A new paradigm of governance for a carbon-pricing system [PDF]
, 2016 Throughout its life, the United Nations has played a pioneering role in the world of ideas. COP21 – also known as Paris 2015 – shows the path for the United Nations to establish a new governance that will enforce the compliance of a new planetary carbon ...

Stability and Formation of the Resonant System HD 73526 [PDF]
, 2007 Based on radial velocity measurements it has been found recently that the two giant planets detected around the star HD 73526 are in 2:1 resonance. However, as our numerical integration shows, the derived orbital data for this system result in chaotic ...

Earth-like Habitats in Planetary Systems
, 2014 Understanding the concept of habitability is related to an evolutionary knowledge of the particular planet-in-question. Additional indications so-called "systemic aspects" of the planetary system as a whole governs a particular planet's claim on ...

The fragility of planetary systems [PDF]
, 2015 We specify the range to which perturbations penetrate a planetesimal system. Such perturbations can originate from massive planets or from encounters with other stars.

The 1:1 resonance in Extrasolar Systems: Migration from planetary to satellite orbits
, 2011 We present families of symmetric and asymmetric periodic orbits at the 1/1 resonance, for a planetary system consisting of a star and two small bodies, in comparison to the star, moving in the same plane under their mutual gravitational attraction.

Mechanical planetary compensating drive system [PDF]
, 1973 Drive enables two concentric output shafts to be controlled independently or rotated as a unit. Possible uses are pointing and tracking devices, rotary camera shutters with variable light control, gimbal systems with yaw and pitch movement, spectrometer ...

Dynamical Measurements of the Interior Structure of Exoplanets [PDF]
, 2013 Giant gaseous planets often reside on orbits in sufficient proximity to their host stars for the planetary quadrupole gravitational field to become non-negligible. In presence of an additional planetary companion, a precise characterization of the system'

On the HU Aquarii planetary system hypothesis
, 2012 In this work, we investigate the eclipse timing of the polar binary HU Aquarii that has been observed for almost two decades. Recently, Qian et al. attributed large (O-C) deviations between the eclipse ephemeris and observations to a compact system of ...

On the sensitivity of extrasolar mass-loss rate ranges: HD 209458b a case study [PDF]
, 2013 We present a 3D hydrodynamic study of the effects that different stellar wind conditions and planetary wind structures have on the calculated Ly-$\alpha$ absorptions produced during the transit of HD 209458b.

Equilibria in the secular, non-coplanar two-planet problem
, 2009 We investigate the secular dynamics of a planetary system composed of the parent star and two massive planets in mutually inclined orbits. The dynamics are investigated in wide ranges of semi-major axes ratios (0.1-0.667), and planetary masses ratios (0 ...
