The Role of Ice Compositions for Snowlines and the C/N/O Ratios in Active Disks
Ana-Maria A. Piso, Jamila Pegues, Karin I. Oberg
The elemental compositions of planets define their chemistry, and could potentially be used as beacons for their formation location if the elemental gas and grain ratios of planet…
C/O and Snowline Locations in Protoplanetary Disks: The Effect of Radial Drift and Viscous Gas Accretion
Ana-Maria A. Piso, Karin I. Oberg, Tilman Birnstiel +1
The C/O ratio is a defining feature of both gas giant atmospheric and protoplanetary disk chemistry. In disks, the C/O ratio is regulated by the presence of snowlines of major vola…
Minimum Core Masses for Giant Planet Formation With Realistic Equations of State and Opacities
Ana-Maria A. Piso, Andrew N. Youdin, Ruth A. Murray-Clay
Giant planet formation by core accretion requires a core that is sufficiently massive to trigger runaway gas accretion in less that the typical lifetime of protoplanetary disks. We…
On the Minimum Core Mass for Giant Planet Formation at Wide Separations
Ana-Maria A. Piso, Andrew N. Youdin
In the core accretion hypothesis, giant planets form by gas accretion onto solid protoplanetary cores. The minimum (or critical) core mass to form a gas giant is typically quoted a…
