Abstract:
In an effort to extend the still limited sample of s-process enriched
post-AGB stars, high-resolution, high signal-to-noise VLT+UVES spectra
of the optical counterparts of the infrared sources IRAS 06530-0213
and IRAS 08143-4406 were analysed.
Description:

stars IRAS 06530-0213 and IRAS 08143-4406 based on UVES spectra

setting of IRAS 08143-4406

Note (1): the atomic identification is the two-digit designation to the
left of the decimal point, the single digit to the right of the
decimal point represents the ionisation stage (e.g. 26.1 is FeII)
Note (2): the UVES instrument can operate with the blue and the red arm
simultaneously; in this dichroic mode, the blue setting was centered
on 437nm and the red one on 860nm. There is a time gap of 16 days
between the RED580 and DI2 observation of IRAS 08143-4406
