Astronomy and astrophysics

Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space-craft-borne instruments of the electromagnetic radiation and high-energy particles emitted by celestial bodies.

    Observations that molecular gas in NGC 300 is spatially uncorrelated with high-mass stars are attributed to rapid evolution, with molecular clouds quickly destroyed by stellar feedback, and low star-formation efficiency.

    The merger of two white dwarfs created a massive, hot, luminous, rotating and magnetized star with a lifetime of several thousand years, which will collapse into a type Ic supernova.

    A rare type of supernova—triggered by the collapse of a rapidly rotating single star—could have provided more than 80 per cent of the r-process elements in the Universe.

    Leveraging the precision of K2 and TESS, Bowman et al. have detected variability in galactic and Magellanic blue supergiants that is due to low-frequency gravity waves in their interiors.

    A predominance of small grains (tens of nanometres in size) over larger grains and the corresponding near- to mid-infrared excess radiation from H ii regions around massive stars and supernovae has been difficult to explain. Hoang et al. propose a radiative torque disruption method for large dust grains that fits with the observational constraints.
