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 کاملStable chaos in the 55 Cnc exoplanetary system ?
The five planets discovered around the main-sequence star 55 Cnc may represent a case of stable chaos. By using both the Frequency Map Analysis and MEGNO we find that about 15 % of the systems that can be build from the nominal orbital elements of the system are highly chaotic. However, in spite of the fast diffusion rate in the phase space, the planetary system is not destabilized over 400 Myr...
متن کاملPlanetpol polarimetry of the exoplanet systems 55 Cnc and τ Boo ⋆
We present very sensitive polarimetry of 55 Cnc and τ Boo in an attempt to detect the partially polarised reflected light from the planets orbiting these two stars. 55 Cnc is orbited by a hot Neptune planet (55 Cnc e) at 0.038 AU, a hot Jupiter planet (55 Cnc b) at 0.11 AU, and at least 3 more distant planets. The polarisation of this system is very stable, showing no sign of the periodic varia...
متن کاملThe HORUS Processor
Designing a complete SoC or reuse SoC components to create a complete system is a common task nowadays. The flexibility offered by the design flow used offers the designer an unprecedented capability to incorporate more and more demanded features like error detection and correction mechanisms to increase the system dependability. This paper describes the design of the HORUS processor, a RISC pr...
متن کاملCould the 55 Cnc Planetary System Really Be in the 3:1 Mean Motion Resonance?
We integrate the orbital solutions of the planets orbiting 55 Cnc. In the simulations, we find that not only three resonant arguments θ1 = λ1−3λ2 + 2ω̃1, θ2 = λ1 − 3λ2 + 2ω̃2 and θ3 = λ1 − 3λ2 + (ω̃1 + ω̃2) librate respectively, but the relative apsidal longitudes ∆ω also librates about 250◦ for millions of years. The results imply the existence of the 3:1 resonance and the apsidal resonance for th...
