The origin and evolution of transition discs: successes, problems and open questions
James E. Owen
Transition discs are protoplanetary discs that show evidence for large holes or wide gaps (with widths comparable to their radii) in their dust component. These discs could be givi…
Hot Jupiter Breezes: Time-dependent Outflows from Extrasolar Planets
James E. Owen, Fred C. Adams
We explore the dynamics of magnetically controlled outflows from Hot Jupiters, where these flows are driven by UV heating from the central star. In these systems, some of the open…
The initial physical conditions of Kepler-36 b & c
James E. Owen, Timothy D. Morton
The Kepler planetary system consists of two exoplanets at similar separations (0.115 & 0.128 AU), which have dramatically different densities. The inner planet has a density consis…
Minimalist coupled evolution model for stellar x-ray activity, rotation, mass loss, and magnetic field
Eric G. Blackman, James E. Owen
Late-type main sequence stars exhibit an x-ray to bolometric flux ratio that depends on , the ratio of rotation period to convective turnover time, as ${\tilde Ro}^{-ζ…
The long-term evolution of photoevaporating transition discs with giant planets
Giovanni P. Rosotti, Barbara Ercolano, James E. Owen
Photo-evaporation and planet formation have both been proposed as mechanisms responsible for the creation of a transition disc. We have studied their combined effect through a suit…
Far-infrared signatures and inner hole sizes of protoplanetary discs undergoing inside-out dust dispersal
Barbara Ercolano, Christine Koepferl, James Owen +1
By means of radiative transfer simulation we study the evolution of the far-infrared colours of protoplanetary discs undergoing inside-out dispersal, often referred to as transitio…
