LBV

"One possibility is that we are seeing the end of an LBV eruption of a surviving star, with a mild drop in luminosity, a shift to hotter effective temperatures, and some dust obscuration," the authors write.

"Alternatively, the LBV could have collapsed to a massive black hole without the production of a bright supernova."

Mrs. Sackler, 34, is the proprietress of LBV, a private social club, from where this collection, LBV Care of Joss Sackler, grew.

LBV grew out of a separate interest, in wine.

LBV, she was somewhat hesitant to admit, stood for Les Bouledogues Vigneronnes: the winemaking bulldogs.
