Description
Stellar spectroscopic classification has been successfully automated by
a number of groups. Automated classification and parameterization work
best when applied to a homogeneous data set, and thus these techniques
primarily have been developed for and applied to large surveys. While
most ongoing large spectroscopic surveys target extragalactic objects,
many stellar spectra have been and will be obtained. We briefly
summarize past work on automated classification and parameterization,
with emphasis on the work done in our group. Accurate automated
classification in the spectral type domain and parameterization in the
temperature domain have been relatively easy. Automated parameterization
in the metallicity domain, formally outside the MK system, has also been
effective. Due to the subtle effects on the spectrum, automated
classification in the luminosity domain has been somewhat more
difficult, but still successful. In order to extend the use of automated
techniques beyond a few surveys, we present our current efforts at
building a web-based automated stellar spectroscopic classification and
parameterization machine. Our proposed machinery would provide users
with MK classifications as well as the astrophysical parameters of
effective temperature, surface gravity, mean abundance, abundance
anomalies, and microturbulence.
