New Methods for Determining the Ages of PMS Stars
Tim Naylor, N. J. Mayne, R. D. Jeffries +2
We present three new methods for determining the age of groups of pre-main-sequence stars. The first, creating empirical isochrones allows us to create a robust age ordering, but n…
Fitting the young main-sequence; distances, ages and age spreads
N. J. Mayne, Tim Naylor
We use several main-sequence models to derive distances (and extinctions), with statistically meaningful uncertainties for 11 star-forming-regions and young clusters. The model dep…
Empirical isochrones and relative ages for young stars, and the radiative-convective gap
N. J. Mayne, Tim Naylor, S. P. Littlefair +2
We have selected pre-main-sequence stars in 12 groups of notional ages ranging from 1 Myr to 35 Myrs, using heterogeneous membership criteria. Using these members we have construct…
The Keele-Exeter young cluster survey: I. Low mass pre-main sequence stars in NGC 2169
R. D Jeffries, J. M. Oliveira, Tim Naylor +2
We have used R_C I_C CCD photometry from the Isaac Newton telescope and intermediate resolution spectroscopy from the Gemini North telescope to identify and characterise low-mass (…
