Isotopic Composition of Solar Wind Calcium: First in Situ Measurement by CELIAS/MTOF on Board SOHO [PDF]
, 1997 We present first results on the Ca isotopic abundances derived from the high resolution Mass Time-of-Flight (MTOF) spectrometer of the charge, element, and isotope analysis system (CELIAS) experiment on board the Solar and Heliospheric Observatory (SOHO).

Earth, Planets and Space, 2020 The IGRF offers an important incentive for testing algorithms predicting the Earth’s magnetic field changes, known as secular variation (SV), in a 5-year range. Here, we present a SV candidate model for the 13th IGRF that stems from a sequential ensemble

Full-disc Ca ii K observations—A window to past solar magnetism
Frontiers in Astronomy and Space Sciences, 2022 Full-disc observations of the Sun in the Ca ii K line provide one of the longest collections of solar data. First such observations were made in 1892 and since then various sites around the world have carried out regular observations, with Kodaikanal ...

Novel Solar driven Cooling System Integrated with Solar Still System [PDF]
University of the Future: Re-Imagining Research and Higher Education, 2020 Novel integrated solar cooling and solar distillation system is introduced to meet the high cooling and fresh water demands in hot and arid regions such as Qatar. The system is composed of a solardriven ejector cooling system coupled with a single-slope solar still.

Formation and dynamics of a solar eruptive flux tube
Nature Communications, 2018 Solar eruptions are large explosions occurring in the solar atmosphere. Here, the authors perform magnetohydrodynamic simulations to unveil the dynamics of a solar eruption, and find that these are dominated by nonlinear processes involving flux tube ...

A simple stochastic model for dipole moment fluctuations in numerical dynamo simulations
Frontiers in Earth Science, 2016 Earth's axial dipole field changes in a complex fashion on many differenttime scales ranging from less than a year to tens of million years.Documenting, analysing, and replicating this intricate signalis a challenge for data acquisition, theoretical ...

Extra-solar planetary systems [PDF]
Proceedings of the National Academy of Sciences, 1999 The discovery of extra-solar planets has captured the imagination and interest of the public and scientific communities alike, and for the same reasons: we are all want to know the answers to questions such as “Where do we come from?” and “Are we alone?” Throughout this century, popular culture has presumed the existence of other worlds and extra ...

Small-scale impulsive extreme-UV emission enhancements along network loops
Astronomy & AstrophysicsContext. Network loops are a common feature in the quiet Sun. The physical processes sustaining their energy budget are still discussed. Aims. We relied on a multi-instrumental (Solar Orbiter/EUI, Solar Orbiter/PHI, and IRIS) observation of a six-hour ...

Astrometric solar-system anomalies [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractThere are at least four unexplained anomalies connected with astrometric data. Perhaps the most disturbing is the fact that when a spacecraft on a flyby trajectory approaches the Earth within 2000 km or less, it often experiences a change in total orbital energy per unit mass.
