| Abstract: | The near infrared photometry in the JHK bands is made for 20 Hipparcos carbon stars. Prom the results of the near infrared photometry, the bolometric corrections in the K band, the apparent bolometric magnitudes and the effective temperatures can be estimated. Combined with the trigonometric parallaxes observed with the Hipparcos satellite, the absolute bolometric magnitudes for some of the observed carbon stars can also be obtained. |
