摘要：
We report the detection of over 400 classical novae in eruption in the giant elliptical galaxy M87. Ten epochs of observation were assembled from archival Hubble Space Telescope WFPC2 observations. This dataset yielded the spatial distribution of the M87 novae: the novae closely follow the light of the galaxy. The instantaneous luminosity function of the M87 novae was also obtained: it is similar to that of M31 and M81, but with a significant and surprising number of decidedly super-Eddington objects. A 30 day HST campaign on M87 detected a number of equally surprising novae that are always SUB-Eddington.
