Announcing chemical analysis of three singular stars

Many interesting analyzes involving three singular stars HD 51959, HD 88035 and HD 121447 have been published by scientists. Research, based on spectral data obtained by extended spectrophotometer (FEROS).

The researchers conducted an analysis of the chemical abundance of the three singular stars, HD 51959, HD 88035 and HD 121447.

Karinkuzhi's team obtained the high resolution spectrum of these three stars by using the FEROS spectroscopy instrument installed on the ESO telescope 1.52 m in Chile. This tool allows researchers to analyze the abundance of more than 20 chemical elements in these stars.

The author wrote in the report: "The percentage of heavy elements observed in the three stars is consistent with most barium stars in the universe."

According to the study, HD 51959 appears to be a light barium star, HD 88035 a strong barium star and HD 121447 barium metal star poor. The barium ratio for iron [Ba / Fe] in HD 51959, HD 88035 and HD 121447 respectively 0.81, 1.51 and 2.67.

The researchers found that the abundance of carbon in HD 121447 was enhanced. When it comes to the abundance of nitrogen, the results show that nitrogen is enhanced in all three stars.

Furthermore, the proportion of alpha-factor residues of stars studied, except magnesium, is generally consistent with barium stars. Moreover, the abundance of iron elements in HD 51959 and HD 88035 is typical for the giant stars of the barium star strain.
