On the potential energy in a gravitationally bound two-body system with arbitrary mass distribution
K. Wilhelm, B. N. Dwivedi
The potential energy problem in a gravitationally bound two-body system has recently been studied in the framework of a proposed impact model of gravitation \citep{WilDwi}. The res…
Gravitational matter-antimatter impact interactions
K. Wilhelm, B. N. Dwivedi
The production of antihydrogen by several research groups provides the opportunity to measure the gravitational behaviour of antimatter in the gravitational field of the Earth. The…
Sunspot transition region oscillations in NOAA 8156
N. Brynildsen, T. Leifsen, O. Kjeldseth-Moe +2
Based on observations obtained with the Solar and Heliospheric Observatory - SOHO joint observing program for velocity fields in sunspot regions, we have detected 3 min transition…
Stereoscopic Polar Plume Reconstructions from Stereo/Secchi Images
L. Feng, B. Inhester, S. K. Solanki +7
We present stereoscopic reconstructions of the location and inclination of polar plumes of two data sets based on the two simultaneously recorded images taken by the EUVI telescope…
On the potential energy in an electrostatically bound two-body system
K. Wilhelm, B. N. Dwivedi
The potential energy problem in an electrostatically bound two-body system is studied in the framework of a recently proposed impact model of the electrostatic force and in analogy…
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…
