We have derived the abundances of 36 chemical elements in one Cepheid star , ASAS 181024–2049.6 , located R _ { G } = 2.53 kpc from the Galactic center .
This star falls within a region of the inner thin disc poorly sampled in Cepheids .
Our spectral analysis shows that iron , magnesium , silicon , calcium and titanium LTE abundances in that star support the presence of a plateau-like abundance distribution in the thin disc within 5 kpc of the Galactic center , as previously suggested by ( 18 ) .
If confirmed , the flattening of the abundance gradient within that region could be the result of a decrease in the star formation rate due to dynamic effects , possibly from the central Galactic bar .
