We present the results of a 6.4 square degrees imaging survey of the Pleiades cluster in the I and Z-bands. The survey extends up to 3 degrees from the cluster center and is 90% complete down to I � 22. It covers a mass range from 0.03 Mto 0.48 Mand yields 40 brown dwarf candidates (BDCs) of which 29 are new. The spatial distribution of BDCs is fitted by a King profile in order to estimate the cluster substellar core radius. The Pleiades mass function is then derived accross the stellar… 
Proper motion Pleiades candidate L-type brown dwarfs
We present results of an optical and near-infrared (IR) 1.8 deg^2 survey in the Pleiades open cluster to search for substellar objects. From optical I-band images from the CFHT and J-band images from
Brown dwarfs and very low mass stars in the Hyades cluster : a dynamically evolved mass function
Aims. We conducted a search for brown dwarfs (BDs) and very low mass (VLM) stars in the 625 Myr-old Hyades cluster in order to derive the cluster's mass function across the stellar-substellar
Exploring the lower mass function in the young open cluster ic 4665
We present a study of the young (30-100 Myr) open cluster IC 4665 with the aim to determine the shape of the mass function well into the brown dwarf regime. We photometrically select 691 low-mass
The Substellar Population of the Young Cluster λ Orionis
By collecting optical and infrared photometry and low-resolution spectroscopy, we have identified a large number of low-mass stars and brown dwarf candidates belonging to the young cluster (∼5 Myr)
The lower mass function of the young open cluster Blanco 1: from 30 M_(Jup) to 3 M_☉
Aims. We performed a deep wide field optical survey of the young (~100−150 Myr) open cluster Blanco 1 to study its low mass population well down into the brown dwarf regime and estimate its mass
A photometric and astrometric investigation of the brown dwarfs in Blanco 1
We present the results of a photometric and astrometric study of the low-mass stellar and substellar population of the young open cluster Blanco 1. We have exploited J -band data, obtained recently
The mass function of IC 4665 revisited by the UKIDSS Galactic Clusters Survey
Context. Knowledge of the mass function in open clusters constitutes one way to constrain the formation of low-mass stars and brown dwarfs as does the knowledge of the frequency of multiple systems
A Deep Infrared Photometric Survey for Very Low Mass Brown Dwarfs in the Pleiades
This paper presents the results of a deep infrared survey for low-mass brown dwarfs in the Pleiades cluster. By comparing J-band (1.25 μm) and I-band (0.83 μm) photometry of an ∼450 arcmin2 area with
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey – I. The Pleiades★
Over the past decades open clusters have been the subject of many studies. Such studies are crucial considering that the universality of the initial mass function is still a subject of current
Brown Dwarfs in Young Open Clusters
We report new estimate for the lower Pleiades mass function across the stellar/substellar boundary. We find that it is well represented by a single power-law dn/dm α m −0.60±0.11 between 0.03M⊙ and


Brown dwarfs in the pleiades: spatial distribution and mass function
Using new infrared data we have reassessed the membership status of candidate low-mass Pleiads unearthed by the International Telescope Project IZ survey. Those with I–K colours consistent with

We combine results from imaging searches for substellar objects in the σ Orionis cluster and follow-up photometric and spectroscopic observations to derive a census of the brown dwarf population in a
New Brown Dwarfs in the Pleiades Cluster
We present intermediate- and low-resolution optical spectroscopy (650-915 nm) of seven faint, very red objects (20>I≥17.8, I-Z≥ 0.5) discovered in a CCD-based IZ survey covering an area of 1 deg2 in

The mass of the Pleiades
A membership catalogue for the Pleiades is divided into four mass bins, and a tidally truncated King profile is fitted to each bin with good agreement with the data. The tidal radius of the cluster
