Soot Planets instead of Water Worlds
Jie Li, Edwin A. Bergin, Marc M. Hirschmann +3
Some low-density exoplanets are thought to be water-rich worlds that formed beyond the snow line of their protoplanetary disc, possibly accreting coequal portions of rock and water…
Burned to ashes: How the thermal decomposition of refractory organics in the inner protoplanetary disc impacts the gas-phase C/O ratio
Adrien Houge, Anders Johansen, Edwin Bergin +5
The largest reservoir of carbon in protoplanetary discs is stored in refractory organics, which thermally decompose into the gas-phase at the organics line, well interior to the wa…
Dynamics of small, constant size particles in a protoplanetary disk with an embedded protoplanet
Ellen M. Price, Eric Van Clepper, Fred J. Ciesla
Hydrodynamical simulations of protoplanetary disk dynamics are useful tools for understanding the formation of planetary systems, including our own. Approximations are necessary to…
Three-dimensional transport of solids in a protoplanetary disk containing a growing giant planet
Eric Van Clepper, Ellen M. Price, Fred J. Ciesla
We present the results of combined hydrodynamic and particle tracking post-processing modeling to study the transport of small dust in a protoplanetary disk containing an embedded…
JWST/MIRI detection of a carbon-rich chemistry in a solar nebula analog
Maria Jose Colmenares, Edwin Bergin, Colette Salyk +16
It has been proposed, and confirmed by multiple observations, that disks around low mass stars display a molecule-rich emission and carbon-rich disk chemistry as compared to their…
Quantifying the high early solar cosmic ray flux with cosmogenic neon isotopes in refractory minerals
Xin Yang, Fred J. Ciesla, Philipp R. Heck
An enhancement in the activity of the early young Sun resulting in a high charged particle flux has been invoked to explain excesses in spallation-induced nuclides in primitive pla…
