Scientific paper

We cross-identified AKARI-Hipparcos and AKARI-2MASS combined catalogs with the following astronomical catalogs using a tolerance radius of 3 arcsec: (1) S-type stars, i.e., stars with surface carbon-to-oxygen number ratio (C/O) close to unity: Stephenson (1984, Cat. , 1990AJ....100..569S), who list 1,412 sources; (2) post-AGB stars: Szczerba et al. (2007, Cat. ), who list 326 very likely post-AGB stars; (3) planetary nebulae: Acker et al. (1994, Cat. V/84>), who list 1,143 sources; (4) Wolf-Rayet stars: van der Hucht (2001, Cat. ), who list 226 sources; (5) Be stars: Zhang et al (2005, Cat. ), who list 1,185 sources. We further searched the SIMBAD database for known carbon stars, OH/IR stars, PMS stars, and YSOs, by querying by object types of 'C*' , 'OH*', 'pMS*', and 'Y*O', respectively. Also, M-type giants and supergiants are extracted from the SIMBAD database by querying by spectral types of 'M' and luminosity class of 'III (giants)' and 'I (supergiants)', respectively. Occasionally, more than one object type are found (within a search radius of 3 arcsec) for a single object in the SIMBAD database. In those cases, we keep both of types. The electronic tables for these data sets are provided.
