When infrared astronomy began, those previously annoying dust particles were observed to be significant and vital components of astrophysical processes.

Comparing mass and light typically involves assumptions about complicated astrophysical processes.

The free-fall time is a very useful estimate of the relevant timescale for a number of astrophysical processes.

No astrophysical process is likely to generate prime numbers.

These isotopic signatures often fingerprint very specific astrophysical nuclear processes, that took place within the parent star and prove their extra-Sol origin.

This is produced by sub-atomic particle interactions, including those in certain astrophysical processes.

Indeed many astrophysical processes, such as the spreading out of gas by galactic winds and supernovae, would decrease the local baryon fraction.

There are a number of astrophysical processes which are believed to be responsible for nucleosynthesis.

Unfortunately, most of these thought experiments presume a more detailed knowledge of astrophysical processes than astronomy now possesses.

In his scientific work, Lightman has made fundamental contributions to the theory of astrophysical processes under extreme temperatures and densities.
