“LSST will enable early detection of prototype cases for a number of theoretically predicted explosive transients which we’ve already discussed, including orphan GRB afterglows, accretion induced collapse events, fall-back and pair-instability supernovae, and the so called SN 0.Ia.” pg 267

“AM CVn binaries are extremely rare relatives of cataclysmic variables with ultra-short orbital periods; the most extreme cases have orbital periods of tens of minutes, arguably encompassing the shortest orbital periods of any known class of binaries” pg 288

LBVs pg 296

“LSST will also address the issue of the eruptive variability found in a rare class of young stellar objects - the FUor and EXor stars. FUor and EXor variables are named after the prototypes FU Orionis (Hartmann & Kenyon 1996) and EX Lupi (Herbig et al. 2001) respectively. These stars exhibit outburst behavior characterized by an up to 6 magnitude increase in optical brightness, with high states persisting from several years to many decades. Both classes of objects are interpreted as pre-main sequence stars undergoing significantly increased mass accretion rate possibly due to instabilities in the circumstellar accretion disk.” pg 298

” PTF will discover hundreds of supernovae and possibly several rare events such as “0.Ia”, Luminous Red Novae (LRNe) and Macronovae (MNe) per year. The LSST (Deep Wide Fast Survey) will discover hundreds of rare events in the Local Universe.” pg 255
