The Solar Wind Charge-eXchange contribution to the Local Soft X-ray Background. Model to data comparison in the 0.1-1.0 keV band
Dimitra Koutroumpa, Rosine Lallement, Vasili Kharchenko +1
The major sources of the Soft X-ray Background (SXRB), besides distinct structures as supernovae and superbubbles (e.g. Loop I), are: (i) an absorbed extragalactic emission followi…
Exploring Interstellar Titanium and Deuterium Abundances and Other Correlations
R. Lallement, G. Hebrard, B. Y. Welsh
The origin of the observed variability of the gas-phase D/H ratio in the local interstellar medium is still debated, and in particular the role of deuterium depletion onto dust gra…
OVII and OVIII line emission in the diffuse soft X-ray background: heliospheric and galactic contributions
D. Koutroumpa, F. Acero, R. Lallement +2
We study the 0.57 keV (O VII triplet) and 0.65 keV (O VIII) diffuse emission generated by charge transfer collisions between solar wind (SW) oxygen ions and interstellar H and He n…
Velocity Profiles in the Solar Corona from Multi-Instrument Observations
E. Quemerais, R. Lallement, D. Koutroumpa +1
We present a method to derive outflow velocities in the solar corona using different data sets including solar wind mass flux coming from the SWAN/SOHO instrument, electron density…
Interplanetary Lyman line profiles: variations with solar activity cycle
Eric Quémerais, Rosine Lallement, Jean-Loup Bertaux +4
Interplanetary Lyman alpha line profiles are derived from the SWAN H cell data measurements. The measurements cover a 6-year period from solar minimum (1996) to after the solar max…
Heliospheric and Astrospheric Hydrogen Absorption towards Sirius: No Need for Interstellar Hot Gas
V. V. Izmodenov, R. Lallement, Y. G. Malama
We use an updated self-consistent kinetic/gasdynamic model of the solar wind/interstellar flow interaction to compute the Lyman-alpha absorption by hydrogen atoms of both interstel…
