Proper motions of field L and T dwarfs -II (2008)
Casewell, S. L., Jameson, R. F., Burleigh, M. R.
By using images taken with WFCAM on UKIRT and SofI on the NTT and combining them with 2MASS we have measured proper motions for 126 L and T dwarfs in the dwarf archive. Two of these L dwarfs appear...
Burleigh, M. R., Clarke, F. J., Hogan, E., Brinkworth, C. S., Bergeron, P., Dufour, P., ...
We report limits in the planetary-mass regime for companions around the nearest single white dwarf to the Sun, van Maanen's star (vMa2), from deep J-band imaging with Gemini North and Spitzer...
Farihi, J., Burleigh, M. R., Hoard, D. W.
The nature of the excess near-infrared emission associated with the magnetic white dwarf commonly known as SDSS 1212 is investigated primarily through spectroscopy, and also via photometry. The...

The close DAO+dM binary RE (2007)
Gamma Stratified, M. R. Burleigh, M. A. Barstow, P. D. Dobbie
. We have analysed the EUVE spectrum of the DAO white dwarf RE J0720\Gamma318. In contrast to the optical spectrum, which can only be fitted with a homogeneously mixed H+He atmosphere, we find the...
Is 2RE J0357+283 the most coronally active star in the Galaxy? (2007)
Jeffries Burleigh, R. D. Jeffries, M. R. Burleigh, R. M. Robb
. The late-type stellar counterpart to the EUV source 2RE J0357+283 is found to be an ultra-fast rotating K2V star, with a rotation period of 8.76 hrs and v sin i of 141\Sigma5 km s \Gamma1 . If this...
