Spitzer Space Telescope photometry and spectroscopy of BD +20 307 show that all of the dust around this remarkable Gyr-old spectroscopic binary arises within 1 AU. No additional cold dust is needed to...
Large Scale Traces of Solar System Cold Dust on CMB Anisotropies
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/24
We explore the microwave anisotropies at large angular scales produced by the emission from cold and large dust grains, expected to exist in the outer parts of the Solar System, using a simple toy mod...
