exoALMA VII: Benchmarking Hydrodynamics and Radiative Transfer Codes
Jaehan Bae, Mario Flock, Andres Izquierdo +25
Forward modeling is often used to interpret substructures observed in protoplanetary disks. To ensure the robustness and consistency of the current forward modeling approach from t…
Modeling protoplanetary disk heating by planet-induced spiral shocks
Tomohiro Ono, Tatsuki Okamura, Satoshi Okuzumi +1
We investigate the heating of protoplanetary disks caused by shocks associated with spiral density waves induced by an embedded planet. Using two-dimensional hydrodynamical simulat…
Kinematic signatures of a low-mass planet with a moderately inclined orbit in a protoplanetary disk
Kazuhiro D. Kanagawa, Tomohiro Ono, Munetake Momose
A planet embedded in a protoplanetary disk produces a gap by disk-planet interaction. It also generates velocity perturbation of gas, which can also be observed as deviations from…
Two saturated states of the vertical shear instability in protoplanetary disks with vertically varying cooling times
Yuya Fukuhara, Satoshi Okuzumi, Tomohiro Ono
Turbulence in protoplanetary disks plays an important role in dust evolution and planetesimal formation. The vertical shear instability (VSI) is one of the candidate hydrodynamic m…
Cooling-Induced Vortex Decay in Keplerian Disks
Jeffrey Fung, Tomohiro Ono
Vortices are readily produced by hydrodynamical instabilities, such as the Rossby wave instability, in protoplanetary disks. However, large-scale asymmetries indicative of dust-tra…
Effects of Dust Evolution on the Vertical Shear Instability in the Outer Regions of Protoplanetary Disks
Yuya Fukuhara, Satoshi Okuzumi, Tomohiro Ono
The vertical shear instability (VSI) is a hydrodynamical instability that requires rapid gas cooling and has been suggested to operate in outer regions of protoplanetary disks. The…
ALMA observation of the protoplanetary disk around WW Cha: faint double-peaked ring and asymmetric structure
Kazuhiro D. Kanagawa, Jun Hashimoto, Takayuki Muto +13
We present Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 observations of dust continuum emission of the disk around WW Cha. The dust continuum image shows a smooth dis…
GW Ori: Interactions Between a Triple-star System and its Circumtriple Disk in Action
Jiaqing Bi, Nienke van der Marel, Ruobing Dong +17
GW Ori is a hierarchical triple system which has a rare circumtriple disk. We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of 1.3 mm dust continuum and…
Parametric Study of the Rossby Wave Instability in a Two-dimensional Barotropic Disk II: Non-Linear Calculations
Tomohiro Ono, Takayuki Muto, Kengo Tomida +1
Vortices in protoplanetary disks have attracted attention since the discovery of lopsided structures. One of the possible mechanisms for producing vortices is the Rossby Wave Insta…
Parametric Study of the Rossby Wave Instability in a Two-Dimensional Barotropic Disk
Tomohiro Ono, Takayuki Muto, Taku Takeuchi +1
Protoplanetary disks with non-axisymmetric structures have been observed. The Rossby wave instability (RWI) is considered as one of the origins of the non-axisymmetric structures.…
Rotational Instability in the Outer Region of Protoplanetary Disks
Tomohiro Ono, Hideko Nomura, Taku Takeuchi
We analytically calculate the marginally stable surface density profile for rotational instability of protoplanetary disks. The derived profile can be utilized for considering the…
