Initial Observations of Interplanetary Shocks by STEREO
Initial observations by the magnetometer on the twin STEREO spacecraft reveal much about shock structure and evolution in the solar wind. Alignments of STEREO with Venus Express reveal that none of the shocks associated with stream interactions and observed with the STEREO spacecraft at 1 AU were present in the solar wind at 0.7 AU, indicating that the region between Venus and Earth is an incub...
متن کاملSpace weather and interplanetary shocks
São discutidos nesse artigo alguns conceitos básicos relacionados ao clima espacial no ambiente próximo da Terra. Devido ao desenvolvimento tecnológico dos anos recentes, o clima espacial tornou-se um tema importante de pesquisa. Os avanços da área se devem principalmente à sua aplicabilidade nos sistemas tecnológicos tanto no espaço próximo quanto na superf́ıcie da Terra. Dentre os diversos tem...
متن کاملParticle Acceleration at Interplanetary Shocks
The acceleration of interstellar pick-up ions as well as solar wind species has been observed at a multitude of interplanetary (IP) shocks by different spacecraft. The efficiency of injection of the pick-up ion component differs from that of the solar wind, and is strongly enhanced at highly oblique and quasi-perpendicular shock events. This paper expands upon previous work modeling the phase s...
متن کاملEvolution of Coronal MHD Shocks into Interplanetary MHD Shocks
One of the fimdamental potential hazards to the “Fire” mission (Solar Probe) is the energetic particle environment near the sun. Heras et al., (1995), Sanahuja el al. (1995), and Sanahuja and Lario (1995) have modeled shock acceleration of low energy particles (< 2 MeV) due to fast ejects from the sun, One c@ical problem in this model, at the present time, is that no one has modeled coronal and...
متن کاملDiffusive Acceleration of Ions at Interplanetary Shocks
Heliospheric shocks are excellent systems for testing theories of particle acceleration in their environs. These generally fall into two classes: (1) interplanetary shocks that are linear in their ion acceleration characteristics, with the non-thermal ions serving as test particles, and (2) non-linear systems such as the Earth’s bow shock and the solar wind termination shock, where the accelera...
