho Chan, Tamara Bogdanović +3

We present the first three-dimensional radiation magnetohydrodynamic (RMHD) simulation of a sub-Eddington circumbinary disk (CBD) around an equal-mass massive black hole binary (MB…

Time-Dependent Radiation Transport Simulations of Infrared Echoes from Dust-Shrouded Luminous Transients

Semih Tuna, Brian D. Metzger, Yan-Fei Jiang +1

A wide range of stellar explosions, including supernovae (SNe), tidal disruption events (TDE), and fast blue optical transients (FBOT), can occur in dusty environments initially op…

Continuum Reverberation in Active Galactic Nuclei Disks Only With Sufficient X-ray Luminosity and Low Albedo

Amy Secunda, Yan-Fei Jiang, Jenny E. Greene

Disk continuum reverberation mapping is one of the primary ways we learn about active galactic nuclei (AGN) accretion disks. Reverberation mapping assumes that time-varying X-rays…

Circumplanetary Disks are Rare around Planets at Large Orbital Radii: A Parameter Survey of Flow Morphology around Giant Planets

Sabina Sagynbayeva, Rixin Li, Aleksandra Kuznetsova +3

We investigate how the formation and structure of circumplanetary disks (CPDs) varies with planet mass and protoplanetary disk aspect ratio. Using static mesh refinement and a near…

Radiation Hydrodynamic Simulations of Massive Stars in Gas-rich Environments: Accretion of AGN Stars Suppressed By Thermal Feedback

Yi-Xian Chen, Yan-Fei Jiang, Jeremy Goodman +1

Massive stars may form in or be captured into AGN disks. Recent 1D studies employing stellar-evolution codes have demonstrated the potential for rapid growth of such stars through…

Cosmic-Ray Transport in Varying Galactic Environments

Lucia Armillotta, Eve C. Ostriker, Yan-Fei Jiang

We study the propagation of mildly-relativistic cosmic rays (CRs) in multiphase interstellar medium environments with conditions typical of nearby disk galaxies. We employ the tech…

An Implicit Finite Volume Scheme to Solve the Time Dependent Radiation Transport Equation Based on Discrete Ordinates

Yan-Fei Jiang

We describe a new algorithm to solve the time dependent, frequency integrated radiation transport (RT) equation implicitly, which is coupled to an explicit solver for equations of…

Convectively Driven Three Dimensional Turbulence in Massive Star Envelopes: I. A 1D Implementation of Diffusive Radiative Transport

William Schultz, Lars Bildsten, Yan-Fei Jiang

Massive (M) stars exhibit luminosities that are near the Eddington-limit for electron scattering causing the increase in opacity associated with iron at $T\appro…

Opacity Driven Convection and Variability in Accretion Disks around Supermassive Black Holes

Yan-Fei Jiang, Omer Blaes

We study the structure of accretion disks around supermassive black holes in the radial range gravitational radii, using a three dimensional radiation magneto-hydrodyn…
