Exterior orientation of CBERS-2B imagery using multi-feature control and orbital data
(2013-05-01)
The major contribution of this paper relates to the practical advantages of combining Ground Control Points (GCPs), Ground Control Lines (GCLs) and orbital data to estimate the exterior orientation parameters of images ...

Breaking the chains: Hot super-Earth systems from migration and disruption of compact resonant chains
(2017-09-11)
'Hot super-Earths' (or 'mini-Neptunes') between one and four times Earth's size with period shorter than 100 d orbit 30-50 per cent of Sun-like stars. Their orbital configuration - measured as the period ratio distribution ...
On the mass determination of super-Earths orbiting active stars: the CoRoT-7 system
(EDP SCIENCES S A, 2011)
Context. Star activity makes the mass determination of CoRoT-7b and CoRoT 7c uncertain. Investigators of the CoRoT team proposed several solutions, but all but one of them are larger than the initial determinations of 4.8 ...
Rocky super-Earths or waterworlds: The interplay of planet migration, pebble accretion, and disc evolution
(2019-04-01)
Recent observations have found a valley in the size distribution of close-in super-Earths that is interpreted as a signpost that close-in super-Earths are mostly rocky in composition. However, new models predict that ...
