Multiplicity of disc-bearing stars in Upper Scorpius and Upper Centaurus-Lupus

Kuruwita, Rajika; Ireland, Michael; Rizzuto, Aaron C.; Bento, Joao; Federrath, Christoph


We present observations of disc-bearing stars in Upper Scorpius (US) and Upper CentaurusLupus (UCL) with moderate resolution spectroscopy in order to determine the influence of multiplicity on disc persistence after ∼5–20 Myr. Discs were identified using infrared (IR) excess from the Wide-field Infrared Survey Explorer (WISE) survey. Our survey consists of 55 US members and 28 UCL members, using spatial and kinematic information to assign a probability of membership. Spectra are gathered from...[Show more]
