Speaker: Erico L. Rempel Affiliation: Department of Mathematics, ITA and DGE/INPE Date: April 15, 2026, at 2 PM Location: Barclay Clemesha Auditorium, CEA II building, at INPE headquarters in São José dos Campos (Av. dos Astronautas, 1758, Jardim da Granja) Title: LAGRANGIAN COHERENT STRUCTURES IN SPACE PLASMAS Abstract: Space plasmas can be described as turbulent conductive flows, where the fluid motion is determined by a series of coherent kinetic and magnetic structures of different types. Identifying and monitoring the evolution of these structures is crucial for a deep understanding and, possibly, for predicting plasma behavior. Lagrangian coherent structures constitute a recently developed theory to describe the transport of materials in fluids, with carefully crafted mathematical approaches to detect the main transport barriers responsible for controlling fluid flows. In this work, we review the application of this theory to space plasmas using numerical simulations and satellite observations. In particular, the results show that Lagrangian coherent structures can be used to better understand complex plasma phenomena in the solar atmosphere. |

Speaker: Prof. Dr. Walmir Thomazzi Cardoso (UFRJ) Date: April 8, 2026 Location: Barclay Clemesha Auditorium, CEA II building, INPE headquarters in São José dos Campos (Av. dos Astronautas, 1758, Jardim da Granja) Seminar Title: We are under many skies: Cultural Astronomy as a field of academic research. Abstract: Where we see a scorpion in the sky, the Tukano indigenous people of the Upper Rio Negro see a jararaca snake, and some Guarani villages see part of the body of a rhea. Beyond distinct arrangements and designs in the sky, these representations reveal part of the complex relationships existing in each culture, including their conceptions of the natural world. In times of global climate change, what can we learn from the sky-earth relationships locally established by human groups? |

Speaker: Walter D. Gonzalez Affiliation: National Institute for Space Research (INPE) Date: March 11, 2026 at 10am Location: Barclay Clemesha Auditorium, CEA II building, INPE headquarters in São José dos Campos (Av. dos Astronautas, 1758, Jardim da Granja) Title: SMILE Mission Abstract: The SMILE (Solar Wind - Magnetosphere - Ionosphere Link Explorer) mission, from ESA (European Space Agency) and CAS (Chinese Academy of Sciences), expected to launch in April 2026 (and be placed in an elliptical orbit with an apogee of 30 Earth radii and inclined relative to the ecliptic), aims to monitor fundamental aspects of the interaction of the solar wind with the Earth's magnetosphere, using sensors to measure plasma and interplanetary magnetic field, X-ray emission from the magnetosheath and the The study will explore the magnetopause, as well as UV emission from the auroral region. These measurements are expected to provide a better understanding of global aspects of the magnetopause and the auroral region, particularly during periods of intense geomagnetic storms and sub-storms.
