Carbon-rich dust injected into the interstellar medium by Galactic WC binaries survives for hundreds of years
Some carbon-rich Wolf-Rayet stars (WC stars) show an infrared excess from dust emission. Dust forms in the collision of the WC wind with a companion star's wind. As this dust is carried towards the ISM at close to the WCd wind speed and the binary continues through its orbit, a spiral structure forms around the system. The shape depends on the orbital eccentricity and period, as well as stellar parameters like mass-loss rates and terminal wind speeds. Imaging of the WCd binary WR 140 with JWST/…

Plant markers enough for years. Brought back from the off-grid festival washing up station, given a good hosing off and dried in the sun. Score! #reuse
