Hector Perez-De-Tejada

National Autonomous University of Mexico Mexico

Professor Héctor Pérez-de-Tejada obtained a bachelor’s degree in science from the National Autonomous University of Mexico (UNAM) and later received his PhD degree from the University of Colorado (Boulder, Colorado). He has been a full researcher at the Institute of Geophysics of UNAM and participated in various academic functions first at the Ensenada (Baja California) campus and later at the Mexico City campus of that Institution. He was president of the Mexican Geophysical Union and has been a fellow of the National Research System in Mexico (level 3). Currently, he is the head of the Space Science Department of the Institute of Geophysics of UNAM, has participated in numerous research projects including as a guest investigator of the Pioneer Venus Orbiter mission of NASA at Venus, and has been involved in the analysis of plasma data of the Mars and Venus Express spacecraft of ESA. His academic activities have been related to studies of the interaction of the solar wind with planetary ionospheres and he has participated in many scientific publications where he has been the main author in most of them. He has been responsible for activities in the ionospheric sounder station near Mexico City and has been the supervisor of many graduate students at the Ensenada and at the Mexico City campuses of UNAM.

Latest work with IntechOpen by Hector Perez-De-Tejada

The contents of the book cover a wide variety of topics related to the analysis of the dynamics of vortices and describe the results of experiments, computational modeling and their interpretation. The book contains 13 chapters reaching areas of physics in vortex dynamics and optical vortices including vortices in superfluid atomic gases, vortex laser beams, vortex-antivortex in ferromagnetic hybrids, and optical vortices illumination in chiral nanostructures. Also, discussions are presented on particle motion in vortex flows, on the simulation of vortex-dominated flows, on vortices in saturable media, on achromatic vortices, and on ultraviolet vortices. Fractal light vortices, coherent vortex beams, together with vortices in electric dipole radiation, and spin wave dynamics in magnetic vortices are examined as well.

Vortex Structure in the Plasma Flow Channels of the Venus Wake

By Héctor Pérez-de-Tejada, Rickard Lundin and Devrie S. Intriligator

An overall description of the solar wind that streams into the Venus wake and the ionospheric plasma that is driven from that planet’s magnetic polar region is examined from measurements conducted with the various spacecraft that have probed the Venus plasma environment (Mariner 5, Venera 9-10, Pioneer Venus Orbiter, Venus Express). It is shown that the plasma properties in the Venus wake describe conditions that are less suitable for steady gyrotropic trajectories of the planetary particles but require the assumption that they are also subject to a fluid dynamic description that introduces structures similar to those generated through kinetic forces. Most notable is that there is evidence of decelerated solar wind proton fluxes measured within plasma channels that are mostly populated by outflowing planetary ions and that the solar wind particles moving in the wake execute trajectories that resemble motion along a vortex shape with motion directed even back toward the planet in the Venus inner wake. The plasma flow channels are mostly restricted to the vicinity of the midnight plane and extend downstream from the magnetic polar region.
