Stability of the interstellar hydrogen inflow longitude from 20 years of SOHO/SWAN observations
Dimitra Koutroumpa, Eric Quémerais, Olga Katushkina +3
Aims. A recent debate on the decade-long stability of the interstellar He flow vector, and in particular the flow longitude, has prompted us to check for any variability in the int…
Electrical properties and porosity of the first meter of the nucleus of 67P/Churyumov-Gerasimenko. As constrained by the Permittivity Probe SESAME-PP/Philae/Rosetta
Anthony Lethuillier, Alice Le Gall, Michel Hamelin +7
Context. Comets are primitive objects, remnants of the volatile-rich planetesimals from which the solar system condensed. Knowing their structure and composition is thus crucial fo…
The Interstellar H Flow: Updated Analysis of SOHO/SWAN Data
Rosine Lallement, Eric Quémerais, Dimitra Koutroumpa +3
We update two kinds of results obtained with the SWAN instrument on board SOHO. First, we use H cell data recorded in 2001 and derive the H flow direction in the same way we perfor…
The solar wind as seen by SOHO/SWAN since 1996: comparison with SOHO/LASCO C2 coronal densities
Rosine Lallement, Eric Quemerais, Philippe Lamy +3
We update the SOHO/SWAN H Lyman-alpha brightness analysis to cover the 1996-2008 time interval. A forward model applied to the intensity maps provides the latitude and time depende…
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…
