Potential Biases in the Detection of Planetary Systems with Large Transit Timing Variations
methods: data analysis – planetary systems – planets and satellites: detection –techniques: photometric
2011/9/29
The Transit Timing Variations (TTVs) technique provides a powerful tool to detect additional planets in transiting exoplanetary systems. In this paper we show how transiting planets with significant T...

Large hydrogen-isotopic (D/H) fractionations between lipids and
growth water have been observed in most organisms studied to
date. These fractionations are generally attributed to isotope
effects i...
