  • We report the detection of seven low-mass companions to intermediate-mass stars (SpT B/A/F; ~ 1.5–4.5 M_⊙) in the Scorpius–Centaurus (Sco–Cen) Association using nonredundant aperture masking interferometry. Our newly detected objects have contrasts ΔL' ≈ 4–6, corresponding to masses as low as ~20 M_(Jup) and mass ratios of q ≈ 0.01–0.08, depending on the assumed age of the target stars. With projected separations ρ ≈ 10–30 AU, our aperture masking detections sample an orbital region previously… CONTINUE READING
