A low-mass companion desert among intermediate-mass visual binaries: The scaled-up counterpart to the brown dwarf desert

G. Duchene, J. T. Oon, R. J. De Rosa +8

We present a high-contrast imaging survey of intermediate-mass (1.75--4.5 $M_{\odot }$) stars to search for the most extreme stellar binaries, i.e., for the lowest mass stellar compan…
