Detection of a transit of the super-Earth 55 Cancri e with warm Spitzer
We report on the detection of a transit of the super-Earth 55 Cnc e with warm Spitzer in IRAC’s 4.5 μm band. Our MCMC analysis includes an extensive modeling of the systematic effects affecting warm Spitzer photometry, and yields a transit depth of 410 ± 63 ppm, which translates to a planetary radiu...

| description | We report on the detection of a transit of the super-Earth 55 Cnc e with warm Spitzer in IRAC’s 4.5 μm band. Our MCMC analysis includes an extensive modeling of the systematic effects affecting warm Spitzer photometry, and yields a transit depth of 410 ± 63 ppm, which translates to a planetary radius of 2.08[+0.16 over -0.17]R[subscript ⊕] as measured in IRAC 4.5 μm channel. A planetary mass of 7.81[+0.58 over -0.53]M[subscript ⊕] is derived from an extensive set of radial-velocity data, yielding a mean planetary density of 4.78[+1.31 over -1.20] g cm[superscript -3]. Thanks to the brightness of its host star (V = 6, K = 4), 55 Cnc e is a unique target for the thorough characterization of a super-Earth orbiting around a solar-type star. |
