Investigation on uncertain RRab variable stars from ASAS-SN catalogue

TL;DR

This paper analyzes seven uncertain RRab variable stars from the ASAS-SN catalogue by comparing their positions in the H-R diagram with a sample of confirmed RRab stars from public databases.

Contribution

It provides a comparative analysis to clarify the classification of uncertain RRab stars using H-R diagram positioning.

Findings

Some uncertain RRab stars align with confirmed RRab stars in the H-R diagram.

The study helps refine classification criteria for RRab variable stars.

Results support improved identification methods for variable star classification.

Abstract

An analysis of a group of seven variables stars, classed by ASAS-SN as uncertain RRab, is performed comparing their position in a H-R diagram with respect to a sample of variables of the same type built from public astronomical databases.
