Revisiting dynamics of Sun center relative to barycenter of Solar system [PDF]

open access: yesJournal of Space Safety Engineering (2022), 2011
We introduce here in the current research the revisiting of approach to the dynamics of Sun center relative to barycenter of Solar system by using self-resulting photo-gravitational force of the Sun as the main reason of such motion. In case of slowly moving in the direction outwards with respect to the initial position of barycenter of Solar system ...

Elucidating the Supramolecular Interaction of Positively Supercharged Fluorescent Protein with Anionic Phthalocyanines

open access: yesAdvanced Biology, EarlyView.
Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the

The Kalmag model as a candidate for IGRF-13

open access: yesEarth, Planets and Space, 2020
We present a new model of the geomagnetic field spanning the last 20 years and called Kalmag. Deriving from the assimilation of CHAMP and Swarm vector field measurements, it separates the different contributions to the observable field through ...

Stability of Parker's Solar Wind Solution Near the Solar Surface [PDF]

open access: yes, 2020
Stability of Parker's steady solar wind solution near the solar surface is systematically investigated by posing a Sturm-Liouville problem for this solution. Parker's solar wind solution, whether it turns into a breeze or a supersonic wind depending on the pressure in the interstellar medium, is shown to describe the solar wind to start in a stable way

Material Challenges and Alloy Selection for Particle/s‐CO2 Heat Exchangers in Concentrated Solar Power Systems

open access: yesAdvanced Engineering Materials, EarlyView.
Combining supercritical CO2 (s‐CO2) cycles with particle‐based heat transfer media holds great potential in concentrated solar power plants but poses enormous material challenges. The particle/s‐CO2 heat exchanger must withstand extreme conditions, including high temperatures, pressures, CO2 corrosion, and erosion.

Ceres: Organic‐Rich Sites of Exogenic Origin?

open access: yesAGU Advances
Ceres, the largest object in the asteroid belt, is the only potential ocean world in the inner Solar System. Previous studies identified deposits of aliphatic organics in and around the Ernutet crater, and at small locations at Inamahari and Urvara ...

Morphology of the Excited Hydroxyl in the Martian Atmosphere: A Model Study—Where to Search for Airglow on Mars?

open access: yesRemote Sensing
Monitoring excited hydroxyl (OH*) airglow is broadly used for characterizing the state and dynamics of the terrestrial atmosphere. Recently, the existence of excited hydroxyl was confirmed using satellite observations in the Martian atmosphere.

Study on the Relationship between BO–LID and LeTID in Czochralski-Grown Monocrystalline Silicon

open access: yesEnergies, 2020
Most research about Light and elevated Temperature Induced Degradation (LeTID) is focused on multicrystalline silicon (mc-Si). In this work, the degradation kinetics of Czochralski-grown monocrystalline silicon (Cz-Si) induced by light at an elevated ...

Origin of the Solar System [PDF]

open access: yes, 1981
In the preceding chapters we have seen how drastically in situ measurements in space have changed our views of the properties of cosmic plasmas. It has also been pointed out that these changes are not likely to be confined to the region where the measurements have been made.

Solar System binaries [PDF]

open access: yesProceedings of the International Astronomical Union, 2005
The discovery of binaries in each of the major populations of minor bodies in the solar system is propelling a rapid growth of heretofore unattainable physical information. The availability of mass and density constraints for minor bodies opens the door to studies of internal structure, comparisons with meteorite samples, and correlations between bulk-
