Radio continuum monitoring of the extreme carbon star IRC+10216.

Abstract (from CDS):

We describe Very Large Array observations of the extreme carbon star IRC+10216 at 8.4, 14.9, and 22.5GHz made over a two year period. We find possible variability correlated with the infrared phase and a cm- to sub-millimeter wavelength spectral index very close to 2. The variability, observed flux densities, and upper limit on the size are consistent with the emission arising from the stellar photosphere or a slightly larger radio photosphere.
