摘要：

Broadband optical spectra are presented for 34 known and candidate nearby stars in the southern sky. Spectral types are determined using a new method that compares the entire spectrum with spectra of more than 100 standard stars. We estimate distances to 13 candidate nearby stars using our spectra and new or published photometry. Six of these stars are probably within 25 pc, and two are likely to be within the Research Consortium on Nearby Stars (RECONS) horizon of 10 pc.
