We present the results of a large-scale search for new members of the Pleiades star cluster using 2MASS near-infrared photometry and proper motions derived from POSS plates digitized by the USNO PMM program. The search extends to a 10° radius around the cluster, well beyond the presumed tidal radius, to a limiting magnitude of R ∼ 20, corresponding to ∼0.07 M⊙ at the distance and age of the Pleiades. Multiobject spectroscopy for 528 candidates verifies that the search was extremely effective at… 
Brown dwarfs in the Pleiades cluster: Clues to the substellar mass function ,
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 �
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
On the Motion of Stars in the Pleiades According to Gaia DR2 Data
We used GaiaDR2 data on the coordinates, proper motions, and radial velocities of stars in regions with radius d = 2. 5 and size 60 × 60 around the cluster center in order to estimate several
The Stellar mass function of Galactic clusters and its evolution
The stellar mass function of a large sample of Galactic clusters (young and old) can be well reproduced with a tapered power law distribution function with an exponential truncation of the form dN/dM
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
Rotation periods for very low mass stars in the Pleiades
We present the results of a photometric monitoring campaign for very low mass (VLM) members of the Pleiades. Periodic photometric variability was detected for nine VLM stars with masses between 0.08
Binary Formation in the Orion Nebula Cluster: Exploring the Substellar Limit
We present results constraining the multiplicity of the very low mass stars and substellar objects in the Orion Nebula Cluster (ONC). Our sample covers primary masses 0.012–0.1 M ⊙ using archival
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
Near- and Mid-Infrared Photometry of the Pleiades and a New List of Substellar Candidate Members
We make use of new near- and mid-IR photometry of the Pleiades cluster in order to help identify proposed cluster members. We also use the new photometry with previously published photometry to
Long-term Spectroscopic Survey of the Pleiades Cluster: The Binary Population
We present the results of a spectroscopic monitoring program of the Pleiades region aimed at completing the census of spectroscopic binaries in the cluster, extending it to longer periods than


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
A CCD-Based Search for Very Low Mass Members of the Pleiades Cluster
We have obtained deep charge coupled device (CCD)V and I images of a number of fields near the center of the Pleiades open cluster. We have also obtained imaging data for Praesepe, a very similar
Star cluster evolution, dynamical age estimation and the kinematical signature of star formation
We use N-body integration to follow the evolution of clusters of 200 binary systems with different initial half mass radii $R_{0.5}$. We also simulate single-star clusters. All clusters evolve
The search for faint members of the Pleiades. II - Colors, spectral types, and H-alpha emission line strengths for M dwarfs in the Pleiades, Hyades, and Gliese field
Photoelectric and CCD-based BVRI photometry of nearly 100 proper-motion selected Pleiades candidates members extending to V = 18 are presented. A least 75% of these candidates have positions in a V
The Wake of the Pleiades Through the Interstellar Medium in Taurus
A mosaic of IRAS co-added images covering 8°.7×4°.3 reveals a large emission cavity with bright rims that extends some 5° eastward from the Pleiades. This is a novel interstellar structure, unrelated
The Luminosity function and stellar evolution
The evolutionary significance of the observed luminosity function for main-sequence stars in the solar neighborhood is discussed. The hypothesis is made that stars move off the main sequence after
The mass-luminosity relation for stars of mass 1.0 to 0.08 solar mass
Mass-luminosity relations determined at IR wavelengths are presented for stars with masses 1.0 to 0.08 solar mass. Using IR speckle imaging techniques on a sample of nearby binaries, we have been
Statistics of N-body simulations — IV. Unequal masses with a tidal field
We report results of a large number of collisional N-body simulations including a mass spectrum and a tidal field. We emphasize the ways in which evolution differs from that observed in isolated
On the dynamical evolution of the brown dwarf populationin open clusters
It is by now well established that open clusters contain a considerable fraction of brown dwarfs (BDs). This paper investigates the dynamical evolution of this substellar population by using
Statistics of N-body simulations — III. Unequal masses
We describe results from large numbers of $N$-body simulations containing from $250$ to $1000$ stars each. The distribution of stellar masses is a power law, and the systems are isolated. While the
