K 1-6 is a photoionised ISM nebula shaped by a fast-moving hot white dwarf in a triple system

Jaroslav Merc, David Jones, Ana Escorza +22

K 1-6 has long been classified as a planetary nebula (PN) hosting a binary central star, yet it has remained poorly studied due to its faintness. The central star exhibits pronounc…
