High-velocity gas in the Monoceros loop
The interstellar Na i lines arising from high-velocity gas in the Monoceros loop supernova remnant have been observed. When combined with previously published interstellar Ca measurements, the interstellar lines in the high-velocity component of HD 47359 show an abnormally low ratio Na i/Ca ii.
