Photometric modeling of ejecta for evaluating defensive Kinetic impacts on asteroids
Kinetic impact is the most practical planetary-defense technique, with momentum-transfer efficiency central to deflection design. We present a Monte Carlo photometric framework that couples ejecta sampling, dynamical evolution, and image synthesis to compare directly with HST, LICIACube…

Momentum transfer collision frequencies between electrons and neutrals of astrophysical interest
Theoretical calculations serve as an effective method for determining plasma temperatures within planetary atmospheres. To simulate plasma temperature, a comprehensive implementation of the energy equation is used, which is governed by five terms: conductivity, heating, cooling, adiabatic…

Tracing equatorward and poleward boundaries of the magnetospheric cusp from a simulated X-ray image
A large-scale view of the magnetospheric cusp is expected to be obtained by the Soft X-ray Imager (SXI) onboard the Solar wind Magnetosphere Ionosphere Link Explorer (SMILE). However, it is challenging to trace the three-dimensional cusp boundary from a two-dimensional X-ray image because the…

Delaminated lower slab thermal regime before slab break-off in the Pamirs: Implications from 3D kinematic modeling
The intracontinental subduction of a >200-km-long section of the Tajik–Tarim lithosphere beneath the Pamir Mountains is proposed to explain nearly 30 km of shortening in the Tajik fold–thrust belt and the Pamir uplift. Seismic imaging revealed that the upper slab was scraped and that the lower slab…

Solar EUV flux from the triple ionosophere PhotoMeter onboard the Fengyun-3E satellite
The Triple Ionosphere Photometer (TRIPM) is a scientific payload aboard the Fengyun-3E (FY-3E) satellite, which operates in a dawn−dusk orbit. It is primarily designed for nadir observations of airglow emissions at OI 135.6 nm and N2 Lyman-Birge-Hopfield (LBH) bands. Due to the satellite’s…

Simultaneous lidar observations of the sporadic Ni layer and sporadic Na layer in the MLT
Here we report on simultaneous lidar observations of sporadic Ni (Nis) layers and sporadic Na (Nas) layers in the atmosphere over Yanqing, Beijing (40.42°N, 116.02°E) from April 2019 to October 2022. During 343 nights of observation, 68 Nis and 56 Nas were observed. The seasonal variation of Nis…

Global thermospheric density response to the May 2024 extreme storm: TianMu-1 constellation observations
In this study, we analyze the impact of the May 2024 geomagnetic storm on the thermospheric mass density by using TianMu-1 constellation satellite (TM02, TM06, TM07, TM11, TM15) observations. These observations reveal intense large-scale traveling atmospheric disturbances (TADs) originating at high…

First systematic identification of triple-mode Auroral Kilometric Radiation using Arase polarization data
Auroral kilometric radiation (AKR), a fundamental plasma emission in Earth's magnetosphere, exhibits three characteristic modes: the right-handed extraordinary (R-X), left-handed ordinary (L-O) and left-handed extraordinary (L-X) modes. The role of AKR in magnetosphere−ionosphere−atmosphere…

Lithospheric magnetic variations on the Tibetan Plateau based on a 3D surface spline model, compared with strong earthquake occurrences
The National Geophysical Data Center (NGDC) of the United States has collected aeromagnetic data for input into a series of geomagnetic models to improve model resolution; however, in the Tibetan Plateau region, ground-based observations remain insufficient to clearly reflect the characteristics of…

Hydro-acoustic survey of shallow water seagrass beds using a line array of hydrophones, a case study in Xincun Lagoon, Hainan Island
Sound is considered an important aspect of an ecosystem and acoustic methods have emerged as effective tools for ecosystems research. Xincun Lagoon, Hainan Island, is an important ecosystem characterized by dense seagrass, which has been declining due to increased human activities, raising great…

Geothermal prospecting through integrated CSAMT and soil radon methods in Baozigou village, Yuncheng Basin, Fenwei Rift, China
The Yuncheng Basin, located in the southern part of the Fenwei Rift, North China, exhibits obvious crust thinning (Moho uplift of 6–8 km) and shallow Curie point depth (less than 18 km) and hence holds great potential for geothermal resources. However, geothermal exploration within the Yuncheng…

Detecting the signal cycle of the deep Earth’s dynamic processes based on GRACE satellite and CHAOS-7 model data
The GRACE (Gravity Recovery and Climate Experiment) space mission recorded temporal variation characteristics of the global gravity field at decadal timescales. The gravity data have been shown to capture the dynamics of flows within the outer core and their effects on the core–mantle boundary. We…

Integrated N2–Ar measurements of trace extraterrestrial samples
As one of the major volatile components in extraterrestrial materials, nitrogen (N2) isotopes serve not only as tracers for the formation and evolution of the solar system, but also play a critical role in assessing planetary habitability and the search for extraterrestrial life. The integrated…

Redundant source-wavelet amplitude influence in wave-equation migration/demigration flow and its removal
In wave-equation migration and demigration, the cross-correlation imaging/forwarding step implicitly injects an additional copy of the source wavelet, so that the amplitude spectrum of the wavelet is applied redundantly (effectively imposing a wavelet-spectrum weighting, often akin to an…

Stratospheric transport and residence time of Hunga volcanic aerosol
The January 2022 eruption of Hunga injected unprecedented volumes of water vapor (150 Tg) and modest sulfur dioxide (SO2) into the stratosphere, producing accelerated sulfate aerosol formation in the early plume. As the aerosols gradually spread into the global stratosphere, the role of water…

Magnetic fabric of the late Miocene extrusive rocks of the Combia Volcanic Province: Tectonic implications for the northern Andes
The accretion of the Panama–Chocó Block to the South American Plate partially drove the geological setting of the northern Andes. This event occurred in different collisional stages that are recorded in Oligocene–middle Miocene deformed rocks of the inter-Andean valley between the Western and…

Case studies of ion focusing in the downstream region of a modeled low Earth orbit spacecraft
The effect of plasma and charged particle interaction with spacecraft in a low Earth orbit (LEO) environment leads to ion focusing and the formation of an ion void in the downstream region as a result of charging. Simulations and investigations using a fixed potential imposed on the spacecraft…

Taxonomic classification of 80 near-Earth asteroids
Near-Earth objects are important not only in studying the early formation of the Solar System, but also because they pose a serious hazard to humanity when they make close approaches to the Earth. Study of their physical properties can provide useful information on their origin, evolution, and…

Identification of small impact craters in Chang’e-4 landing areas using a new multi-scale fusion crater detection algorithm
Impact craters are important for understanding the evolution of lunar geologic and surface erosion rates, among other functions. However, the morphological characteristics of these micro impact craters are not obvious and they are numerous, resulting in low detection accuracy by deep learning…

Comparison of atmospheric gravity wave event statistics between Dandong and Lhasa
Using a recognition model of atmospheric gravity waves (AGWs), we identified 519 AGW events from the OH airglow images observed at the Dandong and Lhasa stations from 2015 to 2017. The 317 AGW events detected at the Dandong station have wavelengths ranging from 30 to 60 km, periods from 14 to 20…
