The evolution of circumstellar discs in the Galactic Centre: an application to the G-clouds
James E. Owen, Douglas N. C. Lin
The Galactic Centre is known to have undergone a recent star formation episode a few Myrs ago, which likely produced many T Tauri stars hosting circumstellar discs. It has been sug…
Formation of Orion Fingers
Ross Dempsey, Nadia L. Zakamska, James E. Owen
"Orion fingers" are a system of dozens of bowshocks, with the wings of shocks pointing to a common system of origin, which is centered on a dynamically disintegrating system of sev…
On the lifetime of discs around late type stars
Barbara Ercolano, Nate Bastian, Loredana Spezzi +1
We address the question of whether protoplanetary discs around low mass stars (e.g. M-dwarfs) may be longer lived than their solar-type counterparts. This question is particularly…
The JCMT Legacy Survey of the Gould Belt: a first look at Serpens with HARP
S. F. Graves, J. S. Richer, J. V. Buckle +32
The Gould Belt Legacy Survey (GBS) on the JCMT has observed a region of 260 square arcminutes in 12CO J=3--2 emission, and a 190 square arcminute subset of this in 13CO and C18O to…
Theoretical spectra of photoevaporating protoplanetary discs: An atlas of atomic and low-ionisation emission lines
Barbara Ercolano, James E. Owen
We present a calculation of the atomic and low-ionisation emission line spectra of photoevaporating protoplanetary discs. Line luminosities and profiles are obtained from detailed…
