1. Signatures of two distinct driving mechanisms in the evolution of coronal mass ejections in the lower corona / Assinaturas de dois mecanismos distintos na evolução de ejeções de massa coronal na baixa coroa
As ejeções de massa coronal (coronal mass ejections - CMEs) são as maiores causadoras das perturbações do clima espacial. Seus mecanismos físicos e sua influência no ambiente geoespacial são foco importante em debates e pesquisas. Nosso objetivo é compreender como a configuraçãoo magnética inicial da CME afeta sua evolução na baixa coroa, até

2. Signatures of two distinct driving mechanisms in the evolution of coronal mass ejections in the lower corona / Assinaturas de dois mecanismos distintos na evolução de ejeções de massa coronal na baixa coroa
Coronal mass ejections (CMEs) are the major driver for space weather disturbances. Their physical mechanisms and their influence on the geospace environment are the subject of active research and debate. Our goal is to understand how the initial magnetic configuration of a CME affects its evolution through the lower corona, until 6R⊙. We compare ou

3. Bidimensional hidrodinamic model of coronal mass ejections / Modelo hidrodinâmico bidimensional de ejeção de massa coronal
A twodimensional hydrodynamical model is used to follow, in time and space, coronal structures that propagate through the interplanetary medium. These estructures are known as Coronal Mass Ejections (CMEs). A twodimensional grid with the steady state solar wind solution representing the inteplanetary medium is used as the initial condition. The steady state

4. Estudo de estruturas geoefetivas no meio interplanetário e de suas causas solares. / Study of the interplanetary geoeffective structures and their solar origins
In this work we have studied geoeffective interplanetary structures observed near earth and their solar origins, involving several basic and applied scientific aspects, related to the research area named Space Weather. We present a study of the coronal mass ejections (CME) observed at the sun by the LASCO instrument, in the period of January 1997 to April 20
