AN APPROACH TO EFFECTIVE TEMPERATURE AND SURFACE GRAVITY IN POST-AGB AND RV TAURI STARS IN THE NEAR-IR REGION
A number of empirical correlations that allow us to calculate the effective temperature and surface gravity for a set of evolved post-AGB and RV Tauri stars are determined using as calibrators the intrinsic colors of 2MASS (Two Micron All Sky Survey) photometry. We have analyzed a total sample of 36...
