[A complex #MagneticField detected on the surface of the star #vega ] Observations made using the SOPHIE spectrograph at the Haute Provence Observatory, and spectropolarimetry with the Narval and Neo-Narval instruments at the Bernard Lyot Telescope at the Pic du Midi Observatory, have enabled IRAP researchers to detect the coexistence, on the surface of the star Vega, of a complex magnetic field : one described as #fossil, the second as #variable : https://www.irap.omp.eu/en/2025/10/detection-of-a-complex-magnetic-field-on-thesurface-of-the-intermediate-mass-star-vega/

As we transition from Mahoe Hope to ʻIkuwā, that same sky is full of stars that served as important navigation
