- Abstract
- High-precision photometric measurements of the unexplored eclipsing star V1141 Cas (P = 6.909, V = 12.02, e = 0.37, Sp B1 V) have shown that the apsidal rotation velocity, ω = 0.127°/yr, is two times slower than the theoretical value under the synchronism condition, ω = 0.235°/yr. The physical parameters of the component stars were obtained: T = 23500 ± 400 K, M = 8.4 ± 0.5 M, R = 4.24 ± 0.08 R, T = 22000 ± 400 K, M = 7.0 ± 0.5 M, R = 3.38 ± 0.08 R. The age of the system is determined to be 7.5 min years with a solar chemical composition. The measured photometric parallax, π = 0.00031″ ± 0.00004″, is very close to the Gaia value. The interstellar extinction, A = 2.2, is 40 percent higher than the survey's data.
