DENIS-P J1901391-370017: IS A YOUNG VERY LOW-MASS STAR OR A LOW-MASS BROWN DWARF IN CORONA-AUSTRALIS?

Abstract

DENIS-P J1901391-370017 has been identified as a low-mass brown dwarf in the Corona-Australis cloud. This paper presents our mass estimate of this brown dwarf. The dereddened spectral energy distribution of the source indicates that DENIS-P J1901391-370017 is a very low-mass star, not a low-mass brown dwarf, as previously reported. We also reconfirm that DENIS-P J1901391-370017 is diskless, as previously mentioned in the literature
