Abstract
Among all the fundamental solar parameters, mass, diameter, surface gravity, temperature, luminosity…, all well inventoried since several years in reference books, multi-gravitational moments are not yet well documented. Several theoretical estimates have been proposed through different approaches, mainly theory of Figure, helioseismology. We will show their own merits. Exact values of multipolar gravitational moments are important as they are at the crossroads of solar physics, solar astrometry, celestial mechanics, and General Relativity. Their temporal variations are still often neglected; they are yet an essential aspect for constraining solar-cycle modeling or solar-evolution theories. They induced planet-planet inclinations in multi-transiting systems gravitating in the neighboring of a star. This paper emphasizes some key issues to understand the role of these parameters.
