I need to translate the following title of a scientific paper into Latin – indeed, Neo-Latin, with neologisms, but keeping classical grammar as much as possible. It is: 'On the influence of dark matter on stellar formation and evolution.' I am struggling with finding a classical word for 'influence'.
For "influence" I would suggest effectus, us, which can be combined with in + acc. to say "effect on something." (Don't go looking for this in the dictionaries; but peruse a Google search like this for many examples.)
So you end up with something like:
De effectu materiae obscurae in genesim (?) stellarum, etc.
Honestly I find "formation" and "evolution" trickier to find classical equivalents for (certainly not evolutio, for example). De quibus quidem non rogasti.
