Exploring the temporal variation of the solar quadrupole moment from relativistic gravitation contributions: A fortuitous circumstance?
Rozelot, JP; Eren, Saliha (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-08)Due to its oblateness, the Sun carries a solar quadrupole moment playing a key role at the crossroad of fundamental solar physics, astrometry and celestial mechanics. There is nowadays a general agreement on its order of magnitude ( ≈2×10-7 ), but its temporal dependence is still poorly known. Helioseismology led to a variation within the solar cycle by less than 0.04%, not yet ...
