Abstract:
We present empirical metallicity-dependent calibrations of effective
temperature against colours for dwarfs of luminosity classes IV and V
and for giants of luminosity classes II and III, based on a collection
from the literature of about two hundred nearby stars with direct
effective temperature measurements of better than 2.5 per cent. The
calibrations are valid for an effective temperature range 3100-10000K
for dwarfs of spectral types M5 to A0 and 3100-5700K for giants of
spectral types K5 to G5. A total of 21 colours for dwarfs and 18
colours for giants of bands of four photometric systems, i.e. the
Johnson (UBVRJIJJHK), the Cousins (RCIC), the Sloan Digital
Sky Survey (gr) and the Two Micron All Sky Survey (JHKs), have been
calibrated. Restricted by the metallicity range of the current sample,
the calibrations are mainly applicable for disc stars ([Fe/H]≳-1.0).
The normalized percentage residuals of the calibrations are typically
2.0 and 1.5 per cent for dwarfs and giants, respectively. Some
systematic discrepancies at various levels are found between the
current scales and those available in the literature (e.g. those based
on the infrared flux method or spectroscopy). Based on the current
calibrations, we have re-determined the colours of the Sun. We have
also investigated the systematic errors in effective temperatures
yielded by the current on-going large-scale low- to
intermediate-resolution stellar spectroscopic surveys. We show that
the calibration of colour (g-Ks) presented in this work provides an
invaluable tool for the estimation of stellar effective temperature
for those on-going or upcoming surveys.
Description:
Based on nearly two hundred dwarf (luminosity classes: IV/V) and giant
(luminosity classes: II/III) stars with direct effective temperature
measurements of better than 2.5 per cent collected from the
literature, we have derived metallicity-dependent Teff-colour
relations in twenty-one colours for dwarfs and eighteen colours for
giants in four photometric systems (the Johnson, Cousins, SDSS and
2MASS). The compiled data of dwarf and giant sample stars employed in
the current work is presented.
