For most people, the night sky conjures a sense of stillness, an occasional shooting star the only visible movement. A conversation with Rishabh Datta, however, unveils the supersonic drama crashing a...
Determining the wavelength of Langmuir wave packets at the Earth's bow shock
wavelength Langmuir wave packets Earth's bow shock
2011/8/5
Abstract: The propagation of Langmuir waves in plasmas is known to be sensitive to density fluctuations. Such fluctuations may lead to the coexistence of wave pairs that have almost opposite wave-numb...
Prospects for Detection of Exoplanet Magnetic Fields Through Bow-Shock Observations During Transits
planet-star interactions planets and satellites magnetic fields—stars
2010/11/16
An asymmetry between the ingress and egress times was observed in the near-UV light curve
of the transit planet WASP-12b. Such asymmetry led us to suggest that the early ingress in
the UV light curv...
Nonlinear wave-particle interaction upstream from the Earth's bow shock
Nonlinear wave-particle interaction upstream Earth's bow shock
2009/11/13
Well-defined ring-like backstreaming ion distributions have been recently reported from observations made by the 3DP/PESA-High analyzer onboard the WIND spacecraft in the Earth's foreshock at large di...
Jump conditions for pressure anisotropy and comparison with the Earth's bow shock
Jump conditions pressure anisotropy Earth's bow shock
2009/11/12
Taking into account the pressure anisotropy in the solar wind, we study the magnetic field and plasma parameters downstream of a fast shock, as functions of upstream parameters and downstream pressure...
Large amplitude solitary waves in and near the Earth’s magnetosphere,magnetopause and bow shock:Polar and Cluster observations
Large amplitude solitary waves Earth’s magnetosphere magnetopause bow shock
2009/11/11
Solitary waves with large electric fields (up to 100's of mV/m) have been observed throughout the magnetosphere and in the bow shock. We discuss observations by Polar at high altitudes ( ~ 4-8 RE ), d...
Comment on "MeV magnetosheath ions energized at the bow shock" by S.-W. Chang et al
Storm events ion the bow shock energy as much as magnetic sheath measuring magnetic sheath the bow shock
2017/3/23
From a study of the 4 May 1998 storm event, Chang et al. [2001] (hereinafter referred to as CETAL01) suggested that "ions are accelerated at the quasi-parallel bow shock to energies as high as 1 MeVan...
