The Small Separation A-star Companion Population: Tentative Signatures of Enhanced Multiplicity with Primary Mass

The Small Separation A-star Companion Population: Tentative Signatures of Enhanced Multiplicity with Primary Mass

We present updated results from our near-infrared long-baseline interferometry (LBI) survey to constrain the multiplicity properties of intermediate-mass A-type stars within 80 pc. Previous adaptive optics surveys of A-type stars are incomplete at separations <20 au. Therefore, an LBI survey allo...
