Modeling KIC10684673 and KIC12216817 as Single Pulsating Variables

TL;DR

This study models the light curves of KIC 10684673 and KIC 12216817 as single pulsating delta Scuti stars, providing a simpler explanation for their variability than eclipsing binary systems.

Contribution

The paper demonstrates that the variability of these two Kepler objects can be effectively modeled as single delta Scuti pulsators, challenging their previous classification as uncertain eclipsing binaries.

Findings

Light curves are consistent with delta Scuti pulsations.

Eclipsing binary scenario remains possible but less likely.

Modeling simplifies understanding of these stars' variability.

Abstract

The raw light curves of both KIC 10684673 and KIC 12216817 show variability. Both are listed in the Kepler Eclipsing Binary Catalog (hereafter KEBC), however both are flagged as uncertain in nature. In the present study we show their light curves can be modeled by considering each target as a single, multi-modal delta Scuti pulsator. While this does not exclude the possibility of eclipsing systems, we argue, while spectroscopy on the systems is still lacking, the delta Scuti model is a simpler explanation and therefore more probable.
