Period analysis of HR 7275 for different activity indicators.
| Activity Indicator | PLS (days) | PPDM (days) |
|---|---|---|
| CaIIIRT-2 | 28.0 ± 0.1 | 28.0 ± 0.2 |
| CaIIH | 27.8 ± 0.1 | 27.8 ± 0.3 |
| CaIIK | 27.8 ± 0.1 | 27.8 ± 0.3 |
| Hα | 14.2 ± 0.4 | 14.2 ± 0.5 |
| ∆T | 28.2 ± 0.1 | 14.2 ± 0.1 |
| RV residuals | 13.6 ± 0.3 | 27.2 ± 0.4 |
Notes. Rotational period is determined by using different activity indicators with two methods; Lomb-Scargle (LS) and phase dispersion minimization (PDM). While the Ca IIIRT and H&K lines demonstrate emission modulation with approximately the orbital period (≃28 days), the Hα and RV residuals show half-period (≃14 days) due to the configuration by multiple spots.
