On discovery of strong magnetic field in the binary system HD34736

Romanyuk, I. I.; Semenko, E. A.; Yakunin, I. A. +1 more

We present the results of a study of the star HD34736. The spectropolarimetric observations carried out at the 6-m telescope showed the presence of a strong variable longitudinal magnetic field, exceeding ‑4500 G. The analysis of the Hipparcos photometry gives a set of possible periods of the brightness variability of the star, of which

The speckle interferometric binary system Gl 150.2 (HIP17491) is analyzed using atmosphere modeling and dynamical analysis simultaneously. A synthetic spectral energy distribution (SED) for each of the two components of the system is built using Kurucz blanketed models. These SEDs are combined together to form the total flux, which is compared wit…
