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 2.21+0.15 −0.16 R⊕, which agrees well with the values previously derived from the MOST and Spitzer transit discovery data. A global analysis of both Spitzer transit time-series improves the precision on the radius of the...
متن کاملDetection 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 radius of 2.08 −0.17 R⊕ as measured in IRAC 4.5 μm channel. A planetary mass of 7.81 +0.58 −0.53 M⊕ is d...
متن کاملSeparating E from B
In a microwave background polarization map that covers only part of the sky, it is impossible to separate the E and B components perfectly. This difficulty in general makes it more difficult to detect the B component in a data set. Any polarization map can be separated in a unique way into " pure E, " " pure B, " and " ambiguous " components. Power that resides in the pure E (B) component is gu...
متن کاملMelting in super-earths.
We examine the possible extent of melting in rock-iron super-earths, focusing on those in the habitable zone. We consider the energetics of accretion and core formation, the timescale of cooling and its dependence on viscosity and partial melting, thermal regulation via the temperature dependence of viscosity, and the melting curves of rock and iron components at the ultra-high pressures charac...
متن کاملA Class E Power Amplifier with Low Voltage Stress
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
