Determination of stellar atmospheric parameters for a sample of the post-AGB stars
We report for the first time the stellar atmospheric parameters for a a set of post-AGB stars classified by Suarez et al. (2006). The stellar spectra were taken from optical region, with low-resolution and have different spectral ranges. We select a sample of 70 objects with A-K spectral types and l...

We report for the first time the stellar atmospheric parameters for a a set of post-AGB stars classified by Suarez et al. (2006).

The large majority of these objects have been scarcely studied and are located toward the galactic south pole region. We employ a set of empirical relationships that use pseudo-equivalent widths like spectral feature to estimate effective temperature, surface gravity and metallicity.
