TL;DR
This paper introduces a straightforward phenomenological method for detrending raw Kepler and MOST photometric data, demonstrated on two chemically peculiar stars, and identifies one as a magnetic chemically peculiar star with ACV variability.
Contribution
The paper presents a new simple detrending method applicable to various periodically variable objects in satellite and ground-based photometry.
Findings
Successfully applied to two stars, KIC 6950556 and HD 37633.
Identified KIC 6950556 as a magnetic chemically peculiar star with ACV variability.
Demonstrated broad applicability of the detrending method.
Abstract
We present a simple phenomenological method for detrending of raw Kepler and MOST photometry, which is illustrated by means of photometric data processing of two periodically variable chemically peculiar stars, KIC 6950556 and HD 37633. In principle, this method may be applied to any type of periodically variable objects and satellite or ground based photometries. As a by product, we have identified KIC 6950556 as a magnetic chemically peculiar star with an ACV type variability.
