The luminosity function of white dwarfs and M dwarfs, using dark nebulae as opaque outer screens
Leif Festin
By using dark nebulae as opaque outer screens, the luminosity function of white dwarfs and M dwarfs has been studied. High-extinction areas towards the Orion A, Serpens and rho Oph…

Brown Dwarfs in the Pleiades II. A deep optical and near-infrared survey
Leif Festin
The brown dwarf population in the Pleiades cluster has been probed in a deep 850 arcmin2 RIJK survey. The survey is complete to I=21.4 in 76% of the area and to I=20.2 in the remai…

Brown Dwarfs in the Pleiades, a deep IJK survey
L. Festin
An area large enough (180 sq arcmin) to put constraints on a possible low mass brown dwarf population in the Pleiades has been surveyed to very faint magnitudes in I, J and K. The…
