| Abstract: | We present photometric and spectroscopic data on a subset of over 30 oxygen-rich Long Period Variable (LPV) stars which we
have been monitoring between 8/95 & 4/97. With these data, we are attempting to ascertain the relationship of dust formation
to optical period. Our ultimate goal is to determine what conditions lead to dust formation and destruction in these environments,
and whether or not an evolutionary sequence can be inferred for AGB stars also based on their spectra and dust formation.
