Is Cepheus A East a Herbig-Haro object?

open access: yesThe Astronomical Journal, 1993
Cepheus A remains a unique radio object. It consists of lines of about 13 H II regions, each of which, it was originally suggested, was produced by a B3 star. However, since the lifetime of each H II region was not expected to be greater than about 1000 years, it was difficult to explain how 13 stars could all be in the same stage of evolution inside ...

CCD images of suspected Herbig-Haro objects

open access: yesThe Astrophysical Journal Supplement Series, 1985
We present CCD images in V, R, I, and H..cap alpha.. of ten regions suspected to contain Herbig-Haro objects, including 11 of the 37 HH candidates listed by Gyulbudaghian et al. (1978). Four of these 11 are HH objects; the rest are either nebulous stars, reflection nebulae, or plate flaws.

The molecular condensations ahead of Herbig-Haro objects

open access: yes, 2003
Clumps of enhanced molecular emission are present close to a number of Herbig-Haro (HH) objects. These enhancements may be the consequence of an active photochemistry driven by the UV radiation originating from the shock front of the HH object.
