Late-infall-induced formation of giant planets, multigenerational planetesimals, and disk substructures
Haichen Zhao, Tommy Chi Ho Lau, Joanna Drążkowska +2
Late infall can replenish the building materials of planets in protoplanetary disks and dramatically alter their structural evolution. The resulting pressure bumps effectively accu…
Planetesimal Formation Across the Stellar Mass Spectrum and its Influence on Exoplanet-Inherited Volatile Budgets
Joe Williams, Sebastiaan Krijt, Joanna Drążkowska +1
Protoplanetary discs emerging from collapsing molecular clouds are capable of forming planetesimals at the water snowline during both the cloud collapse and Class II disc phases; s…
Complex gas flows in magnetized protoplanetary disks promote the formation of dust traps at low fragmentation velocities
Vignesh Vaikundaraman, Joanna Drazkowska, Nerea Gurrutxaga +1
Non-ideal magnetohydrodynamic simulations of protoplanetary disks show a plethora of complex gas structures, including winds, rings, and gaps. These affect dust transport and help…
A Monte Carlo method for tracking dust properties during coagulation in protoplanetary disks
Nerea Gurrutxaga, Vignesh Vaikundaraman, Joanna Drazkowska
Dust growth is a crucial step in planet formation, and the efficiency of this process is controlled by the physical and chemical properties of the dust grains. Monte Carlo-based me…
Carbonaceous Chondrites provide evidence for late-stage planetesimal formation in a pressure bump
Nerea Gurrutxaga, Joanna Drazkowska, Vignesh Vaikundaraman +1
Carbonaceous chondrites are samples from planetesimals that formed 2-4 million years after solar system formation began. They consist of distinct dust components formed at differen…
Dust evolution during protoplanetary disk buildup enhances CO ice relative to water
Joanna Drazkowska
Water ice is expected to be the dominant volatile component of bodies formed in the outer Solar System. However, recent observations of comets and trans-Neptunian objects suggest t…
Effects of Stellar X-ray Photoevaporation on Planetesimal Formation via the Streaming Instability
Xuchu Ying, Beibei Liu, Haifeng Yang +7
The formation of planetesimals via the streaming instability (SI) is a crucial step in planet formation, yet its triggering conditions and efficiency are highly sensitive to both d…
Formation of Multiple Dynamical Classes in the Kuiper Belt via Disk Dissipation
Tommy Chi Ho Lau, Til Birnstiel, Sebastian Markus Stammler +1
Planetesimal formation likely lasted for millions of years in the solar nebula, and the cold classicals in the Kuiper Belt are suggested to be the direct products of streaming inst…
Can Close-In Exoplanets form by Pebble Accretion?
Jayashree Narayan, Joanna Drazkowska, Vignesh Vaikundaraman
Pebble accretion is the leading theory for the formation of exoplanets more massive than the Earth. Many parameters influence planet growth in the pebble accretion models. In this…
Refractory carbon depletion by photolysis through dust collisions and vertical mixing
Vignesh Vaikundaraman, Joanna Drazkowska, Fabian Binkert +2
The inner Solar System is depleted in refractory carbon in comparison to the interstellar medium and the depletion likely took place in the protoplanetary disk phase of the Solar S…
The early Solar System and its meteoritical witnesses
Emmanuel Jacquet, Cornelis Dullemond, Joanna Drążkowska +1
Meteorites, and in particular primitive meteorites (chondrites), are irreplaceable probes of the solar protoplanetary disk. We review their essential properties and endeavour to pl…
CAI formation in the early Solar System
P. Woitke, J. Drażkowska, H. Lammer +2
Ca-Al-rich inclusions (CAIs) are the oldest dated solid materials in the solar system, found as light-coloured crystalline ingredients in meteorites. Their formation time is common…
Origin of isotopic diversity among carbonaceous chondrites
Jan L. Hellmann, Jonas M. Schneider, Elias Wölfer +5
Carbonaceous chondrites are some of the most primitive meteorites and derive from planetesimals that formed a few million years after the beginning of the solar system. Here, using…
Rapid Formation of Exoplanetesimals Revealed by White Dwarfs
A. Bonsor, T. Lichtenberg, J. Drazkowska +1
The timing of formation for the first planetesimals determines the mode of planetary accretion and their geophysical and compositional evolution. Astronomical observations of circu…
Planet Formation Theory in the Era of ALMA and Kepler: from Pebbles to Exoplanets
Joanna Drazkowska, Bertram Bitsch, Michiel Lambrechts +7
Our understanding of planet formation has been rapidly evolving in recent years. The classical planet formation theory, developed when the only known planetary system was our own S…
Why do M dwarfs have more transiting planets?
Gijs D. Mulders, Joanna Drążkowska, Nienke van der Marel +2
We propose a planet formation scenario to explain the elevated occurrence rates of transiting planets around M dwarfs compared to sun-like stars discovered by Kepler. We use a pebb…
Bifurcation of planetary building blocks during Solar System formation
Tim Lichtenberg, Joanna Drazkowska, Maria Schönbächler +2
Geochemical and astronomical evidence demonstrate that planet formation occurred in two spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We u…
How dust fragmentation may be beneficial to planetary growth by pebble accretion
Joanna Drazkowska, Sebastian M. Stammler, Til Birnstiel
Pebble accretion is an emerging paradigm for the fast growth of planetary cores. Pebble flux and pebble sizes are the key parameters used in the pebble accretion models. We aim to…
Planet-induced Vortices with Dust Coagulation in Protoplanetary Disks
Ya-Ping Li, Hui Li, Shengtai Li +3
In this work, we study how the dust coagulation/fragmentation will influence the evolution and observational appearances of vortices induced by a massive planet embedded in a low v…
Ring Morphology with Dust Coagulation in Protoplanetary Disks
JT Laune, Hui Li, Shengtai Li +5
Tidal interactions between the embedded planets and their surrounding protoplanetary disks are often postulated to produce the observed complex dust substructures, including rings,…
Including Dust Coagulation in Hydrodynamic Models of Protoplanetary Disks: Dust Evolution in the Vicinity of a Jupiter-mass Planet
Joanna Drazkowska, Shengtai Li, Til Birnstiel +2
Dust growth is often neglected when building models of protoplanetary disks due to its complexity and computational expense. However, it does play a major role in shaping the evolu…
The DSHARP Rings: Evidence of Ongoing Planetesimal Formation?
Sebastian M. Stammler, Joanna Drazkowska, Til Birnstiel +3
Recent high-resolution interferometric observations of protoplanetary disks at (sub-)millimeter wavelengths reveal omnipresent substructures, such as rings, spirals, and asymmetrie…
Gas accretion damped by dust back-reaction at the snow line
Matías Gárate, Til Birnstiel, Joanna Drazkowska +1
Context. The water snowline divides dry and icy solid material in protoplanetary disks, and has been thought to significantly affect planet formation at all stages. If dry particle…
Effects of Ringed Structures and Dust Size Growth on Millimeter Observations of Protoplanetary Disks
