The Arc in the DX Cha Circumbinary System: Evidence for a Retrograde Circumbinary Disk
Observations of the binary system DX Chamaeleontis (DX Cha, HD 104237) reveal a compact, asymmetric ring structure with a radius of 0.43 au. This ring is just outside the binary orbit, which has a semimajor axis of a _b = 0.22 au and eccentricity of e _b = 0.665, placing the ring at ≈1.2 times the...
