Scientific Sessions

  • Ionosphere: Earth and Other Planets
    Chair: Dr. Paulo Alexandre Bronzato Nogueira (IFSP)
    Co-Chairs: Dr. Fabiano da Silveira Rodrigues (The University of Texas at Dallas) and Dra. Laysa Cristina Araújo Resende (INPE)

    This session invites general contributions concerning all the processes controlling ionospheric phenomena on Earth and other planets. We welcome observational, modeling and numerical simulation studies that advance our understanding on the ionospheric behaviors. Particularly encouraged are contributions on terrestrial ionosphere addressing investigations of ionospheric response to geomagnetic storms and substorms, precipitation of energetic particles into the lower ionosphere, latitudinal and longitudinal variations of ionospheric electrodynamics, climatological studies, sporadic-E layers, E- and F-region ionospheric irregularities, ionospheric scintillation and its effects on communication and navigation systems, total electron content variability, as well as the neutral atmosphere-ionosphere coupling such as the travelling ionospheric disturbances, planetary wave and tide signatures. We also seek presentations addressing multiple-sensor instruments and measurements, and others that combine ground-based and space-based techniques, including CubeSats. 
     


    Physics and Chemistry of the Neutral Atmosphere
    Chair: Dr. José Valentin Bageston (CRS/INPE)
    Co-Chairs: Dr. Pierre-Dominique Pautet (Utah State University) and Dr. Mauricio José Alves Bolzam (UFG)

    This session invites presentations relating to the physics and chemistry of the troposphere, stratosphere, mesosphere and thermosphere. We welcome contributions addressing recent progress regarding phenomena occurring from the lower to the upper neutral atmosphere. This session will also include papers dealing with different techniques and instruments (ground- and space-based) used for measurements of neutral winds, temperature, chemical composition and airglow, as well as theoretical and computational modeling. Research results addressing the coupling processes in the atmosphere-ionosphere system are encouraged, as well as contributions involving the following topics: energy and momentum transport by gravity waves, tides and planetary waves; interaction between atmospheric waves; secondary waves generation; long-term variations in the stratosphere-mesosphere-thermosphere system; energetic particle precipitation affecting the mesosphere and stratosphere; sudden stratospheric warming and transient luminous events. Research topics involving the areas and sub-areas of meteorology and earth system science are also welcome. 
     


    Space Weather and Sun-Earth Connections
    Chair: Dr. Alisson Dal Lago (INPE)
    Co-Chairs: Dr. José Henrique Fernandez (UFRN) and Dr. Clezio Marcos De Nardin (INPE)

    Space weather is a multidisciplinary subject covering both theoretical and applied research. This theme is focused on the monitoring of solar variability and the space environment close to the Earth that can influence the functioning of geospatial technological systems, and affect human life and health. This session seeks presentations addressing studies on the solar activity, heliosphere, cosmic rays, interplanetary medium, magnetosphere, ionosphere, neutral atmosphere, as well as magnetotelluric research. We also welcome general contributions about the various physical processes and geomagnetic phenomena related to both, external and/or internal origin contributions to the geomagnetic field, including modeling, numerical simulation and observational studies. 



    Physics of Plasmas
    Chair: Rodrigo Andres Miranda Cerda (UNB)
    Co-Chairs: Dr. Pablo Rubén Muñoz Gutberlet (Universidad de La Serena) and Dr. Marco Antônio Ramirez Ramos (UNIVAP)

    This session will be accepting theoretical and experimental works on plasma physics. Contributions on astrophysical and space plasmas are especially welcomed, as well as plasma studies on thermonuclear fusion and material sciences. Results on plasma waves and instabilities, chaos and non-linear phenomena, turbulence, plasmas in magnetic confinement, high-density plasmas, MHD and PIC numerical simulations and non-collisional plasmas are strongly encouraged. This session also welcomes contributions on instrumentation and measurement techniques in laboratory plasmas (tokamaks and stellarators) and in-situ measurements in space plasmas. Contributions on technological applications of plasmas such as plasma assisted combustion, material treatment (microelectronics, aerospace, energy and biomedicine), nanotechnology and electric propulsion are also strongly encouraged. 



    Solar Physics, Interplanetary Medium and Planetary Magnetospheres
    Chair: Dr. Jean-Pierre Raulin (UPM)
    Co-Chairs: Dr. Jean Carlo Santos (UTFPR) and Dr. Marcos Vinicius Dias Silveira (GSFC/NASA and Catholic University of America)

    This session is about solar activity phenomena and their influence on the dynamics of the interplanetary medium and on planetary magnetospheres. This session invites observational or theoretical works, including approaches addressing modeling and simulations of transient or long-term solar activity, solar wind phenomena, the generation and origin of impulsive events, such as solar flares and coronal mass ejections (CME), particle acceleration, and solar emissions at different bands of the electromagnetic spectrum. In addition, we also welcome contributions dealing with the role of the solar magnetic field in the different processes and quiescent or transient phenomena, and its interaction with planetary magnetic fields once the solar magnetic field extends throughout the interplanetary space. 



    Astronomy and Astrophysics
    Chair: Dr. Alexandre Soares de Oliveira (UNIVAP)
    Co-Chairs: Dra. Ângela Cristina Krabbe (UNIVAP) and Dr. Irapuan Rodrigues de Oliveira Filho (UNIVAP)

    The Brazilian astronomy is booming, driven by factors such as the use of large modern telescopes, the growing involvement of the astronomical community in the development of cutting-edge scientific instrumentation, and the emerging of new graduate programs. This is all happening as the new generation of giant telescopes is under construction, with effective Brazilian participation. This session aims to provide a moment of exchange of scientific ideas, as well as foster professional and social contacts. Participants will have the opportunity to publicize and discuss their work for a multidisciplinary audience that covers all areas of astronomy research in Brazil, as well as to attend invited conferences given by experts in different areas of research.
