J P Rozelot

J.P. Rozelot is a French solar physicist renowned for his extensive contributions to solar research over five decades, particularly at the Pic du Midi Observatory where he focused on spectroscopy of iron lines and solar oblateness. He has authored key papers on historical solar grand minima, solar magnetism, and perihelion precession influenced by solar oblateness variations. His work emphasizes the role of plasma and magnetism in the baryonic universe and revisits fundamental solar measurements for astrophysical relevance.
