Radiation Magneto-hydrodynamic Simulations of MRI with Zero-Net-Vertical-Flux: Necessity of Resolving the Thermal Scale For Strongly Magnetized Initial Conditions
Yi-Xian Chen, Yan-Fei Jiang, Jeremy Goodman
We perform 3D radiation magneto-hydrodynamic (RMHD) shearing-box simulations of local patches of optically thick accretion disks, applicable to sub-Eddington active galactic nuclei…
Observation of nonaxisymmetric standard magnetorotational instability induced by a free-shear layer
Yin Wang, Fatima Ebrahimi, Hongke Lu +3
The standard magnetorotational instability (SMRI) is widely believed to be responsible for the observed accretion rates in astronomical disks. It is a linear instability triggered…
Surprising Spin-orbit Resonances of Rocky Planets
Henry Yuan, Yubo Su, Jeremy Goodman
Recent works suggest that, in multiplanetary systems, a close-in exoplanet can sometimes avoid becoming tidally locked to its host star if it is captured into a secular spin-orbit…
Constraining Protoplanetary Disk Winds from Forbidden Line Profiles with Simulation-based Inference
Ahmad Nemer, ChangHoon Hahn, Jiaxuan Li +2
Protoplanetary disks are the sites of vigorous hydrodynamic processes, such as accretion and outflows, and ultimately establish the conditions for the formation of planets. The pro…
Photoevaporation from Inner Protoplanetary Disks Confronted with Observations
Yiren Lin, Lile Wang, Min Fang +2
The decades-long explorations on the dispersal of protoplanetary disks involve many debates about photoevaporation versus magnetized wind launching mechanisms. This letter argues t…
Line profiles of forbidden emission lines and what they can tell us about protoplanetary disk winds
Ahmad Nemer, Jeremy Goodman
Emission in forbidden lines of oxygen, neon, and other species are commonly used to trace winds from protoplanetary disks. Using Cloudy, we calculate such emission for parametrized…
Non-ideal Magnetohydrodynamic Instabilities in Protoplanetary Disks: Vertical Modes and Reflection Asymmetry
Lile Wang, Sheng Xu, Zhenyu Wang +2
Magnetized disk winds and wind-driven accretion are an essential and intensively studied dispersion mechanism of protoplanetary disks. However, the stability of these mechanisms ha…
Magnetorotational Instability in a Swirling Partially Ionized Gas
Amy Secunda, Peter Donnel, Hantao Ji +1
The magnetorotational instability (MRI) has been proposed as the method of angular momentum transport that enables accretion in astrophysical discs. However, for weakly-ionized dis…
Identification of a non-axisymmetric mode in laboratory experiments searching for standard magnetorotational instability
Yin Wang, Erik P. Gilson, Fatima Ebrahimi +4
The standard magnetorotational instability (SMRI) is a promising mechanism for turbulence and rapid accretion in astrophysical disks. It is a magnetohydrodynamic (MHD) instability…
