Abstract:
Ten spectrograms of T Vul at a dispersion of 8.47Å mm-¹ have been used for an analysis of the parameters of stellar atmosphere during its pulsation cycle. A differential curve of growth method relative to the Sun has been used to evaluate atmospheric parameters. The range in ɵexc is from 0.88 to 1.00. Mean abundances for twenty elements have been estimated relative to [N fe]. A deficiency by a factor of 2.4 has been found in S-process elements with respect to those formed by the e-process.
