Understanding the variability of helium abundance in the solar corona using three-fluid modeling and UV observations
Leon Ofman, Yogesh, Silvio Giordano
The variability of helium abundance in the solar corona and the solar wind is an important signature of solar activity, solar cycle, solar wind sources, as well as coronal heating…
Contribution of polar plumes to fast solar wind
L. Zangrilli, S. M. Giordano
Context. Several physical properties of solar polar plumes have been identified by different published studies, however such studies are rare and sometimes in disagreement. Aims. T…
Probing the Solar Wind Acceleration Region with the Sun--Grazing Comet C/2002 S2
Silvio Giordano, John C. Raymond, Philippe Lamy +2
Comet C/2002 S2, a member of the Kreutz family of Sungrazing comets, was discovered in white light images of the SOHO/LASCO coronagraph on 2002 September 18 and observed in \hi\, \…
UVCS/SoHO Catalog of Coronal Mass Ejections from 1996 to 2005: Spectroscopic Proprieties
Silvio Giordano, Angela Ciaravella, John Raymond +2
Ultraviolet spectra of the extended solar corona have been routinely obtained by SoHO/UVCS since 1996. Sudden variations of spectral parameters are mainly due to the detection of C…
Bright Ray-like Features in the Aftermath of CMEs: White Light vs UV Spectra
A. Ciaravella, D. F. Webb, S. Giordano +1
Current sheets are important signatures of magnetic reconnection in the eruption of confined solar magnetic structures. Models of Coronal Mass Ejections (CMEs) involve formation of…
Observations and models of slow solar wind with Mg9+ ions in quiescent streamers
Leon Ofman, Lucia Abbo, Silvio Giordano
Quiescent streamers are characterized by a peculiar UV signature as pointed out by the results from the observations of the Ultraviolet and Coronograph Spectrometer (UVCS) on board…
Morphology, dynamics and plasma parameters of plumes and inter-plume regions in solar coronal holes
K. Wilhelm, L. Abbo, F. Auchere +12
Coronal plumes, which extend from solar coronal holes (CH) into the high corona and - possibly - into the solar wind (SW), can now continuously be studied with modern telescopes an…
