Radio and X-ray data on four old Type IIn supernovae show mass-loss rates 1-2 orders of magnitude below optical estimates, indicating rapidly evolving progenitor winds over the final centuries before explosion.
Age dating of R127 and R128 clusters shows the brightest stars are peculiar relative to single-star models, with implications for binary-driven LBV evolution.
