Pre-main-sequence isochrones -- III. The Cluster Collaboration isochrone server
Cameron P. M. Bell, Jon M. Rees, Tim Naylor +4
We present an isochrone server for semi-empirical pre-main-sequence model isochrones in the following systems: Johnson-Cousins, Sloan Digital Sky Survey, Two-Micron All-Sky Survey,…
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-…
Can we predict the global magnetic topology of a pre-main sequence star from its position in the Hertzsprung-Russell diagram?
S. G. Gregory, J. -F. Donati, J. Morin +4
ZDI studies have shown that the magnetic fields of T Tauri stars can be significantly more complex than a simple dipole and can vary markedly between sources. We collect and summar…
Pre-main-sequence isochrones -- I. The Pleiades benchmark
Cameron P. M. Bell, Tim Naylor, N. J. Mayne +2
We present a critical assessment of commonly used pre-main-sequence isochrones by comparing their predictions to a set of well-calibrated colour-magnitude diagrams of the Pleiades…
