We present results derived from four stellar occultations by the plutino object (208996) 2003. AZ(84), detected on 2011 January 8 (single-chord event), 2012 February 3 (multi-chord), 2013 December 2 (single-chord), and 2014 November 15 (multi-chord). Our observations rule out an oblate spheroid solution for 2003. AZ(84)'s shape. Instead, assuming hydrostatic equilibrium, we find that a Jacobi triaxial solution with semiaxes (470 +/- 20) x (383 +/- 10) x (245 +/- 8) km can better account for all… Expand
