Survival of planet-induced vortices in 2D disks

Thomas Rometsch et al.

Summary: Through 2D numerical simulations, we find that vortices generated at the outer gap edge can survive for approximately 100-3000 planetary orbits, with the shortest lifetimes occurring under moderately efficient dissipation and cooling. Additionally, we observe long-lasting vortices with lifetimes of at least 15,000 orbits under very low viscosity and very short thermal relaxation timescales. Disk self-gravity significantly impacts vortex lifetimes, allowing both regular and long-lived vortices to persist.

Thresholds for Particle Clumping by the Streaming Instability

Rixin Li et al.

Summary: The streaming instability is a mechanism in protoplanetary disks that aerodynamically concentrates solid particles to trigger planetesimal formation. The critical metallicity depends on particle size and disk conditions, and a sharp increase in critical metallicity is observed for small solids when the dimensionless stopping time is <= 0.01. Our study widens the parameter space for the streaming instability to trigger planetesimal formation.

Cooling-induced Vortex Decay in Keplerian Disks

Jeffrey Fung et al.

Summary: This study investigates how radiative cooling affects the decay of elliptical vortices in protoplanetary disks, finding that the vortex lifetime may be determined by the ratio of cooling time to turnaround time.

Polydisperse streaming instability - II. Methods for solving the linear stability problem

Sijme-Jan Paardekooper et al.

Summary: The paper presents a new approach to streaming instabilities, allowing for more accurate solutions to linear stability problems with lower computational costs. It also demonstrates techniques for reducing integral equations to complex polynomials and counting roots of dispersion relations inside contours. The methods described can reproduce and surpass the accuracy of previous results in the literature.

Polydisperse streaming instability - III. Dust evolution encourages fast instability

Colin P. McNally et al.

Summary: Research suggests that the evolution of dust plays a significant role in triggering streaming instability during planet formation. The enhancement of larger dust sizes through reasonable collisional dust evolution may be sufficient to produce instability behavior similar to the monodisperse case. Local enhancement of the dust to gas volume mass density ratio to order unity is also necessary.

Which planets trigger longer lived vortices: low-mass or high-mass?

Michael Hammer et al.

Summary: Studies have shown that low-mass planets in some protoplanetary discs can trigger multiple generations of vortices leading to dust asymmetries, while vortices with H/r = 0.08 exhibit longer survival periods. These results help explain certain observed phenomena in celestial bodies.

A major asymmetric ice trap in a planet-forming disk: II. Prominent SO and SO2 pointing to C/O < 1

Alice S. Booth et al.

Summary: Gas-phase sulphur-bearing volatiles are found to be significantly reduced in protoplanetary disks, indicating a high C/O ratio in the warm molecular layer where giant planets form their atmospheres. Detection of SO and SO2 emissions in the Oph-IRS 48 disk through ALMA suggests a spatial correlation with the asymmetric dust trap, possibly due to sublimation of ices at the edge of the dust cavity. The observed molecules could potentially contribute to a significant portion of the total volatile sulphur budget in the disk, and the constrained C/O ratio has important implications for planetary elemental compositions within warm transition disk cavities.

Stratified and Vertically Shearing Streaming Instabilities in Protoplanetary Disks

Min-Kai Lin

Summary: The research suggests that the streaming instability between dust and gas in protoplanetary disks can be captured through vertically global linear stability analyses, driven primarily by the vertical gradient in the rotation velocity of the dust-gas mixture and requiring partial coupling. This helps in understanding the mechanism of planetesimal formation.

On the Diversity of Asymmetries in Gapped Protoplanetary Disks

Nienke van der Marel et al.

Summary: Research suggests that the asymmetry in protoplanetary disks is mainly associated with higher Stokes numbers or low gas surface density. The gas gap radius is approximately 2 times smaller than the dust ring radius, indicating that the companions in these disks have estimated masses ranging from 15-50 M_Jup or 3-15 M_Jup, and are in eccentric orbits.
