Low mass stars, brown dwarf candidates and the mass function of the young open cluster NGC 2547
R. D. Jeffries, Tim Naylor, C. R. Devey +1
We present a catalogue of RIZ photometry over an area of 0.855 square degrees, centred on NGC 2547. The survey is substantially complete to limits of R_c=21.5, I_c=19.5, Z=19.5. We…
Mass segregation in the young open cluster NGC 2547
S. P. Littlefair, Tim Naylor, R. D. Jeffries +2
We present a study of mass segregation of the young (20-35 Myr isochronal age), open cluster NGC 2547. We find good evidence that mass segregation exists in NGC 2547 down to 3 Msun…
The lithium depletion boundary and the age of NGC 2547
J. M. Oliveira, R. D. Jeffries, C. R. Devey +4
We present the results of a photometric and spectroscopic survey of cool M dwarf candidates in the young open cluster NGC 2547. Using the 2dF fiber spectrograph, we have searched f…
Optimal photometry for colour-magnitude diagrams and its application to NGC 2547
Tim Naylor, E. J. Totten, R. D. Jeffries +3
We have developed the techniques required to use the optimal photometry algorithm of Naylor (1998) to create colour-magnitude diagrams with well defined completeness functions. To…
