The effect of terrestrial weathering on the mineralogy and petrologic (sub)types of CM chondrites explored by kinetic modeling and laboratory experiments

Meteoritics &Planetary Science, EarlyView.
Abstract Terrestrial weathering alters the chemical and isotopic composition, and mineralogy, of meteorites; its effects on ordinary chondrites are well‐studied, but relatively little is known about the susceptibility of carbonaceous chondrites. We combined laboratory experiments, whereby Chwichiya 002 (C3‐ung find), Murchison (CM2 fall) and Kolang ...

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Measurement and Modeling of Electron Temperature in Laboratory Photoionized Plasmas Relevant to Astrophysics

The Astrophysical Journal
The electron temperature of photoionized plasmas characterizes the thermalization of photoelectrons, impacts the charge-state distribution, emissivity, and opacity through atomic recombination processes, and is needed to perform detailed comparisons with

Astrophysics experiments with radioactive beams at ATLAS

AIP Advances, 2014
Reactions involving short-lived nuclei play an important role in nuclear astrophysics, especially in explosive scenarios which occur in novae, supernovae or X-ray bursts.

Dissociation and Cooling Dynamics of 2-cyanoindene Monocations: Survival of Small PAHs in Harsh Interstellar Radiation Fields

The Astrophysical Journal
The molecule, 2-cyanoindene, C _10 H _7 N (2CNI) is the only cyanosubstituted polycyclic aromatic hydrocarbon (PAH) detected in space, for which the hydrocarbon counterpart, indene, has also been observed in the same astrochemical environment—the ...

Researchers' Well‐Being Through My Academic Career in Japan, Germany and USA

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Upon development of my academic career in Japan, Germany, and USA, I have increasingly recognized the importance of researchers' well‐being. While the research lifestyles in these three countries were distinct, it has been essential for me to maintain good well‐being for the sustainable development of my academic career.

The A2Π–X2Σ+ Band System of ScO for M-type Star Spectral Analysis

The Astrophysical Journal
M-type stars are the most abundant stars in our Galaxy. Their visible spectra are characterized by strong TiO and VO absorption bands with occasional ScO bands near 6000–6100 Å.

Strong Field QED, Astrophysics, and Laboratory Astrophysics

Astrophysical compact objects, such as magnetars, neutron star mergers, etc, have strong electromagnetic fields beyond the Schwinger field ($B_c = 4.4 \times 10^{13}\, {\rm G}$). In strong electric fields, electron-positron pairs are produced from the vacuum, gamma rays create electron-positron pairs in strong magnetic fields, and propagating photons ...
