Near-infrared variability of a sample of galactic carbon Miras
Aims.In this paper we aim to determine the longest pulsation period of infrared carbon stars. Methods: .Forty-seven infrared carbon stars were selected based on (1) IRAS colours and spectral classification from the IRAS LRS atlas, and (2) known carbon stars with large CO expansion velocities. Multi-epoch JHKL'photometry was obtained. Results:
