Catalog Service: The spectrum of FG Sge in 1992
Description
Wavelength measurements and line identifications from the 0.14A/pixel echelle spectra of FG Sge secured two weeks before the drastic dimming of the star in 1992 are presented. The abundances of 18 elements are derived. These abundances have not changed from 1986. The main features of the chemical composition of FG Sge atmosphere are the depletion of iron-group elements and the marked overabundances (up to 3 dex) of s-process elements. First time in the observational history of FG Sge C_2_ Swan bands are identified in its spectrum.
