Broad-band photometric colors and effective temperature calibrations for late-type giants
Broad-band photometric colors and effective temperature calibrations for late-type giants
We present new synthetic broad-band photometric colors for late-type giants based on synthetic spectra calculated with the PHOENIX model atmosphere code. The grid covers effective temperatures K, gravities , and metallicities . We show that individual broad-band photometric colors are strongly affected by model parameters such as molecular opacities, gravity, …
