  We report the detection of seven low mass companions to intermediate-mass
stars (SpT B/A/F; $M$$\approx$1.5-4.5 solar masses) in the Scorpius-Centaurus
Association using nonredundant aperture masking interferometry. Our newly
detected objects have contrasts $\Delta L'$$\approx$4-6, corresponding to
masses as low as $\sim$20 Jupiter masses and mass ratios of
$q$$\approx$0.01-0.08, depending on the assumed age of the target stars. With
projected separations $\rho$$\approx$10-30 AU, our aperture masking detections
sample an orbital region previously unprobed by conventional adaptive optics
imaging of intermediate mass Scorpius-Centaurus stars covering much larger
orbital radii ($\approx$30-3000 AU). At such orbital separations, these objects
resemble higher mass versions of the directly imaged planetary mass companions
to the 10-30 Myr, intermediate-mass stars HR 8799, $\beta$ Pictoris, and
HD95086. These newly discovered companions span the brown dwarf desert, and
their masses and orbital radii provide a new constraint on models of the
formation of low-mass stellar and substellar companions to intermediate-mass
stars.
