Chemical composition of post-AGB star candidates
R. E. Molina, C. B. Pereira, A. Arellano Ferro
We present a high resolution detailed abundance analysis for a sample of six post-AGB candidate stars, five of them had not been studied spectroscopically in the optical region. Al…
Determination of stellar atmospheric parameters for a sample of the post-AGB stars
R. E. Molina
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…
Chemical abundances for A-and F-type supergiant stars
R. E. Molina, H. Rivera
We present the stellar parameters and elemental abundances of a set of A--F-type supergiant stars HD\,45674, HD\,180028, HD\,194951 and HD\,224893 using high resolution (\,$\sim…
Spectroscopic analysis of four post-AGB candidates
R. E. Molina, S. Giridhar, C. B. Pereira +2
We have done a detailed abundance analysis of four unexplored candidate post- Asymptotic Giant Branch(AGB) stars IRAS 13110 - 6629, IRAS 17579 - 3121, IRAS 18321 - 1401 and IRAS 18…
Detailed atmospheric abundance analysis of the optical counterpart of the IR source IRAS 16559-2957
R. E. Molina, A. Arellano Ferro
We have undertaken a detailed abundance analysis of the optical counterpart of the IR source IRAS16559-2957 with the aim of confirming its possible post-AGB nature. The star shows…
An approach to effective temperature and surface gravity in post-AGB and RV Tauri stars at the near-IR region
R. E. Molina
A number of empirical correlations that allows us to calculate the effective temperature and surface gravity for a set evolved post-AGB and RV Tauri stars are determined using as c…
