Evolutionary stage of the spectral variable BD+48 1220=IRAS 05040+4820
V. G. Klochkova, E. L. Chentsov, N. S. Tavolzhanskaya +1
Based on high-resolution observations (R=60000 and 75000), we have studied the optical spectral variability of the star BD+48 1220 (IRAS05040+4820). We have measured the equivalent…
