Description:
A standard library of theoretical stellar spectra intended for
multiple synthetic photometry applications including spectral
evolutionary synthesis is presented. The grid includes M dwarf model
spectra, hence complementing the first library version established in
Paper I (Lejeune et al., 1997, Cat. J/A+AS/125/229). It covers the
following wide ranges of fundamental parameters:
Teff: 50,000 to 2000K,
logg: 5.5 to -1.02, and
[Fe/H]: +1.0 to -5.0.
A correction procedure is also applied to the theoretical spectra in
order to provide color-calibrated flux distributions over a large
domain of effective temperatures. Empirical Teff-color calibrations
are constructed between 11500K and 2000K, and semi-empirical
calibrations for non-solar abundances ([Fe/H]=-3.5 to +1.0) are
established. Model colors and bolometric corrections for both the
original and the corrected spectra, synthesized in the
UBV(RI)c(JHKLL'M) system, are given for the full range of stellar
parameters.
Synthetic colors:
----------------
Synthetic UBV(RI)c(JHKLM) colors have been computed from both the
original and the corrected model flux distributions presented in
Paper I (1997A&AS..125..229L 1997A&AS..125..229L; see catalog J/A+AS/125/229), as
the files lcb98ori.dat and lcb98cor.dat respectively; the results
are also presented in individual files lcb98xxx.ori and lcb98xxx.cor,
where xxx designates the metallicity (ex: 'm15' --> [Fe/H]=-1.5).
For each file, we give synthetic colors computed from energy-weighted
and photon-weighted stellar fluxes.
Semi-empirical calibrations:
---------------------------
Empirical ([Fe/H]=0.0) and semi-empirical (-3.5≤[Fe/H]≤+1.0)
Teff-colors (UBVRIJHKLM) calibrations are given in Tables 1 to 10.
