High-Rate Altimetry in SNR-Based GNSS-R: Proof-of-Concept of a Synthetic Vertical Array
(2021-01-01)
Global Navigation Satellite System Reflectometry (GNSS-R) has emerged as a promising remote sensing technique for coastal sea level monitoring. GNSS-R based on signal-to-noise ratio (SNR) observations employs a single ...
Effects of the planetary migration on some primordial satellites of the outer planets
(Edp Sciences S A, 2011-12-01)
Context. During the first hundred million years after the formation of our solar system, the four giant planets are believed to have migrated significantly (by up approximate to 20 AU). The current scenario and dynamics ...
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 ...
Cratering and age of the small Saturnian satellites
(EDP Sciences, 2019-04-25)
Context. The small (=135 km mean radius) satellites of Saturn are closely related to its rings and together they constitute a complex dynamical system where formation and destruction mechanisms compete against each other. ...
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 ...
Genomic organization and transcription analysis of the 195-bp satellite DNA in Trypanosoma cruzi
(ELSEVIER SCIENCE BV, 2008)
The 195-bp satellite DNA is the most abundant Trypanosoma cruzi repetitive sequence. Here we show by RNA blotting and RT-PCR that 195 SAT is intensely transcribed. We observed a positive correlation between the level of ...

Formation of short-period planets by disc migration
(2019-01-01)
Protoplanetary discs are thought to be truncated at orbital periods of around 10 d. Therefore, the origin of rocky short-period planets with P < 10 d is a puzzle. We propose that many of these planets may form through the ...
