A search for previously unrecognised metal-poor subdwarfs in the Hipparcos astrometric catalogue

I. Neill Reid, F. van Wyk, F. Marang +3

We have identified 317 stars included in the Hipparcos astrometric catalogue which have parallaxes measured to a precision of better than 15%, and whose location in the (M_V, (B-V)…

Near-Infrared Spectral Classification of late-M and L Dwarfs

I. Neill Reid, A. J. Burgasser, K. L. Cruz +2

We present near-infrared (1 to 2.5 micron) low-resolution spectroscopy of eleven ultracool dwarfs with spectral types ranging from M7 to L8. Combining our observations with data pu…

Beyond M: Ultracool dwarfs in the Solar Neighbourhood

I. Neill Reid

I review the optical and near-infrared spectral characteristics of the extremely cool dwarfs grouped under the new classification of type L. These include both very low-mass stars…

Low-mass spectroscopic binaries in the Hyades: a candidate brown dwarf companion

I. N. Reid, S. Mahoney

We have used the HIRES echelle spectrograph in the Keck I telescope to obtain high-resolution spectroscopy of 51 late-type M dwarfs in the Hyades cluster. Cross-correlating the cal…

New Neighbors from 2MASS: Activity and Kinematics at the Bottom of the Main Sequence

John E. Gizis, David G. Monet, I. Neill Reid +3

We have combined 2MASS and POSS II data in a search for nearby ultracool (later than M6.5) dwarfs with K_s<12. Spectroscopic follow-up observations identify 53 M7 to M9.5 dwarfs an…

HST Observations of M Subdwarfs

John E. Gizis, I. Neill Reid

We present the results of an HST snapshot program to search for very-low-mass stellar companions to nearby M subdwarfs. None of our nine targetted metal-poor primaries have compani…
