A Global 3-D Simulation of Magnetospheric Accretion: I. Magnetically Disrupted Disks and Surface Accretion
Zhaohuan Zhu, James M. Stone, Nuria Calvet
We present a 3-D ideal MHD simulation of magnetospheric accretion onto a non-rotating star. The accretion process unfolds with intricate 3-D structures driven by various mechanisms…
Resolving the Binary Components of the Outbursting Protostar HBC 494 with ALMA
Pedro Henrique Nogueira, Alice Zurlo, Sebastián Pérez +15
Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevat…
Effective two-body scatterings around a massive object
Yihan Wang, Saavik Ford, Rosalba Perna +3
Two-body scatterings under the potential of a massive object are very common in astrophysics. If the massive body is far enough away that the two small bodies are in their own grav…
Large-scale CO spiral arms and complex kinematics associated with the T Tauri star RU Lup
Jane Huang, Sean M. Andrews, Karin I. Öberg +9
While protoplanetary disks often appear to be compact and well-organized in millimeter continuum emission, CO spectral line observations are increasingly revealing complex behavior…
A Study of Millimeter Variability in FUor Objects
John Wendeborn, Catherine C. Espaillat, Enrique Macias +6
FU Orionis objects (FUors) are rapidly-accreting, pre-main sequence objects that are known to exhibit large outbursts at optical and near-infrared wavelengths, with post-eruption,…
A triple star system with a misaligned and warped circumstellar disk shaped by disk tearing
Stefan Kraus, Alexander Kreplin, Alison K. Young +29
Young stars are surrounded by a circumstellar disk of gas and dust, within which planet formation can occur. Gravitational forces in multiple star systems can disrupt the disk. The…
