Determining the evolutionary stage of HD163899 on the basis of its oscillation spectrum

TL;DR

This paper reinterprets the oscillation spectrum of HD 163899 using new stellar parameters, suggesting it may be more massive and possibly still in the main sequence stage, thus refining its evolutionary classification.

Contribution

It introduces a new interpretation of HD 163899's oscillation spectrum based on updated stellar parameters, challenging previous evolutionary stage assumptions.

Findings

Star could be more massive than previously thought

Star may still be in the main sequence stage

Oscillation spectrum helps determine evolutionary stage

Abstract

We present the new interpretation of the oscillation spectrum of HD 163899 based on the new determinations of the effective temperature, mass-luminosity ratio and rotational velocity. These new parameters strongly prefer the more massive models than previously considered. Now it is also possible that the star could be in the main sequence stage. Using the oscillation spectrum as a gauge, we intend to establish which stage of evolution corresponds better to HD 163899.
