| Abstract: | Infrared photometry in the J,H and K bands of 24 carbon stars is presented. Their distribution in the (J-H) — (H-K) two-colour diagram is described and their bolometric corrections and bolometric magnitudes are given. The derivation of the bolometric correction from the J-K colour index is shown to be feasible. The results obtained agree well with those obtained by other means.The effective temperature of the stars was derived in two different ways. We suggest that, pending accurate measurement of its angular diameter, the effective temperature of a carbon star may be evaluated by using Te=7070/(J-K)J + 0.88]. |
