The year 1995 was big for astronomers, with the discovery of the first planet beyond our solar system - an exoplanet - also being announced. Until Gliese 229B's discovery, the existence of brown dwarfs had only been hypothesized. But there were anomalies about Gliese 229B, particularly after its mass was measured at about 71 times that of Jupiter.
"This didn't make any sense since an object of that mass would be much brighter than Gliese 229B," said Caltech astronomer Jerry Xuan, lead author of one of the studies, published in the journal Nature, opens new tab.
"In fact, some models predict that objects with masses above 70 Jupiter masses fuse hydrogen and become stars, which was clearly not happening here."
O valor de 80 deve então ser o que reúne o consenso de todos os modelos, e não apenas de alguns como citado. No entanto, antes desta descoberta estavam à espera que o objecto tivesse um brilho maior do que o observado, dada a sua massa.
