Molecules in Cool Stars: The A2Π − X2Σ+ and the B2Σ+ − X2Σ+ Band Systems of CaCl
The Astrophysical JournalCool red giant stars exhibit absorption bands of calcium monochloride (CaCl) in the optical region. In this work, the bands of CaCl corresponding to the A ^2 Π − X ^2 Σ ^+ transition with ${v}^{{\prime} }\leqslant $ 4 and v ″ ≤ 4, and B ^2 Σ ^+ − X ^2 Σ ^

Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments.

Laboratory astrophysics under the ultraviolet, visible, and gravitational astrophysics research program: Oscillator strengths for ultraviolet atomic transitions [PDF]
The conditions within astrophysical environments can be derived from observational data on atomic and molecular lines. For instance, the density and temperature of the gas are obtained from relative populations among energy levels.

Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract The Surface Water and Ocean Topography (SWOT) mission provides unprecedented high‐resolution simultaneous observations of both sea surface height anomalies and sea surface roughness. Specifically, it enables more precise analysis of strong internal waves. Off the Amazon Shelf, in the Indonesian Seas, and near the Mascarene Ridge, internal wave

Distinct Cloud‐to‐Ground Lightning Properties in Frontal Versus Warm‐Sector Heavy Rainfall Events
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Do systematic differences in cloud‐to‐ground (CG) lightning properties—particularly return stroke number and current intensity—exist across different thunderstorm types? This question is foundational not only to the atmospheric electricity but also to advancing lightning risk prediction, which crucially depends on a robust understanding of how

Differentiating Plumes and Local Torus Segments of Enceladus
Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.
