TL;DR
This paper analyzes the variability of HD 170699, a high-rotation Delta Scuti star observed by COROT, identifying a primary period and multi-periodic behavior, highlighting the need for further frequency analysis.
Contribution
It provides the first detailed variability analysis of HD 170699, revealing its multi-periodic nature and emphasizing the importance of additional frequency data.
Findings
Detected a primary period of 10.45 c/d with 5.29 mmag amplitude
Star exhibits multi-periodicity requiring more frequencies for modeling
Highlights the star's high rotational velocity and non-evolutionary status
Abstract
We present the analysis of the variability of HD 170699, a COROT star showing the characteristics of a non evolutionary Delta Scuti star with high rotational velocity. There is a clear period of 10.45 c/d with 5.29 mmag amplitude in the y filter. From the data, it can be seen that the star shows multi-periodicity and it is necessary to add more frequencies to adjust the observations
