Survivability of Moon Systems Around Ejected Gas Giants [PDF]
, 2018 We examine the effects that planetary encounters have on the moon systems of ejected gas giant planets. We conduct a suite of numerical simulations of planetary systems containing three Jupiter-mass planets (with the innermost planet at 3 AU) up to the point where a planet is ejected from the system. The ejected planet has an initial system of 100 test-

Lunatic Stocks: Moon Phases as Irregular Sampling Features for Pattern Recognition in the Stock Markets [PDF]
arXiv, 2021 This paper presents a novel idea on incorporating the Moon phases to the classic Gregorian (Solar) calendar time sampling methods for finding meaningful patterns in the stock markets. The four main Moon phases (New Moon, First quarter, Full Moon and Third quarter) are irregular in time but with well defined sampling structure as the Moon orbits the ...

Measuring Mountains on the Moon [PDF]
Math Horizons 26 (2019), no. 4, 24-25, 2019 Following a technique of Galileo we compute the height on a mountain on the Moon. It is based on a simple observation that precisely on a half Moon day, the Earth, the Moon, and the Sun form the vertices of a right triangle with the Moon at the 90 degree vertex.

Exoplanets Torqued by the Combined Tides of a Moon and Parent Star [PDF]
, 2018 In recent years, there has been interest in Earth-like exoplanets in the habitable zones of low mass stars ($\sim0.1-0.6\,M_\odot$). Furthermore, it has been argued that a large moon may be important for stabilizing conditions on a planet for life. If these two features are combined, then an exoplanet can feel a similar tidal influence from both its ...

Formation of the Moon: a new mechanism [PDF]
arXiv, 2014 Understanding the Moon's formation mechanism is necessary for studying not only the Moon itself, but also the evolution, formation, habitability, and structure of other planets and the moons in the Solar system and in extrasolar planetary systems. In this paper, I suggest a mechanism of the Moon formation. I posit that the Moon came into existence from

The Planetary Science JournalWe present a constraint matrix to be used in the determination of gravity field models from spacecraft tracking data that uses information from topography and that allows for the direct determination of lateral variations in crustal density. Our approach

Traditional ecological knowledge and flood risk management: A preliminary case study of the Rwenzori
Jàmbá, 2018 The shift from flood protection to flood risk management, together with recent arguments on incorporating culture in managing risk, underscores the application of traditional ecological knowledge (TEK) in managing disasters from flood hazards.

Advanced Electronic Materials, EarlyView.This paper presents a self‐aligned heterojunction gate phototransistor that eliminates the need for high‐precision alignment tools. The device achieves a high responsivity of 2.9 × 105 A W−1 and a specific detectivity of 9.6 × 1013 Jones, comparable to the performance of non‐self‐aligned devices requiring complex fabrication.

MoonLITE – Technological feasibility of the penetrator concept [PDF]
, 2008 Introduction: While the surface missions to the Moon of the 1960s and 1970s achieved a great deal, scientifically a great deal was also left unresolved. The recent plethora of lunar missions (flown or proposed) reflects resurgence in interest in the Moon,

Enhancing Cycle Life in Superoxide‐Based Na–O2 Batteries by Reducing Interface Reactivity
Advanced Energy Materials, EarlyView.A new sodium–oxygen (Na–O2) battery is designed with highly active vanadium phosphide (VP) nanoparticles as a catalyst, an ether/ionic liquid‐based electrolyte, and an effective sodium bromide (NaBr) anode protection layer. This designed Na–O2 cell that produces NaO2 is able to reduce the interfacial reactivity between cell materials and the product to
