Herbig Haro objects 161/164

Herbig Haro objects 161/164 (abbreviated to HH 161/164) are located at a distance of around 1,120 light years in the constellation of Cassiopeia.

The objects are associated with a source known as IRAS 00087+5833. The latter is within the dark cloud LDN 1265. Such regions are areas where star formation takes place, thus it has attracted interest amongst astronomers, where several young stellar objects have been detected.

Two Herbig Haro objects (i.e., HH 161 and HH 164) are associated with the young stellar object LkH╬▒ 198 (also known as V 633 Cas) and it is classified as a Herbig Ae/Be star. In optical images they appear as partial horseshoes.

Nearby is another young stellar object known as V376 Cas, another Herbig Ae/Be star, which is associated with the Herbig Haro object, HH 162.

Due to the fact that both stars are very young, they are still surrounded by left over material from their formation.
