Identifying Inflated Super-Earths and Photo-evaporated Cores
(2018-10-20)
We present empirical evidence, supported by a planet formation model, to show that the curve approximates the location of the so-called photo-evaporation valley. Planets below that curve are likely to have experienced ...
MUX multispectral imager for CBERS 3&4 satellite series
(2015-11-20)
China-Brazil Earth Resources Satellites (CBERS) program is a partnership agreement established in 1988 between Brazil and China for the development and operation of Earth observation satellites. The first satellite series, ...
Analysis of communication strategies for earth observation satellite constellations
(Institute of Electrical and Electronics Engineers, 2016-06)
Earth observation satellite constellations are arising as a new paradigm with important advantages in comparison with traditional monolithic systems. In particular, the concept of Segmented Architecture proposes to transform ...

Formation of planetary systems by pebble accretion and migration: Hot super-Earth systems from breaking compact resonant chains
(2021-06-01)
At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii and orbital periods of less than 100 days.We use N-body simulations including a model for gas-assisted pebble accretion and disk–planet ...
Low-cost and portable ground station for the reception of NOAA satellite images
(Science and Information Organization, 2019)
Currently, in Peru, the study of satellite images is increasing because it has the Earth observation satellite PeruSat-1. However, the cost of implementing a ground station is very high; for this reason, it is baffling ...
Earth as art.
(Washington DC, 2010)
In 1960, the United States put its first Earth-observing environmental satellite into orbit around the planet. Over the decades, these satellites have provided invaluable information, and the vantage point of space has ...
