Overreliance on fossil fuels for human energy needs, combined with the associated negative
environmental consequences in terms of greenhouse gas emissions, has shifted our focus …

Hydrogen is considered to be one of the fuels of future and liquid hydrogen (LH2)
technology has great potential to become energy commodity beyond LNG. However, for …

Recent work indicates that the nearby Galactic halo is dominated by the debris from a major
accretion event. We confirm that result from an analysis of APOGEE-DR14 element …

Abstract GRB 221009A (z= 0.151) is one of the closest known long γ-ray bursts (GRBs). Its
extreme brightness across all electromagnetic wavelengths provides an unprecedented …

Multi-dimensional fluid flow plays a paramount role in the explosions of massive stars as
core-collapse supernovae. In recent years, three-dimensional (3D) simulations of these …

We investigate systematically the dynamical mass ejection, r-process nucleosynthesis, and
properties of electromagnetic counterparts of neutron-star (NS) mergers in dependence on …

Stellar physics and evolution calculations enable a broad range of research in astrophysics.
Modules for Experiments in Stellar Astrophysics (MESA) is a suite of open source, robust …

We report on the completion of the first version of a new-generation simulation code, FLASH.
The FLASH code solves the fully compressible, reactive hydrodynamic equations and allows …

Like all true stars, massive stars are gravitationally confined thermonuclear reactors whose
composition evolves as energy is lost to radiation and neutrinos. Unlike lower-mass stars …

We review current understanding of star formation, outlining an overall theoretical framework
and the observations that motivate it. A conception of star formation has emerged in which …
