- Title
A photometric comparison between the Hyades main sequence and a spectroscopically-chosen sample of field dwarfs.

Smith, Graeme H.
- Abstract
A sample of field dwarfs with spectroscopic metallicities derived on a uniform abundance scale by Valenti & Fischer is compared with Hyades main sequence stars in various photometric diagrams. Field dwarfs with metallicities 0:14 ≤ [Fe=H] ≤ 0:29 are found to match the Hyades (m1, b - y) locus very well. In both the (Mv, B-V) colour-magnitude diagram and the (c1, b - y) diagram the Hyades main sequence is found to form a lower envelope to the field dwarfs of this metallicity range. There is no evidence in the comparisons made for the so-called Hyades anomaly.
