The Formation of Crystalline Dust in AGB Winds from Binary Induced Spiral Shocks
R. G. Edgar, J. Nordhaus, E. Blackman +1
As stars evolve along the Asymptotic Giant Branch, strong winds are driven from the outer envelope. These winds form a shell, which may ultimately become a planetary nebula. Many p…
Evidence for Growth of Eccentricity and Mass Clearing in a Disc Interior to a Planet
Richard G. Edgar, Eric Blackman, Alice Quillen +2
We present computational results showing eccentricity growth in the inner portions of a protoplanetary disc. We attribute this to the evolving surface density of the disc. The plan…
The Minimum Gap-opening Planet Mass in an Irradiated Circumstellar Accretion Disk
Richard G. Edgar, Alice C. Quillen, Jaehong Park
We consider the minimum mass planet, as a function of radius, that is capable of opening a gap in an -accretion disk. We estimate that a half Jupiter mass planet can open a gap…
Giant Planet Migration in Viscous Power-Law Discs
R. G. Edgar
Many extra-solar planets discovered over the past decade are gas giants in tight orbits around their host stars. Due to the difficulties of forming these `hot Jupiters' in situ, th…
