A Point-Spread Function for the Extreme Ultraviolet High-Resolution Imager on board Solar Orbiter

Stefan J. Hofmeister, Emil Kraaikamp, Sergei Shestov +7

We present the point-spread function (PSF) of the Extreme Ultraviolet High-Resolution Imager (HRIEUV) onboard Solar Orbiter, which observes the Sun at 174 Angstrom. This PSF provid…

Theoretical Ion Sputtering Yields from Loose Powders using a Multiscale Monte Carlo Approach

Sebastien Verkercke, Deborah Berhanu, Caixia Bu +5

Ion sputtering from loose powders remains poorly understood despite its relevance to planetary science and industry. We developed a multiscale Monte Carlo model to simulate sputter…

Observations of Non-thermal Velocity and Comparison with Alfvén Wave Turbulence Model in Solar Active Regions

M. Asgari-Targhi, D. H. Brooks, M. Hahn +3

We present a study of spectral line width measurements from the Extreme Ultraviolet Imaging Spectrometer (EIS) on {\it Hinode}. We used spectral line profiles of Fe {\sc xvi} 262.9…

Recommended Thermal Rate Coefficients for the C + H Reaction and Some Astrochemical Implications

S. Vissapragada, C. F. Buzard, K. A. Miller +4

We have incorporated our experimentally derived thermal rate coefficients for C + H forming CH and CH into a commonly used astrochemical model. We find that the Arr…

Merged-beams Reaction Studies of O + H_3^+

N. de Ruette, K. A. Miller, A. P. O'Connor +4

We have measured the reaction of O + H3+ forming OH+ and H2O+. This is one of the key gas-phase astrochemical processes initiating the formation of water molecules in dense molecul…

Relative Abundance Measurements in Plumes and Interplumes

Chloé Guennou, Michael Hahn, Daniel Wolf Savin

We present measurements of relative elemental abundances in plumes and interplumes. Plumes are bright, narrow structures in coronal holes that extend along open magnetic field line…
