Stellar classification from simulated DIVA spectra. I. Solar metallicity stars
. The orbiting telescope with the Double Interferometer for Visual Astrometry (DIVA) will obtain, apart from astrometry, low-resolution spectra (A/AA ~ 20) covering the optical range (350 to 1000 nm) for over 10 million stars.

Quantitative Stellar Classification with Low-Resolution Spectroscopy [PDF]
AbstractLow-resolution spectroscopy (R ≈ 1000) is used to efficiently characterize faint stars suspected to host planets. Stellar parameters, i.e. effective temperature, surface gravity, and metallicity can be assessed from these spectra by methods of quantitative classification.

Automated Stellar Classification for Large Surveys with EKF and RBF Neural Networks [PDF]
An automated classification technique for large size stellar surveys is proposed. It uses the extended Kalman filter as a feature selector and pre-classifier of the data, and the radial basis function neural networks for the classification.

Mira variables in the Milky Way’s nuclear stellar disc: discovery and classification [PDF]
The properties of the Milky Way’s nuclear stellar disc give crucial information on the epoch of bar formation. Mira variables are promising bright candidates to study the nuclear stellar disc, and through their period–age relation dissect its star ...
