O článku:
In this contribution, we explore the orbital variability of the Hα-line emission and absorption components of the symbiotic system EG And.We have found that the equivalent width of the core emission is the largest at the orbital phase φ ≈ 0.4 and the smallest at φ ≈ 0.2. This probably reflects an asymmetric distribution of the cool giant wind at the orbital-plane area. Furthermore, the core emission equivalent width has a secondary maximum at φ ≈ 0.1. The strongest absorption in the profile is measured around the inferior conjunction of the white dwarf, φ &approx 0.4. This suggests that the ionized region is partially optically thick in the Hα line.
