In this work we find the shape and dimension of the solar wind transition surfaces, namely the slow (sonic), the fast magnetosonic and the Alfvén surface, as a function of heliospheric latitude using actual experimental data from Ulysses spacecraft during its first pole to pole journey. We also give the temporal variation of the radius of these surfaces using measurements from spacecraft at 1 A...

[1] Variations in the speed and elemental and ionic charge composition of the solar wind are reported throughout the solar cycle, as observed by the SWICS instrument on Ulysses. The apparent bimodal nature of the solar wind during the solar minimum does not persist throughout the solar cycle. Rather, with increasing solar activity, a continuum of solar wind speeds and charge states is observed....

Aims. By reevaluating a 13-month stretch of Ulysses SWICS H pickup ion measurements near 5 AU close to the ecliptic right after the previous solar minimum, this paper presents a determination of the neutral interstellar H density at the solar wind termination shock and implications for the density and ionization degree of hydrogen in the LIC. Methods. The density of neutral interstellar hydroge...

La Mirada de Ulises es una película 1995 dirigida por Theo Angelopoulos. En ella, el director griego nos invita a seguir los pasos A. un ¿ficticio? cineasta que busca unas bobinas sin procesar Hermanos Manakis. A pesar la simple premisa, pronto descubrimos cómo se convierte en ejercicio profundamente autoconsciente tintes antropológicos y filosóficos sobre cuestiones como identidad, memoria o s...
