Dynamic Imprints of Colliding-wind Dust Formation from WR 140

Dynamic Imprints of Colliding-wind Dust Formation from WR 140

Carbon-rich Wolf–Rayet (WR) binaries are a prominent source of carbonaceous dust that contribute to the dust budget of galaxies. The “textbook” example of an episodic dust-producing WR binary, WR 140 (HD 193793), provides us with an ideal laboratory for investigating the dust physics and kinematics...
