Giant Planet Formation by Disk Instability: A Comparison Simulation With An Improved Radiative Scheme
Kai Cai, Megan K. Pickett, Richard H. Durisen +1
There has been disagreement currently about whether cooling in protoplanetary disks can be sufficiently fast to induce the formation of gas giant protoplanets via gravitational ins…
The Formation of Fragments at Corotation in Isothermal Protoplanetary Disks
Richard H. Durisen, Thomas W. Hartquist, Megan K. Pickett
Numerical hydrodynamics simulations have established that disks which are evolved under the condition of local isothermality will fragment into small dense clumps due to gravitatio…
The Effects of Metallicity and Grain Size on Gravitational Instabilities in Protoplanetary Disks
Kai Cai, Richard H. Durisen, Scott Michael +4
Observational studies show that the probability of finding gas giant planets around a star increases with the star's metallicity. Our latest simulations of disks undergoing gravita…
A Possible Hybrid Scenario for Gas Giant Planet Formation in Rings
Richard H. Durisen, Kai Cai, Annie C. Mejia +1
The core-accretion mechanism for gas giant formation may be too slow to create all observed gas giant planets during reasonable gas disk lifetimes, but it has yet to be firmly esta…
Gravitational Instabilities in Disks with Radiative Cooling
Annie C. Mejía, Richard H. Durisen, Megan K. Pickett
Previous simulations of self-gravitating protostellar disks have shown that, once developed, gravitational instabilities are enhanced by cooling the disk constantly during its evol…
