The Astrophysical Journal LettersM-type asteroids are historically thought to be exposed metallic cores of differentiated planets with a composition dominated by pure iron and nickel. However, recent spectral and radar observations reveal an insufficient number of M-type asteroids in ...

Photoluminescence and Cathodoluminescence of the Solid Cometary Substance
Open Astronomy, 2019 We have proposed that solar ultraviolet and corpuscular radiations may excite photoluminescence and cathodoluminescence of the solid cometary substance including mineral halos of comets.

Finding the aten asteroids posing potential danger for Earth
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007 We made the research of orbit evolutions of 321 aten asteroids on the 400 years time interval (1800–2200). We found five asteroids which come close to the Earth at a distance less than 150000 km.

Identifying LL Chondrite Near-Earth Asteroids Using LL Chondrite Reflectance Spectra
The Astrophysical Journal LettersMost near-Earth objects are thought to originate from the collisional fragments of the main asteroid belt. One question that remains to be resolved is the proportion of near-Earth objects sampling the core area material of the parent body to the outer ...

Disasters, Volume 50, Issue 3, July 2026.Abstract This study investigates the claim that women are disproportionately more likely to die in disasters by reviewing existing data sources and compiling new datasets on sex‐differentiated disaster fatalities in the twenty‐first century. The analysis is structured by disaster type, covering geophysical, meteorological, climatological, hydrological,

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds
Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Asteroid surface materials: Mineralogical characterizations from reflectance spectra [PDF]
Mineral assemblages analogous to most meteorite types, with the exception of ordinary chondritic assemblages, have been found as surface materials of Main Belt asteroids.
