    • The spin and parity of the charmed mesons D*s+, D*0 and D*+ are determined for the first time to be JP = 1- with significances greater than 10σ over other hypotheses of 2+ and 3-, using an e+e- collision data sample with an integrated luminosity of 3.19 fb-1 collected by the BESIII detector at a center-of-mass energy of 4.178 GeV. Different spin-parity hypotheses are tested via a helicity amplitude analysis of the processes e+e--→ D*s+ D-s, D*0D0 and D*+D-, with D∗+s → D*+s γ, D∗0 → D0π0 , and D∗+ → D+π0. The results confirm the quark model predictions
