Molecular cloud cores are places where you might find: A) protostars B) Herbig-Haro objects C) molecular hydrogen (H₂) D) carbon monoxide (CO) E) all of the above

Question

Quizplus · Accepted Answer

Molecular cloud cores are regions of high density within molecular clouds where star formation occurs. These regions contain protostars, which are young stars in the process of formation, and Herbig-Haro objects, which are glowing shockwaves and jets of gas expelled by these protostars. Since molecular clouds themselves are primarily composed of molecular hydrogen, it is expected to find it in the molecular cloud cores. Additionally, carbon monoxide is often used as a tracer of molecular hydrogen, so it is also commonly found in these regions. Therefore, all of the options listed - protostars, Herbig-Haro objects, molecular hydrogen, and carbon monoxide - are typically found in molecular cloud cores.
