Reduction of CO2 and Related Compounds with a Low‐Valent CaI Synthon
ChemistryEurope, Volume 3, Issue 4, July 14, 2025.The reduction of CO2, CS2, or carbodiimide with a CaI synthon results in formation of calcium complexes with CO32−, CS22− or C–C coupled carbodiimide dianions. Differences between reduction of these reagents with the CaI synthon and established MgI complexes are discussed. Combined experimental and computational investigations give insight in the first

Supernova theory and supernova 1987A
The Astrophysical Journal, 1987 The implications of Supernova 1987A are examined and compared with theoretical expectations. The relatively low luminosity follows from the progenitor having lower than solar abundances. The explosion energy is (1.0-2.0) x 10 to the 51st ergs for a 15 solar mass star.

Supernova 1604, Kepler’s Supernova, and Its Remnant [PDF]
, 2016 Supernova 1604 is the last Galactic supernova for which historical records exist. Johannes Kepler's name is attached to it, as he published a detailed account of the observations made by himself and European colleagues. Supernova 1604 was very likely a Type Ia supernova, which exploded 350 pc to 750 pc above the Galactic plane.
