Discovery of a very cool object with extraordinarily strong Hmathsf α emission
We report on the finding of the strongest Hα emission - pseudoequivalent width of 705 Å- known so far in a young, late type dwarf. This object, named as S Ori 71, is a substellar candidate member of the 1-8 Myr star cluster sigma Orionis. Due to its overluminous location in color-magnitude diagrams, S Ori 71 might be younger than other cluster
