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 10i radius around the cluster, well beyond the presumed tidal radius, to a limiting magnitude of R D 20, corresponding to D0.07 at the distance and age of the M _ Pleiades. Multiobject spectroscopy for 528 candidates veri—es that the search was extremely eUective at… Expand
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 �Expand
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 withExpand
The Distribution of Stellar Mass in the Pleiades
As part of an effort to understand the origin of open clusters, we present a statistical analysis of the currently observed Pleiades. Starting with a photometric catalog of the cluster, we employ aExpand
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 severalExpand
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 currentExpand
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 toExpand

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/dMExpand
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 0.08Expand
