The 21Na(p,γ)22Mg reaction is an important link in the synthesis of 22Na in oxygenneon novae, and serves as one of the first steps of the rp-process in x-ray bursts. This reaction has recently been studied at the TRIUMF-ISAC radioactive beam facility with the new DRAGON recoil separator. Resonant contributions have been measured for seven 22Mg states, from near the proton threshold to about 6 MeV in excitation energy. We report the results and their impact on the 21Na(p,γ)22 Mg reaction rate in novae and x-ray bursts.
