Planetesimal Formation Across the Stellar Mass Spectrum and its Influence on Exoplanet-Inherited Volatile Budgets
Joe Williams, Sebastiaan Krijt, Joanna DrÄ Å¼kowska +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…
Late-infall-induced formation of giant planets, multi-generational planetesimals, and disk substructures
Haichen Zhao, Tommy Chi Ho Lau, Joanna DrÄ Å¼kowska +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…
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…
