Be Stars as Seen Through Telescopes in Survey Mode (II)

TL;DR

This paper reviews survey-based studies of Be stars, focusing on their environmental context and detailed individual properties to bridge the gap between broad surveys and detailed star analyses.

Contribution

It provides a comprehensive overview of how focused surveys contribute to understanding Be stars as individual objects, complementing detailed single-star studies.

Findings

Insights into Be stars in binary systems

Effects of metallicity on Be star properties

Connections between surveys and star evolution

Abstract

The first half of the review dedicated to survey works on Be stars (Baade, Martayan, and Rivinius, this vol.) put emphasis on what we can learn from surveys about Be stars as a part of an environment, such as Be stars in binaries, Be stars in different metalicities, or Be stars as part of a star forming and then co-evolving group. This second half will rather concentrate on the information that more focused surveys can give on a Be star, understood as an individual object, and in this way attempts to bridge the gap between highly detailed single star studies, and necessarily broad survey and catalog work.
