Empirical calibration of the near-IR Ca II triplet - III. Fitting functions
A. J. Cenarro, J. Gorgas, N. Cardiel +2
Using a near-IR stellar library of 706 stars with a wide coverage of atmospheric parameters, we study the behaviour of the Ca II triplet strength in terms of effective temperature,…
Empirical calibration of the near-IR Ca II triplet - II. The stellar atmospheric parameters
A. J. Cenarro, J. Gorgas, N. Cardiel +3
We present an homogeneous set of stellar atmospheric parameters (Teff, log g, [Fe/H]) for a sample of about 700 field and cluster stars which constitute a new stellar library in th…
Empirical calibration of the near-IR Ca II triplet - I. The stellar library and index definition
A. J. Cenarro, N. Cardiel, J. Gorgas +3
A new stellar library at the near-IR spectral region developed for the empirical calibration of the Ca II triplet and stellar population synthesis modeling is presented. The librar…
