S-BGLS periodograms of YV2 for the star HD48948, focused on three frequency ranges (7.3, 38 and 151 d). The absolute value of log P has no meaning; instead, the relative values ​​of log ⁡P have meaning. The signal observed at approximately 42 d in the middle panel represents the unstable activity feature. Credit: Monthly notices … Read more
