Magnetic activity and differential rotation of HIP12653
Amina Boulkaboul, Lotfi Yelles Chaouche, Alessandro C. Lanzafame +1
We present a spectroscopic and photometric study of HIP12653 to investigate its magnetic cycle and differential rotation. Using HARPS archival spectra matched with MARCS-AMBER theo…
