From spirals to rings: dust dynamics in gravitoturbulent protoplanetary discs after late infall
Clément Baruteau, Steven Rendon Restrepo, Gaylor Wafflard-Fernandez +7
Substructures appear to be a common trait of all extended protoplanetary discs. They are found notably in discs still surrounded by ambient, possibly infalling material. In this st…
The ALMA View of the Edge-on Gomez's Hamburger System: A Highly-Dynamic, Asymmetric Protoplanetary Disk Reveals the Earliest Phases of Giant Planet Formation
Charles J. Law, Jensen Lawrence, Richard Teague +18
Chemical tracers provide some of the strongest observational signatures of ongoing planet formation and localized dynamical perturbations in protoplanetary disks. In particular, su…
Dust Morphology Under Changing Dust Mass Ratios in Protoplanetary Discs
Matthew Murray, Cassandra Hall, Hans Baehr +1
Protoplanetary disc mass is one of the most fundamental properties of a planet-forming system, as it sets the total mass budget available for planet formation. However, obtaining d…
On the Gravitational Collapse of Small Dust Grains in Self-gravitating Disk Structures
Hans Baehr, Ken Rice, Chao-Chin Yang +1
Planet formation may begin much earlier than previously expected, when the protoplanetary disk is still massive and gravitationally unstable. It has been proposed that solid grains…
Entropy and diffusion characterize mutation accumulation and biological information loss
Stephan Baehr, Hans Baehr
Aging is a universal consequence of life, yet researchers have identified no universal theme. This manuscript considers aging from the perspective of entropy, wherein things fall a…
Dust density enhancements and the direct formation of planetary cores in gravitationally unstable discs
Ken Rice, Hans Baehr, Alison K Young +5
Planet formation via core accretion involves the growth of solids that can accumulate to form planetary cores. There are a number of barriers to the collisional growth of solids in…
Turbulence Inhibits Planetesimal Formation in Class 0/I Disks Subject to Infall
Daniel Carrera, Abigail Davenport, Jacob B. Simon +5
There is growing evidence that planet formation begins early, within the Myr Class 0/I phase, when infall dominates disk dynamics. Our goal is to determine if Class 0/I…
Filling in the Gaps: Can Gravitationally Unstable Discs Form the Seeds of Gas Giant Planets?
Hans Baehr
Circumstellar discs likely have a short window when they are self-gravitating and prone to the effects of disc instability, but during this time the seeds of planet formation can b…
Thermal instabilities in accretion disks II: Numerical Experiments for the Goldreich-Schubert-Fricke Instability and the Convective Overstability in disks around young stars
Hubert Klahr, Hans Baehr, Julio David Melon Fuksman
The linear stability analysis of a stratified rotating fluid (see paper I) showed that disks with a baroclinic stratification under the influence of thermal relaxation will become…
Direct Formation of Planetary Embryos in Self-Gravitating Disks
Hans Baehr, Zhaohuan Zhu, Chao-Chin Yang
Giant planets have been discovered at large separations from the central star. Moreover, a striking number of young circumstellar disks have gas and/or dust gaps at large orbital s…
The Role of the Cooling Prescription for Disk Fragmentation: Numerical Convergence & Critical Cooling Parameter in Self-Gravitating Disks
Hans Baehr, Hubert Klahr
Protoplanetary disks fragment due to gravitational instability when there is enough mass for self-gravitation, described by the Toomre parameter, and when heat can be lost at a rat…
