Thanks, Gary, it’s a bit clearer now.

IR radiation is basically heat so the collisions of the particles coming from the star with cooler gas must generate heat/IR which gets thru the dust better than visible or UV. And this is heat as opposed to radiation coming from changes in electron orbitals?

As I understand the physics, charged particles can be emitted from the polar regions of the stars magnetic fields, forming the aforementioned “beams” but they’re not generally observable unless the beams interact with a gas cloud.

It is mentioned that the new stars emit gases in “beams” and I am having a hard time visualizing this.

Could you perhaps tweak the analogy? Beams to me mean the gases are coming out in spots and not uniformly.

If there are PAHs, there must be a carbon-rich environment. It the carbon coming from the young stars, too? Is it formed by fusion in the stars or was it in the material that accreted to form them in the first place?

Ah, thanks Christine! You would be able to find out, I suppose.
