V1141 Cas UBVRI(RI)c light curves
Listed in IVOA Registry (Virtual Observatory)
High-precision photometric measurements of the unexplored eclipsing star V1141 Cas (P=6.909d, V=12.02mag, e=0.37, Sp=B1 V) have shown that the apsidal rotation velocity, dw/dt=0.127 deg/yr is two times slower than the theoretical value under the synchronism condition, dw/dt=0.235deg/yr.
Description
The physical parameters of the component stars were obtained: T1=23500+/-400K, M1=(8.4+/-0.5)M_{sun}_, R1=(4.24+/-0.08)R_{sun}_, T2=22000+/-400K, M2=(7.0+/-0.5)M_{sun}_, R2=(3.38+/-0.08)R_{sun}_.
The age of the system is determined to be 7.5 mln years for a solar chemical composition. The measured photometric parallax, pi=0.00031"+/-0.00004", is very close to the Gaia value. The interstellar extinction, Av=2.2mag, is 40 percent higher than the survey's data.
