Improved precision on the radius of the nearby super-Earth 55 Cnc e

We report on new transit photometry for the super-Earth 55 Cnc e obtained with Warm Spitzer/IRAC at 4.5 μm. An individual analysis of these new data leads to a planet radius of [superscript 2.21]+0.15 [over] -0.16 R[subscript ⊕], which agrees well with the values previously derived from the MOST and...
