Abstract

Solar gravitational multipolar moments have not been yet extensively analyzed. However, they are at the crossroads of solar physics, solar astrometry, celestial mechanics and General Relativity. Their values reflect the physics of solar models: non-rigid rotation, solar latitudinal rotation, solar- core properties, solar-cycle variations and structure evolution. 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 multitransiting systems gravitating in the neighboring of a star, leading to key issues future studies. This paper is devoted to an analytical analysis; a second part will address an helioseismology analysis.
