  2. 1. There and back again... An Earth magneto-tale : understanding plasma flows in the magnetotail

    Author : Alexandre De Spiegeleer; Maria Hamrin; Herbert Gunell; Timo Pitkänen; Colin Forsyth; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma dynamics; Earth magnetosphere; magnetotail; plasma sheet flows; oscillatory flows; burst bulk flows; tailward flows; rymdfysik; Space Physics; rymd- och plasmafysik; Space and Plasma Physics;

    Abstract : On average, the Earth's magnetotail plasma sheet seems to be a calm region of the magnetosphere where the plasma moves slowly towards Earth. However, the plasma sheet actually hosts many phenomena, some of which can affect Earth. READ MORE

  4. 2. The solar wind protons inside the induced magnetosphere of Mars

    Author : Catherine Dieval; Maria Hamrin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Abstract : Mars is an unmagnetized planet. Mars has no intrinsic magnetic field but has local magnetic anomalies in the crust. The solar wind, which is the plasma flowing from the Sun at supersonic speed, interacts with the magnetic fields of the currents induced in the conductive Martian ionosphere, deviates and slows down to subsonic speeds.

    Abstract : The present-day Venusian atmosphere is crushingly dense, extremely hot and arid. Yet, in its early history, Venus presumably had a massive amount of water, which, if spread evenly over the surface, provided a water depth of 10s to 100s of meters. Therefore, over the course of the atmospheric evolution, the water must have been removed from Venus. READ MORE
