ABSTRACT

We present our observations of a very late-type faint member of the R Coronae Australis star-forming cloud that displays an unusually rich emission-line spectrum, similar to that of more massive counterparts, in which both accretion and outflow signatures coexist. This is the latest-type object for which such an intense emission-line spectrum has been observed so far. The late-type spectrum and the faintness of the underlying object suggest that it is near or below the borderline separating stars from brown dwarfs, showing that such spectacular spectral signatures can be present even at masses of a few percent of a solar mass.
