Dynamical stability of the Gliese 581 exoplanetary system [PDF]
, 2014 Using numerical methods we investigate the dynamical stability of the Gliese 581 exoplanetary system. The system is known to harbour four planets (b-e).

Specific Analysis of Web Camera and High Resolution Planetary Imaging [PDF]
Journal of Astronomy and Space Sciences, 2006 Web camera is usually used for video communication between PC, it has small sensing area, cannot using long exposure application, so that is insufficient for astronomical application.

Disc-planet, planet-planet, and star-planet interactions during planet formation
, 2003 In this article we present results from three on-going projects related to the formation of protoplanets in protostellar discs. We present the results of simulations that model the interaction between embedded protoplanets and disc models undergoing MHD turbulence.

EVIDENCE FOR A DISTANT GIANT PLANET IN THE SOLAR SYSTEM [PDF]
, 2016 Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper Belt exhibit an unexpected clustering in their respective arguments of perihelion. While several hypotheses have been put forward to explain this alignment,

Hints for a Turnover at the Snow Line in the Giant Planet Occurrence Rate [PDF]
Astrophysical Journal, 2018 The orbital distribution of giant planets is crucial for understanding how terrestrial planets form and predicting yields of exoplanet surveys. Here, we derive giant planets occurrence rates as a function of orbital period by taking into account the ...

Current Biology, 2005 What makes us humans so special? Our language, our genes, our culture, our cognitive skills? At the Max-Planck-Institute for Evolutionary Anthropology in Leipzig, psychologists, linguists and biologists tackle this old question in a truly multidisciplinary way. Their results have implications not just for our understanding of human evolution--they also

The Orbital Eccentricity of Small Planet Systems [PDF]
Astronomical Journal, 2018 We determine the orbital eccentricities of individual small Kepler planets, through a combination of asteroseismology and transit light-curve analysis.
