- Аннотация: The results of new spectral and photometric observations of the poorly studied S-star CSS 1102 are presented. According to the analysis of spectra, CSS 1102 was classified as a symbiotic star. We observed HI, HeI and [NeIII] emission lines in both spectra of the star. The absorption spectrum demonstrates the prominent molecular bands of TiO, ZrO and YO. The system consists of a cold component that is a zirconium star of spectral type S4.5/2, a hot component with 40000 K < Thot < 55000 K, and a nebula. Photometric monitorings in the B band showed the existence of a flickering effect with different periods in CSS 1102. This variability may be associated with emission of an accretion disk in CSS 1102system.
