VLTI-MATISSE L- and N-band aperture-synthesis imaging of the unclassified B[e] star FS Canis Majoris

Understand

Context: FS Canis Majoris (FS CMa, HD 45677) is an unclassified B[e] star surrounded by an inclined dust disk.

• The evolutionary stage of FS CMa is still debated.
• Perpendicular to the circumstellar disk, a bipolar outflow was detected.
• Infrared aperture-synthesis imaging provides us with a unique opportunity to study the disk structure.
