Herbig Haro objects in the Pelican

[Avdhoeven]

Jets are an active, short-lived phase of star formation, lasting only about 100 000 years. They are called Herbig-Haro (HH) objects, named after George Herbig and Guillermo Haro, who studied the outflows in the 1950's. Astronomers still don’t know what role jets play in the star formation process or exactly how the star unleashes them.

Although Herbig–Haro (HH) objects come in a wide array of shapes, the basic configuration is usually the same. Twin jets of heated gas, ejected in opposite directions from a forming star, stream through interstellar space.

In the Pelican Nebula several Herbig-Haro objects can be found. Recently I bought pixinsight and reprocessed some older data from the Pelican. It showed that 7 HH objects can be seen on this image. It's clear this is a star-forming region....

Very nice

That's very interesting You will enjoy using PI when you get to know it, some excellent routines for accessing the detail locked in the image data
