Horizontal Branch stars as AmFm/HgMn stars

TL;DR

This paper compares models and observations of horizontal branch stars with those of AmFm and HgMn stars, highlighting the limitations of current models across these stellar types.

Contribution

It provides a comparative analysis of models for different chemically peculiar stars, emphasizing their limitations based on recent observations.

Findings

Models for horizontal branch stars are limited compared to observations.

Comparative analysis reveals gaps in understanding of AmFm and HgMn stars.

Highlighting the need for improved models across stellar types.

Abstract

Recent observations and models for horizontal branch stars are briefly described and compared to models for AmFm stars. The limitations of those models are emphasized by a comparison to observations and models for HgMn stars.
