Mira variables pulsate with a period between 80 and 1000 days. In visual light, the amplitude of the light change is in general between 2.5 and 10 magnitudes. In infrared the amplitude is significantly smaller. Miras are of spectral type M, S or C, dependent on the ratio between the amount of carb...

IRC +10216 or CW Leonis is the best studied carbon star, but also a very peculiar one with the central star being embedded in a thick dust envelope. Therefore, its energy is emitted mostly at infrared wavelengths: in fact, IRC +10216 is the brightest object in the sky at a wavelength of 10 m. Recent spec...
