Evidence for Solar-Wind Charge-Exchange X-Ray Emission from the Earth’s Magnetosheath
We report an apparent detection of the CVI 4p to 1s transition line at 459 eV, during a long-term enhancement (LTE) in the Suzaku north ecliptic pole (NEP) observation of 2005 September 2. The observed intensity of the line is comparable to that of the CVI 2p to 1s line at 367 eV. This is strong evidence for the charge-exchange process. In addition to the CVI lines, emission lines from OVII, OV...
متن کاملRevising the Local Bubble Model due to Solar Wind Charge Exchange X-ray Emission
The hot Local Bubble surrounding the solar neighborhood has been primarily studied through observations of its soft X-ray emission. The measurements were obtained by attributing all of the observed local soft X-rays to the bubble. However, mounting evidence shows that the heliosphere also produces diffuse X-rays. The source is solar wind ions that have received an electron from another atom. Th...
متن کاملXMM-Newton Observation of Solar Wind Charge Exchange Emission
We present an XMM-Newton spectrum of diffuse X-ray emission from within the solar system. The spectrum is dominated by probable C VI lines at 0.37 keV and 0.46 keV, an O VII line at 0.56 keV, O VIII lines at 0.65 keV and ∼ 0.8 keV, Ne IX lines at ∼ 0.92 keV, and Mg XI lines at ∼ 1.35 keV. This spectrum is consistent with that expected from charge exchange emission between the highly ionized sol...
متن کاملSolar wind charge exchange and local hot bubble X-ray emission with the DXL sounding rocket experiment
The Diffuse X-ray emission from the Local Galaxy (DXL) sounding rocket is a NASA approved mission with a scheduled first launch in December 2012. Its goal is to identify and separate the X-ray emission of the solar wind charge exchange (SWCX) from that of the local hot bubble (LHB) to improve our understanding of both. To separate the SWCX contribution from the LHB, DXL will use the SWCX signat...
متن کاملHard X – ray emission from the solar
This review surveys hard X-ray emissions of non-thermal electrons in the solar corona. These electrons originate in flares and flare-related processes. Hard X-ray emission is the most direct diagnostic of electron presence in the corona, and such observations provide quantitative determinations of the total energy in the non-thermal electrons. The most intense flare emissions are generally obse...
