Understanding massive stars is essential for a variety of branches of astronomy including
galaxy and star cluster evolution, nucleosynthesis and supernovae, pulsars, and black holes. It …

Systemic protothecosis was diagnosed in 17 Australian dogs between 1988 and 2005.
There was a preponderance of young-adult (median 4 years), medium- to large-breed dogs. …

We review our current understanding of the progenitors of both long and short duration
gamma-ray bursts (GRBs). Constraints can be derived from multiple directions, and we use three …

The presence of a nearby companion alters the evolution of massive stars in binary systems,
leading to phenomena such as stellar mergers, x-ray binaries, and gamma-ray bursts. …

Double neutron star (DNS) systems represent extreme physical objects and the endpoint of
an exotic journey of stellar evolution and binary interactions. Large numbers of DNS systems …

We substantially update the capabilities of the open-source software instrument Modules for
Experiments in Stellar Astrophysics (MESA). MESA can now simultaneously evolve an …

The evolution of rotating stars with zero-age main-sequence (ZAMS) masses in the range 8–25
M⊙ is followed through all stages of stable evolution. The initial angular momentum is …

Context. The Tarantula Nebula in the Large Magellanic Cloud is our closest view of a
starburst region and is the ideal environment to investigate important questions regarding the …

We investigate the evolution of the surface properties of models for rotating massive stars, ie,
their luminosities, effective temperatures, surface rotational velocities, and surface …

We present grids of massive star evolution models at four different metallicities ($Z=0.004,
0.002, 0.001, 0.00001$). The effects of rotation on the stellar structure and the transport of …
