Exploring the conditions for forming planetesimals by the streaming instability and planetary systems by pebble accretion
Anders Johansen, Wladimir Lyra
The streaming instability and pebble accretion are two physical mechanisms with demonstrated potentials to drive, respectively, the formation of planetesimals and the growth of pla…
How leaky? A large parameter study of leaky dust traps to quantify the transport of pebbles and ice in protoplanetary discs
Adrien Houge, Anders Johansen, Andrea Banzatti +1
In protoplanetary discs, the presence of dust traps can significantly alter the transport of solids from the outer to the inner regions, and hence they are often invoked as an expl…
Magnetohydrodynamic simulation assessment of a potential near-ultraviolet early ingress in WASP-189b
Y. Duann, S. -H. Lai, H. J. Hoeijmakers +8
Ultra-hot Jupiters (UHJs) in close orbits around early-type stars provide natural laboratories for studying atmospheric escape and star-planet interactions under extreme irradiatio…
The cosmic journey of dust grains -- from nucleation to planetary system
Kira Lund, Anders Johansen, Oscar Agertz
Dust is essential to the evolution of galaxies and drives the formation of planetary systems. The challenge of inferring the origin of different presolar dust grains from meteoriti…
The coexistence of the streaming instability and the vertical shear instability in protoplanetary disks: Scale-dependence of dust diffusion
Urs Schäfer, Anders Johansen, Mario Flock
The vertical shear instability and the streaming instability are two robust sources of turbulence in protoplanetary disks. The former has been found to induce anisotropic turbulenc…
Thousands of planetesimals: Simulating the streaming Instability in very large computational domains
Urs Schäfer, Anders Johansen, Troels Haugbølle +1
The streaming instability is a mechanism whereby pebble-sized particles in protoplanetary discs spontaneously come together in dense filaments, which collapse gravitationally to fo…
