Bolometric Correction of the roAp star $\alpha$ Cir

TL;DR

This paper determines the bolometric correction for the roAp star α Cir using spectroscopic and photometric data, enabling its placement in the HR diagram for the first time.

Contribution

It provides the first bolometric correction for α Cir, derived from integrated flux estimates based on literature data.

Findings

Two bolometric correction values obtained.

α Cir accurately placed in the HR diagram.

Method demonstrates use of combined spectroscopic and photometric data.

Abstract

For the first time, the bolometric correction of $\alpha$ Cir was determined. Two values, both based on an estimation of the total integrated flux, were obtained. For that purpose spectroscopic and photometric data of $\alpha$ Cir available in the literature was used. The values derived were then used to place $\alpha$ Cir in the HR diagram.
