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.

Underground nuclear astrophysics studies with CASPAR

EPJ Web of Conferences, 2016
The drive of low-energy nuclear astrophysics laboratories is to study the reactions of importance to stellar burning processes and elemental production through stellar nucleosynthesis, over the energy range of astrophysical interest.

Interpreting Changes in Global Methane Budget in a Chemistry‐Climate Model Constrained With Methane and Isotopic Observations

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract The continuous increase in atmospheric methane (CH4) concentrations over the past few decades has become a major concern due to its strong role as a greenhouse gas contributing to climate change. In this work, we investigate the changes in the global methane budget using a global chemistry‐climate model constrained with methane and its ...

Effects of Gamma Ray Bursts in Earth Biosphere

, 2009
We continue former work on the modeling of potential effects of Gamma Ray Bursts on Phanerozoic Earth. We focus on global biospheric effects of ozone depletion and show a first modeling of the spectral reduction of light by NO2 formed in the stratosphere.

Anthropogenically Stimulated Carbonate Dissolution in the Global Shelf Seafloor Is Potentially an Important and Fast Climate Feedback

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Carbonate mineral production and dissolution regulate atmospheric carbon dioxide (CO2) concentrations via modulation of the ocean alkalinity content. The anthropogenic rise in atmospheric CO2 reduces calcification rates and enhances calcium carbonate dissolution, which increases ocean alkalinity, counteracts acidification, and stimulates ocean

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 ...
