Constraining the Star Formation Histories of Spiral Bulges
R. N. Proctor, A. E. Sansom
Long-slit spectroscopic observations of line-strengths and kinematics made along the minor axes of four spiral bulges are reported. Comparisons are made between central line-streng…
The distance to NGC 6397 by M-subdwarf main-sequence fitting
I. Neill Reid, John E. Gizis
Recent years have seen a substantial improvement both in photometry of low luminosity stars in globular clusters and in modelling the stellar atmospheres of late-type dwarfs. We bu…
High-resolution Spectra of Very Low-Mass Stars
C. G. Tinney, I. N. Reid
We present the results of high-resolution (1-0.4A) optical spectroscopy of a sample of very low-mass stars. These data are used to examine the kinematics of the stars at the bottom…
Younger and brighter - New distances to globular clusters based on Hipparcos parallax measurements of local subdwarfs
I. Neill Reid
We have used new parallax measurements, obtained by the Hipparcos satellite, of fifteen nearby, metal-poor stars to re-define the subdwarf main-sequence. All of these stars have pa…
