J/AJ/134/214        Infrared study of J-type carbon stars    (Chen+, 2007)

Infrared study of J-type carbon stars based on Infrared Astronomical Satellite, Two Micron All Sky Survey, and Infrared Space Observatory data. Chen P.-S., Yang X.-H., Zhang P. <Astron. J., 134, 214-222 (2007)> =2007AJ....134..214C
ADC_Keywords: Infrared sources ; Stars, carbon ; Photometry, infrared Keywords: infrared: stars - stars: carbon - stars: late-type Abstract: We collected 113 J-type carbon stars from the published literature. Observations from 2MASS, IRAS, and ISO show that, except for silicate carbon stars in the J-type carbon star domain, the infrared properties of the other J-type carbon stars are quite similar to those of ordinary carbon stars. The above results imply that the chemical peculiarity of enhanced 13C for J-type carbon stars is not reflected in the infrared region. In addition, the possible evolutionary scenario and binarity for J-type carbon stars are also discussed. File Summary:
