New observations of chemically peculiar stars with ESPaDOnS

TL;DR

This paper reports initial spectropolarimetric observations of chemically peculiar stars, estimating their physical parameters and chemical abundances, and investigates potential vertical stratification of elements in their atmospheres.

Contribution

It provides new spectroscopic data and analysis of poorly studied chemically peculiar stars using ESPaDOnS, including measurements of their physical and chemical properties.

Findings

Determined radial velocities and rotational velocities of the stars.

Estimated chemical abundances of various elements.

Explored possible vertical stratification of iron and chromium.

Abstract

We present the first results of the estimation of gravity and effective temperature for some poorly studied chemically peculiar stars that were recently observed with the spectropolarimeter ESPaDOnS at CFHT. We have analyzed the spectra of HD71030, HD95608 and HD116235 to determine their radial velocity, Vsin(i) and the average abundance of several chemical species. We have also analyzed our results to verify for possible vertical abundance stratification of iron and chromium in these stars.
