Key Points

To determine the orbit and mass of the binary system HIP 10944 using speckle interferometry.
Monitored the binary system HIP 10944 with speckle interferometry from 2007 to 2025
Utilized the 6-m telescope of the Special Astrophysical Observatory
Constructed the orbit based on positional parameters measured during monitoring.
Discovered the binary system HIP 10944 within the Cas–Tau OB association
Determined the orbital period to be 20.90 years
Calculated the sum of the masses of the system’s components as 4.26 ± 0.06 solar masses.

Abstract

Massive stars that form the Gould Belt OB associations are known to have higher multiplicity than solar-type stars. Due to their luminosity and close vicinity, they are optimal targets for speckle interferometry. Among the members of the Cas–Tau OB association, observed with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (BTA SAO RAS), a binary system, HI P10944 (B9VpSi, G=5m. 53), was discovered for the first time. We present the results of speckle interferometry monitoring of the star from 2007 to 2025, covering almost the entire orbital period (P₎ₑ₁=20. 90 yrs). Based on the measured positional parameters, an orbit was constructed and the sum of the masses of the system’s components was determined (M*=4. 26 0. 06M_).
