The Rotational Velocity of Helium-rich Pre-White Dwarfs
T. Rauch, S. Koeper, S. Dreizler +3
Previous investigations on hydrogen-rich white dwarfs generally yield only very small rotational velocities (v_rot sin i). We have analyzed line profiles in high-resolution optical…
Astrometry and Photometry for Cool Dwarfs and Brown Dwarfs
C. C. Dahn, H. C. Harris, F. J. Vrba +15
Trigonometric parallax determinations are presented for 28 late type dwarfs and brown dwarfs, including eight M dwarfs with spectral types between M7 and M9.5, 17 L dwarfs with spe…
Meeting the Cool Neighbours, II: Photometry of southern NLTT stars
I. Neill Reid, D. Kilkenny, Kelle L. Cruz
We present BVRI photometry of 180 bright, southern nearby-star candidates. The stars were selected from the New Luyten Two-Tenths proper motion catalogue based on optical/infrared…
Meeting the Cool Neighbours I: Nearby stars in the NLTT Catalogue - Defining the sample
I. Neill Reid, Kelle L. Cruz
We are currently undertaking a program aimed at identifying previously-unrecognised late-type dwarfs within 20 parsecs of the Sun. As a first step, we have cross-referenced Luyten'…
