The UM, a fully--compressible, non--hydrostatic, deep atmosphere GCM, applied to hot Jupiters
N. J. Mayne, I. Baraffe, David M. Acreman +6
We are adapting the Global Circulation Model (GCM) of the UK Met Office, the so--called Unified Model (UM), for the study of hot Jupiters. In this work we demonstrate the successfu…
Using the UM dynamical cores to reproduce idealised 3D flows
N. J. Mayne, I. Baraffe, David M. Acreman +5
We demonstrate that both the current (New Dynamics), and next generation (ENDGame) dynamical cores of the UK Met Office global circulation model, the UM, reproduce consistently, th…
Can we predict the magnetic properties of PMS stars from their H-R diagram location?
S. G. Gregory, J. -F. Donati, J. Morin +4
Spectropolarimetric observations combined with tomographic imaging techniques have revealed that all pre-main sequence (PMS) stars host multipolar magnetic fields, ranging from str…
A lithium depletion boundary age of 22 Myr for NGC 1960
R. D. Jeffries, Tim Naylor, N. J. Mayne +2
We present a deep Cousins RI photometric survey of the open cluster NGC 1960, complete to R_C \simeq 22, I_C \simeq 21, that is used to select a sample of very low-mass cluster can…
Pre-main-sequence isochrones -- II. Revising star and planet formation timescales
Cameron P. M. Bell, Tim Naylor, N. J. Mayne +2
We have derived ages for 13 young (<30 Myr) star-forming regions and find they are up to a factor two older than the ages typically adopted in the literature. This result has wide-…
No evidence for intense, cold accretion onto YSOs from measurements of Li in T-Tauri stars
Darryl J. Sergison, N. J. Mayne, Tim Naylor +2
We have used medium resolution spectra to search for evidence that proto-stellar objects accrete at high rates during their early 'assembly phase'. Models predict that depleted lit…
