Newly discovered star opens 'laboratory' for solving cosmic dust mystery

Astronomers have discovered a stellar companion near a star with hot dust, offering a complex laboratory to understand the origin and composition of this phenomenon. This breakthrough builds on decades of technological leadership in interferometry, enabling scientists to study the interaction between the companion and the dust.
