We report observations of the CO(2-1) emission of SDSSJ1506+54, a compact(r_e~135pc) starburst galaxy at z=0.6. SDSSJ1506+54 appears to be forming starsclose to the limit allowed by stellar radiation pressure feedback models: themeasured L_IR/L'_CO 1500 is one of the highest measured for any galaxy. Withits compact optical morphology but extended low surface brightness envelope,post-starburst spectral features, high infrared luminosity (L_IR>10^12.5L_Sun), low gas fraction (M_H2/M_stars~15%), and short gas depletion time (tensof Myr), we speculate that this is a feedback- limited central starburstepisode at the conclusion of a major merger. Taken as such, SDSSJ1504+54epitomizes the brief closing stage of a classic model of galaxy growth: we arewitnessing a key component of spheroid formation during what we term a'redline' starburst.
