Development of a formalism for computing transits of Earth-directed CMEs, plasma sheaths, and shocks. Towards a forecasting tool
(ELSEVIER LTD, 2016-11-15)
Interplanetary Coronal mass ejections (ICMEs) (super-magnetosonically) faster than the ambient solar wind are preceded by shock waves. Earth-directed shock waves, plasma sheaths and ICMEs are precursors of the major ...
Periodicidades no fluxo de raios cósmicos e análise de choques interplanetários
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2010-01-08)
Muons and neutrons that reach the Earth surface with high energy constitute a particles’ group called secondary cosmic rays. In order to study the flux of this particles data from muons and neutrons stations are used. The ...

Characterization of CME-driven shock in the interplanetary medium using type II radio bursts
(2017-11)
Type II radio bursts are indirect signatures of the fast magnetosonic shock formation in the heliosphere. Those types of MHD shocks accelerate electron beams that via plasma emission mechanism produce electromagnetic ...
The ULF wave foreshock boundary: Cluster observations
(American Geophysical Union, 2015-06-01)
The interaction of backstreaming ions with the incoming solar wind in the upstream region of the bow shock gives rise to a number of plasma instabilities from which ultralow frequency (ULF) waves can grow. Because of their ...
Análisis de ondas de ultra-baja frecuencia en la zona anterior al choque de SaturnoULF waves analysis in Saturn’s foreshock
(Asociación Física Argentina, 2012-08)
A través del estudio de los datos provistos por el magnetómetro VHM, a bordo de la sonda espacial Cassini-Huygens en órbita alrededor del planeta desde el año 2004, realizamos un relevamiento y análisis detallados de las ...
Proton cyclotron waves upstream from Mars: Observations from Mars Global Surveyor
(Elsevier, 2013-02)
We present a study on the properties of electromagnetic plasma waves in the region upstream of the Martian bow shock, detected by the magnetometer and electron reflectometer (MAG / ER) onboard the Mars Global Surveyor (MGS) ...
