Abstract:
The Planck satellite provides a set of all-sky maps at nine frequencies
from 30 GHz to 857 GHz. Planets, minor bodies, and diffuse
interplanetary dust emission (IPD) are all observed. The IPD can be
separated from Galactic and other emissions because Planck views a given
point on the celestial sphere multiple times, through different columns
of IPD. We use the Planck data to investigate the behaviour of zodiacal
emission over the whole sky at sub-millimetre and millimetre
wavelengths. We fit the Planck data to find the emissivities of the
various components of the COBE zodiacal model - a diffuse cloud, three
asteroidal dust bands, a circumsolar ring, and an Earth-trailing
feature. The emissivity of the diffuse cloud decreases with increasing
wavelength, as expected from earlier analyses. The emissivities of the
dust bands, however, decrease less rapidly, indicating that the
properties of the grains in the bands are different from those in the
diffuse cloud. We fit the small amount of Galactic emission seen through
the telescope's far sidelobes, and place limits on possible
contamination of the cosmic microwave background (CMB) results from both
zodiacal and far-sidelobe emission. When necessary, the results are used
in the Planck pipeline to make maps with zodiacal emission and far
sidelobes removed. We show that the zodiacal correction to the CMB maps
is small compared to the Planck CMB temperature power spectrum and give
a list of flux densities for small solar system bodies.
