A search for peculiar stars in the open cluster Hogg 16

Paunzen, Ernst; Netopil, Martin; Cariddi, Stefano +5 more

The study of chemically peculiar (CP) stars in open clusters provides valuable information about their evolutionary status. Their detection can be performed using the Δa photometric system, which maps a characteristic flux depression at λ ∼ 5200 Å. This paper aims at studying the occurrence of CP stars in the earliest stages of evolution of a stel…

Star formation history: Modeling of visual binaries

Tutukov, A. V.; Kovaleva, D. A.; Malkov, O. Yu. +3 more

Most stars form in binary or multiple systems. Their evolution is defined by masses of components, orbital separation and eccentricity. In order to understand star formation and evolutionary processes, it is vital to find distributions of physical parameters of binaries.

We have carried out Monte Carlo simulations in which we simulate differe…

V1719 Aql: A solar-type twin binary

Bakış, Volkan; Yücel, Gökhan; Bakış, Hicran

Stellar parameters of the solar type twin binary V1719 Aql have been derived with relatively high accuracy. The erroneous known orbital period was corrected. The true period of the system (P = 4.35 days) is twice the value known in the literature. The system is located at 77 ± 3 pc from the Sun, which matches, within the uncertainty box, the dista…
