【宇宙】こと座RR型変光星の脈動から “フラクタルパターン”を発見 - ハワイ大など
A team of researchers led by Dr John Lindner from the University of Hawaiʻi at Mānoa and the College of Wooster, Ohio,
has found evidence for fractal behavior in the pulsations of the so-called ‘golden’ RR Lyrae variables.
This false-color image shows the RR Lyrae variable KIC 5520878.
