We have obtained a new, deep, wide-field optical imaging survey of the young Alpha Persei cluster which reveals a well-populated lower main sequence extending...

We have discovered a relatively large number of brown dwarf candidates in the Pleiades young open cluster as a result of a deep CCD IZ survey covering 1 deg^2...

In this invited talk, I briefly summarise early photometric and proper motion surveys carried out in the nearest and youngest open clusters to introduce the...

Two new late-type L subdwarfs were discovered in our recent search of UKIDSS and SDSS. We discuss the signatures of halo brown dwarfs based on known and new L...

Brown dwarfs are objects with masses, effective temperatures and luminosities intermediate between those of very low-mass stars and the most massive giant...
