Meeting the Cool Neighbors VIII: A preliminary 20-parsec census from the NLTT catalogue
I. N. Reid, K. L. Cruz, P. R. Allen +8
Continuing our census of late-type dwarfs in the Solar Neighbourhood, we present BVRI photometry and optical spectroscopy of 800 mid-type M dwarfs drawn from the NLTT proper motion…
Element abundances in cool white dwarfs. II. Ultraviolet observations of DZ white dwarfs
B. Wolff, D. Koester, J. Liebert
We present a small data base of homogeneously derived photospheric element abundances of DZ white dwarfs and related objects. Our previous investigations are supplemented with the…
Substellar Companions to Main Sequence Stars: No Brown Dwarf Desert at Wide Separations
John E. Gizis, J. Davy Kirkpatrick, Adam Burgasser +4
We use three field L and T dwarfs which were discovered to be wide companions to known stars by the Two Micron All-Sky Survey (2MASS) to derive a preliminary brown dwarf companion…
Discovery of a Magnetic DZ White Dwarf with Zeeman-Split Lines of Heavy Elements
I. Neill Reid, James Liebert, Gary D. Schmidt
A spectroscopic survey of previously-unstudied Luyten Half Second proper motion stars has resulted in the discoveries of two new cool magnetic white dwarfs. One (LHS 2273) is a rou…
Detection of H Alpha Emission in a Methane (T-Type) Brown Dwarf
Adam J. Burgasser, J. Davy Kirkpatrick, I. Neill Reid +3
We report the detection of H{} emission in the T dwarf (methane brown dwarf) 2MASSW J1237392+652615 over three days using the Keck Low Resolution Imaging Spectrograph. The measu…
Discovery of a Brown Dwarf Companion to Gliese 570ABC: A 2MASS T Dwarf Significantly Cooler than Gliese 229B
A. J. Burgasser, J. D. Kirkpatrick, R. M. Cutri +10
We report the discovery of a widely separated (258$\farcs3\pm0\farcs$4) T dwarf companion to the Gl 570ABC system. This new component, Gl 570D, was initially identified from the Tw…
