Herbig-Haro object
(HH, HHO)
(type of glowing nebula near protostars)
A Herbig-Haro object (HH or HHO) is a small,
glowing nebula resulting from the collision of the plasma
of a jet from a protostar with the surrounding ISM.
They are found on the order of a parsec from the protostar.
Sometimes a single such star has two HHs, from opposing jets.
They are found in star-forming regions, often near Bok globules.
