Modeling the flight of meteoroid fragments with accounting for rotation [PDF]
Компьютерные исследования и моделирование, 2019 An algorithm for solving the conjugation of aerodynamic and ballistic problems, which is based on the method of modeling with the help of a grid system, has been complemented by a numerical mechanism that allows to take into account the relative movement

Meteoritic influence on sodium and potassium abundance in the lunar exosphere measured by LADEE
Geophysical Research Letters, 2016 The Lunar Atmosphere and Dust Environment Explorer (LADEE) orbited the Moon for approximately 6 months, taking data with the Lunar Dust Experiment (LDEX), Ultraviolet‐Visible Spectrometer (UVS), and Neutral Mass Spectrometer (NMS).

Meteoroid Engineering Model (MEM): A Meteoroid Model For The Inner Solar System [PDF]
Earth, Moon, and Planets, 2004 In an attempt to overcome some of the deficiencies of existing meteoroid models, NASA’s Space Environments and Effects (SEE) Program sponsored a 3 year research effort at the University of Western Ontario. The resulting understanding of the sporadic meteoroid environment – particularly the nature and distribution of the sporadic sources – were then ...

Formation, Structure, and Detectability of the Geminids Meteoroid Stream
The Planetary Science Journal, 2023 The Geminids meteoroid stream produces one of the most intense meteor showers at Earth. It is an unusual stream in that its parent body is understood to be an asteroid, (3200) Phaethon, unlike most streams, which are formed via ongoing cometary activity.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Advanced Science, EarlyView.Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,
