  journal={Nature Astronomy},
Intermediate-mass planets, from super-Earth to Neptune-sized bodies, are the most common types of planet in the Galaxy1. The prevailing theory of planet formation—core accretion2—predicts the existence of substantially fewer intermediate-mass giant planets than have been observed3,4. The competing mechanism for planet formation—disk instability—can produce massive gas giant planets on wide orbits, such as HR 87995, by direct fragmentation of the protoplanetary disk6. Previously, fragmentation… 
Standing Solitary Waves as Transitions to Spiral Structures in Gravitationally Unstable Accretion Disks
Astrophysical disks that are sufficiently cold and dense are linearly unstable to the formation of axisymmetric rings as a result of the disk’s gravity. In practice, spiral structures are formed,
Molecules with ALMA at Planet-forming Scales (MAPS): A Circumplanetary Disk Candidate in Molecular-line Emission in the AS 209 Disk
We report the discovery of a circumplanetary disk (CPD) candidate embedded in the circumstellar disk of the T Tauri star AS 209 at a radial distance of about 200 au (on-sky separation of 1.″4 from
The Communication Infrastructures of Living Systems and the Universe: Analysis from the Perspective of Antenna Theory
It is still unknown how molecules coordinate their activity and operate at high speeds in the crowded environment of a cell. The study focuses on the geometry of biomolecules, assuming B-DNA,

While collisional accumulation is nearly universally accepted as the formation mechanism of rock and ice worlds, the situation regarding gas giant planet formation is more nuanced. Gas accretion by


Rapid Formation of Outer Giant Planets by Disk Instability
The formation mechanism of the ice giant planets is uncertain. A new hypothesis envisions rapid formation of several gaseous protoplanets in a marginally gravitationally unstable protoplanetary disk,
The Earliest Stages of Star and Planet Formation: Core Collapse, and the Formation of Disks and Outflows
(Abridged) In this review we focus on the observations and theory of the formation of early disks and outflows, and their connections with the first phases of planet formation. Large rotationally
The Evolution of Gravitationally Unstable Protoplanetary Disks: Fragmentation and Possible Giant Planet Formation
We carry out a large set of very high resolution, three-dimensional, smoothed particle hydrodynamics simulations describing the evolution of gravitationally unstable gaseous protoplanetary disks. We
The effect of MHD turbulence on massive protoplanetary disk fragmentation
Massive disk fragmentation has been suggested to be one of the mechanisms leading to the formation of giant planets. While it has been heavily studied in quiescent hydrodynamic disks, the effect of
Characterization of migration in gravitationally unstable disks is necessary to understand the fate of protoplanets formed by disk instability. As part of a larger study, we are using a
The Two Modes of Gas Giant Planet Formation
I argue for two modes of gas giant planet formation and discuss the conditions under which each mode operates. Gas giant planets at disk radii r>100 AU are likely to form in situ by disk instability,
Global Simulations of Self-gravitating Magnetized Protoplanetary Disks
In the early stages of a protoplanetary disk, turbulence generated by gravitational instability (GI) should feature significantly in the disk’s evolution. At the same time, the disk may be
Evolution of the Solar Nebula. V. Disk Instabilities with Varied Thermodynamics
Disk instability is a promising mechanism for explaining the rapid formation of the gas and ice giant planets in our solar system as well as in extrasolar planetary systems. Disk instability involves
Circumplanetary discs around young giant planets: a comparison between core-accretion and disc instability
Circumplanetary discs can be found around forming giant planets, regardless of whether core accretion or gravitational instability built the planet. We carried out state-of-the-art hydrodynamical
