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…

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
DOI: 10.1016/j.newast.2018.05.003 Bibcode: 2018NewA...65...16B

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…

Star formation toward the H II region IRAS 10427-6032
DOI: 10.1016/j.newast.2018.02.008 Bibcode: 2018NewA...63...27V

The formation and properties of star clusters formed at the edges of the H II regions are poorly known. In this paper, we study stellar content, physical conditions, and star formation processes around a relatively unknown young H II region IRAS 10427-6032, located in the southern outskirts of the Carina Nebula. We study this region by making use …
