Gas Evolution in Protoplanetary Disks
Peter Woitke, Bill Dent, Wing-Fai Thi +9
This article summarizes a Splinter Session at the Cool Stars XV conference in St. Andrews with 3 review and 4 contributed talks. The speakers have discussed various approaches to u…
From discs to planetesimals I: evolution of gas and dust discs
Richard Alexander
I review the processes that shape the evolution of protoplanetary discs around young, solar-mass stars. I first discuss observations of protoplanetary discs, and note in particular…
The Monitor project: JW 380 -- a 0.26, 0.15 Msol pre main sequence eclipsing binary in the Orion Nebula Cluster
Jonathan Irwin, Suzanne Aigrain, Simon Hodgkin +14
We report the discovery of a low-mass (0.26 +/- 0.02, 0.15 +/- 0.01 Msol) pre-main-sequence eclipsing binary with a 5.3 day orbital period. JW 380 was detected as part of a high-ca…
Photoevaporation of protoplanetary discs II: evolutionary models and observable properties
R. D. Alexander, C. J. Clarke, J. E. Pringle
We present a new model for protoplanetary disc evolution. This model combines viscous evolution with photoevaporation of the disc, in a manner similar to Clarke, Gendrin & Sotomayo…
Photoevaporation of protoplanetary discs I: hydrodynamic models
R. D. Alexander, C. J. Clarke, J. E. Pringle
In this paper we consider the effect of the direct ionizing stellar radiation field on the evolution of protoplanetary discs subject to photoevaporative winds. We suggest that mode…
The stellar mass-accretion rate relation in T Tauri stars and brown dwarfs
R. D. Alexander, P. J. Armitage
Recent observations show a strong correlation between stellar mass and accretion rate in young stellar and sub-stellar objects, with the scaling holdi…
