Deep Search For Molecular Oxygen in TW Hya
Becky J. Williams, L. Ilsedore Cleeves, Christian Eistrup +1
The dominant form of oxygen in cold molecular clouds is gas-phase carbon monoxide (CO) and ice-phase water (HO). Yet, in planet-forming disks around young stars, gas-phase CO a…
Global Hydromagnetic Simulations of Protoplanetary Disks with Stellar Irradiation and Simplified Thermochemistry
Oliver Gressel, Jon P. Ramsey, Christian Brinch +3
Outflows driven by large-scale magnetic fields likely play an important role in the evolution and dispersal of protoplanetary disks, and in setting the conditions for planet format…
Pebble dynamics and accretion onto rocky planets. II. Radiative models
Andrius Popovas, Åke Nordlund, Jon P. Ramsey
We investigate the effects of radiative energy transfer on a series of nested-grid, high-resolution hydrodynamic simulations of gas and particle dynamics in the vicinity of an Eart…
Pebble dynamics and accretion onto rocky planets. I. Adiabatic and convective models
A. Popovas, Å. Nordlund, Jon P. Ramsey +1
We present nested-grid, high-resolution hydrodynamic simulations of gas and particle dynamics in the vicinity of Mars- to Earth-mass planetary embryos. The simulations extend from…
A quantification of hydrodynamical effects on protoplanetary dust growth
E. Sellentin, J. P. Ramsey, F. Windmark +1
Context. The growth process of dust particles in protoplanetary disks can be modeled via numerical dust coagulation codes. In this approach, physical effects that dominate the dust…
