Young Planets around Young Accreting Stars: II. Circumplanetary Disk Formation and Accretion
Arturo Cevallos Soto, Zhaohuan Zhu
We present global 3-D ideal-MHD simulations of young giant planets in a protoplanetary disk (PPD) undergoing magnetospheric accretion onto its host star. Extending our previous wor…
Exoplanet System Architecture: Sculpting the Inner Regions
Mark R. Swain, Geoffrey Bryden, Jonathan C. Tan +14
In this study, we seek to improve our understanding of the competing roles of disk-driven and planet-planet dynamical migration in sculpting planetary system architecture in the in…
Modeling YSO Jets in 3D III: Dependence of Accretion and Jet Properties on Stellar Magnetospheric Field Strength and Rotation
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +1
Observations of Young Stellar Objects (YSOs) systems reveal a wide diversity of jet properties, from well-collimated bipolar jets to uni-polar jets and systems with no detectable j…
A tale of three tails: A misaligned streamer and mysterious structures around [BHB2007]1
Aashish Gupta, Antonio S. Hales, L. Ilsedore Cleeves +8
Recent discoveries of streamer-like structures around protostellar sources challenge the traditional picture of isolated, axisymmetric star formation. Here, we present new ALMA obs…
Hydrodynamical Simulations of Planet Rebound Migration in Photo-evaporating Disks
Beibei Liu, Clément Baruteau, Zhaohuan Zhu +2
This study investigates the orbital migration of a planet located near the truncated edge of protoplanetary disks, induced by X-ray photo-evaporation originating from the central s…
The ODYSSEUS Survey. Using accretion and stellar rotation to reveal the star-disk connection in T Tauri stars
Caeley V. Pittman, C. C. Espaillat, Zhaohuan Zhu +4
Classical T Tauri stars (CTTS) exhibit strong variability over timescales of minutes to decades. However, much theoretical work assumes that CTTS are in stable spin states. Here, w…
The ODYSSEUS Survey. Characterizing magnetospheric geometries and hotspot structures in T Tauri stars
Caeley V. Pittman, C. C. Espaillat, Connor E. Robinson +20
Magnetospheric accretion is a key process that shapes the inner disks of T Tauri stars, controlling mass and angular momentum evolution. It produces strong ultraviolet and optical…
Modeling YSO Jets in 3D II: Accretion-Fed, Star-Anchored Poynting Jets in the Low-Density Polar Cavity Powered by Disk-Magnetosphere Interaction
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +2
The origin of jets in young stellar objects (YSOs) remains a subject of active investigation. We present a 3D magnetohydrodynamic simulation of jet launching in YSOs, focusing on t…
Young Planets around Young Accreting Stars: I. Migration and Inner Stalling Orbits
Arturo Cevallos Soto, Zhaohuan Zhu
Planet migration within inner protoplanetary disks significantly influences exoplanet architectures. We investigate various migration mechanisms for young planets close to young st…
H Variability of AB Aur b with the Hubble Space Telescope: Probing the Nature of a Protoplanet Candidate with Accretion Light Echoes
Brendan P. Bowler, Yifan Zhou, Lauren I. Biddle +11
Giant planets generate accretion luminosity as they form. Much of this energy is radiated in strong H line emission, which has motivated direct imaging surveys at optical wavele…
Observational Signatures of Disk Winds in Protoplanetary Disks: Differentiating Magnetized and Photoevaporative Outflows With Fully Coupled Thermochemistry
Xiao Hu, Jaehan Bae, Zhaohuan Zhu +1
Magnetized winds and photoevaporative winds are critical in shaping protoplanetary disk evolution. Using 2D axisymmetric (magneto-)hydrodynamic simulations with Athena++ implementi…
A Survey of Protoplanetary Disks Using the Keck/NIRC2 Vortex Coronagraph
Nicole L. Wallack, Jean-Baptiste Ruffio, Garreth Ruane +34
Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations of protoplanetary disks in the millimeter continuum have shown a variety of radial gaps, cavities, and spira…
YSO Jets Magnetocentrifugally Driven by Reconnecting Atmospheric Avalanche Accretion Streams Above Inner Circumstellar Disks
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +2
Fast, collimated jets are ubiquitous features of young stellar objects (YSOs). They are generally thought to be powered by disk accretion, but the details are debated. Through 2D (…
3D Gap Opening in Non-Ideal MHD Protoplanetary Disks: Asymmetric Accretion, Meridional Vortices, and Observational Signatures
Xiao Hu, Zhi-Yun Li, Jaehan Bae +1
Recent high-angular resolution ALMA observations have revealed rich information about protoplanetary disks, including ubiquitous substructures and three-dimensional gas kinematics…
Fragmentation of Dense Rotation-Dominated Structures Fed by Collapsing Gravomagneto-Sheetlets and Origin of Misaligned 100 au-Scale Binaries and Multiple Systems
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +1
The majority of stars are in binary/multiple systems. How such systems form in turbulent, magnetized cores of molecular clouds in the presence of non-ideal MHD effects remains rela…
Self-consistent ring model in protoplanetary disks: temperature dips and substructure formation
Shangjia Zhang, Xiao Hu, Zhaohuan Zhu +1
Rings and gaps are ubiquitous in protoplanetary disks. Larger dust grains will concentrate in gaseous rings more compactly due to stronger aerodynamic drag. However, the effects of…
Inside-Out Planet Formation. IV. Pebble Evolution and Planet Formation Timescales
Xiao Hu, Jonathan C. Tan, Zhaohuan Zhu +4
Systems with tightly-packed inner planets (STIPs) are very common. Chatterjee & Tan proposed Inside-Out Planet Formation (IOPF), an in situ formation theory, to explain these plane…
