Complete set of quasiconserved quantities for spinning particles around Kerr Speaker(s): Adrien Druart
Abstract: I will revisit the conserved quantities of the MathissonPapapetrouTulczyjew equations describing the motion of spinning particles around a fixed background. Assuming Ricciflatness and the existence of a KillingYano tensor, I obtain three nontrivial quasiconserved quantities, i.e. conserved at linear order in the spin, thereby completing the two quasiconstants of motion found by RĂ¼diger with one new independent quasiconstant of motion. Finally, I will discuss the implications for the motion of spinning particles in the Kerr geometry.
