Mössbauer Study of Weathering Products in Meteorites from the Atacama Desert

Magnetochemistry
During their stay at the surface of the Earth, meteorites undergo terrestrial weathering. In particular, the iron-nickel alloys and iron sulfides that are abundant in many types of meteorites transform into oxides and oxihydroxides (magnetite, maghemite,

A Laboratory Spectroscopic, Photometric, and Polarimetric Dataset of Three Ordinary Chondrites, Including the Recent Maoming Fall: Grain-size and Simulated Space-weathering Effects

The Astrophysical Journal
We present a coordinated laboratory optical data set for three equilibrated ordinary chondrites (OCs; LL5/6, L6, and H6), including the recently witnessed Maoming fall of 2025 May 28, to investigate the coupled effects of grain size, surface structure ...

Puffy Venuses: The Mass–Radius Impact of Carbon-rich Atmospheres on Lava Worlds

The Astrophysical Journal
The recent advancements in exoplanet observations enable the potential detection of exo-Venuses, rocky planets with carbon-rich atmospheres. How extended these atmospheres can be, given high carbon abundances, has not been studied.

Classification of stony meteorites and chondrules – the case of meteorite Jesenice

Geologija, 2012
In the first part of the paper there is a description about genesis of meteorites, in particularly about stony meteorites– chondrites, since meteorite Jesenice is an ordinary L chondrite. Chondrules represent main part of the mass ofchondritic meteorites.
