On the size of the cometary tail magnetic field
Ershkovich has recently criticized earlier arguments by Mendis for substantial magnetic fields (B"" 1001) in the cometary plasma tail. It is shown that these criticisms are unjustified. Contrary to Ershkovich's claim, it is shown that the folding rate of the tail rays is indeed indicative of a substantial tail magnetic field. Much of the disagreement stems from Ershkovich's idealization of the ...
متن کاملA global model of cometary tail disconnection events triggered by solar wind magnetic variations
[1] Presented in this paper are the results of a time-dependent, fully three-dimensional self-consistent ideal magneto-hydrodynamics (MHD) model of disconnection events (DEs) in the cometary plasma tail. Understanding the interaction of cometary plasma with the solar wind is a very important problem in space plasma physics. This study focuses on the detailed MHD processes which occur during DEs...
متن کاملAMIRAS - An Airborne MIRAS Demonstrator
This paper describes AMIRAS, an airborne demonstrator of the Microwave Imaging Radiometer with Aperture Synthesis, which is the instrument onboard ESA’s Soil Moisture and Ocean Salinity (SMOS) mission. The main electrical, mechanical, thermal, and control elements of the demonstrator are shown, together with its capabilities and performances as demonstrator of the spaceborne instrument. AMIRAS ...
متن کاملCometary Diversity and Cometary Families 1.1 Introduction
Comets are classified from their orbital characteristics into two separate classes: nearly-isotropic, mainly long-period comets and ecliptic, short-period comets. Members from the former class are coming from the Oort cloud. Those of the latter class were first believed to have migrated from the Kuiper belt where they could have been accreted in situ, but recent orbital evolution simulations sh...
متن کاملThe MIRAS "all-licef" calibration mode
After more than six years of operation, the SMOS (Soil Moisture and Ocean Salinity) European Space Agency (ESA) mission [1] has proven to be highly useful for a variety of scientific applications related to soil moisture over land, ocean salinity and winds over ocean and specific studies over ice covered surfaces. Level 2 data is currently used by many institutions around the world to extract r...
