Do you have a good definition of it or some good sources on the topic? I'm trying to sort out my own research so your input would be appreciated.

Thanks!

Coarticulation in phonetics refers to two different phenomena:

the assimilation of the place of articulation of one speech sound to that of an adjacent speech sound. For example, while the sound /n/ of English normally has an alveolar place of articulation, in the word tenth it is pronounced with a dental place of articulation because the following sound, /θ/, is dental.
the production of a coarticulated consonant, that is, a consonant with two simultaneous places of articulation. An example of such a sound is the voiceless labial-velar plosive /k͡p/ found in many West African languages.

Coarticulation may be generally defined as "the overlapping of adjacent articulations" (Ladefoged 1993: 55) or as two articulators "moving at the same time for different phonemes" (Borden and Harris 1984:130). Common examples from English are:

eight [eIt] vs. eighth [eIt]
keep [k+jip] vs. cool [kwul]

where the /t/ in "eighth" is dental (here transcribed [t]) when followed by the dental fricative [], and the /k/ of "keep" has a front-of-velar (transcribed [k+]), palatalized articulation when followed by the high front vowel [i]. The /k/ of "cool" is not so advanced, and is labialized.

I love the way people take simple concepts and work to make them seem hopelessly complicated (and thus worthy of a hefty salary!).

And the way some people seem to want to get paid based on the number of incorrect commas they insert in their explanations!
