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…
Can variability account for apparent age spreads in OB association colour-magnitude diagrams?
Ben Burningham, Tim Naylor, S. P. Littlefair +1
We have investigated the role of photometric variability in causing the apparent age spreads observed in the colour-magnitude diagrams of OB associations. We have found that the co…
The Star Formation Rate of the Universe at z~6 from the Hubble Ultra Deep Field
A. J. Bunker, E. R. Stanway, R. S. Ellis +1
We determine the abundance of i'-band drop-outs in the recently-released HST/ACS Hubble Ultra Deep Field (UDF). Since the majority of these sources are likely to be z~6 galaxies wh…
