We present results from 28 stellar occultations by the large Trans Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultation data set, along with other 9 published events, we were able to fit an oblate ellipsoid shape, with equatorial semi axes, a and b of 566.1+2.5 2.2 km, and a polar semi axis, c, of 511.2+3.6 3.7 km. It provides an equivalent volumetric...
