TL;DR
This study conducted a proper motion survey of the Hyades cluster using UKIDSS and 2MASS data, discovering 12 L dwarf members, many of which are likely binaries, advancing understanding of substellar objects in the cluster.
Contribution
First survey to identify L dwarf members in the Hyades using proper motion data from UKIDSS and 2MASS, revealing new brown dwarf members and their binary nature.
Findings
Discovered 12 L dwarf members in the Hyades.
Identified a high proportion of these L dwarfs as photometric binaries.
Extended the known substellar population of the Hyades cluster.
Abstract
We present the results of a proper motion survey of the Hyades to search for brown dwarfs, based on UKIDSS and 2MASS data. This survey covers ~275 square degrees to depth of K~15 mag, equivalent to a mass of 0.05 solar masses assuming a cluster age of 625 Myr. The discovery of 12 L dwarf Hyades members is reported. These members are also brown dwarfs, with masses between 0.05 < M < 0.075 solar masses. A high proportion of these L dwarfs appear to be photometric binaries.
