Analyses of Archival Data for Cool Dwarfs. VI. The 1993 Versions of the Temperature and [Fe/H] Catalogs

Abstract

ABSTRACT. This paper contains supplements to two catalogs which have previously been published by the author. One of the supplements updates a catalog of temperatures for FGK dwarfs (see Taylor, PASP, 106, 452, 1994 which require comment, discussions of issues such as data editing and zero-point corrections are given. A review is also given of a problem described by Gray (PASP, 106, 1248(PASP, 106, , 1994, who finds that his spectroscopic temperatures and photometric temperatures from Paper II scatter more around their mean relation than one would expect from the contributing rms errors. It is found that near-Sun reddening (which is Gray's preferred solution of the problem) is not a defensible explanation for this scatter. For the moment, the real source of the scatter remains unknown.

High resolution spectroscopy over $\mathsf{\lambda\lambda}$ 8500-8750 Å for GAIA

“…Straight mean values have no direct meaning because of the lack of homogeneity of the sources. We thus preferred Taylor (1995Taylor ( , 1999 weighted means, which were obtained after a shift to a common zero point, but adopted Cayrel de Strobel et al (1997 Fig. 1.…”

Library of high and mid-resolution spectra in the Ca ii H & K, H∝, , Hβ, Na i D1, D2, and He i D3 line regions of F, G, K and M field stars

“…Hence, they have not been used as reference stars. Taylor 1994Taylor , 1995, rotational period (P rot ) and v sini (from Donahue 1993;Baliunas et al 1995). The T sp given between brackets are from Hoffleit & Warren (1991) and the values of v sini marked with "*" are from the references given in .…”

Two nearby M dwarf binaries from the Two Micron All Sky Survey

“…The Hipparcos parallax places it at 14.9 parsec (Perryman et al 1997). Taylor’s (1995) analysis of all metallicity determinations of the star indicates that [Fe/H]=+0.170±0.052. Using the Hipparcos distance and the photometry of Edvardsson et al (1993); Ng & Bertelli (1998) find M =1.02 M ⊙ and log(age)=9.854±0.083.…”
