HD 83058 has generally been considered to be a single star,[8] but high-resolution spectra show it to be a double-lined
spectroscopic binary.[9] The two components have approximately the same
spectral type.[4] Line-profile variations have been detected which suggest that at least one component pulsates, as is common for stars of this spectral class.[10]
HD 83058 was proposed as a
runaway star from a
supernova explosion. However, the discovery that it is a binary makes this unlikely.[4]
