A representative sample of Be Stars I: Sample Selection, Spectral Classification and Rotational Velocities

TL;DR

This paper presents a carefully selected sample of 58 Be stars with spectral types O9 to B8.5, providing spectral classifications and rotational velocities to analyze their properties without significant selection bias.

Contribution

It introduces a new, well-defined sample of Be stars with spectral and rotational data, enabling better understanding of their characteristics and distribution.

Findings

Spectral types range from O9 to B8.5.

Rotational velocities are derived for the sample.

No significant selection effects are observed.

Abstract

We present a sample of 58 Be stars containing objects of spectral types O9 to B8.5 and luminosity classes III to V. We have obtained 3670 - 5070 Angstrom spectra of the sample which are used to derive spectral types and rotational velocities. We discuss the distribution of spectral types and rotational velocities obtained and conclude that there are no significant selection effects in our sample.
