Supernovae are vitally important in the chemical and dynamical evolution of galaxies, but we don't yet fully understand the physics that produce these explosions. This new work simulates the turbulent instabilities in a star at the brink of core-collapse.
Incorporating all the effects relevant to star formation into accurate simulations of the interstellar medium is a major frontier in astrophysics. These authors start to tackle the effects of chemical composition.
Understanding the uncertainties involved in the techniques used to detect exoplanets is an important aspect of the search for life beyond the Earth. What role could phenomenon like sunspots play in planet detection?
Assuming every star in a cluster has the same age and metallicity is a powerful simplification, but it may not be true.
A new cluster of galaxies discovered in the early universe using the Sunyaev-Zel’dovich (SZ) effect could have important consequences for studying galaxy evolution and cosmology.
The general picture of galaxy formation was hashed out in the 1960s and 70s. In the decades since, countless lines of theoretical and observational evidence have suggested additional mechanisms which can influence the evolution of galaxies, and sorting out which of these are the most important is among the most lively fields in astrophysics.
In my [last post](https://astroph.wordpress.com/2010/11/30/formation-of-cold-filamentary-structure-from-wind-blown-superbubbles/), I wrote about an interesting application of hydrodynamical simulations to a particular astrophysical problem, so when I saw this excellent introduction to the inner-workings of these simulation codes, I couldn't resist highlighting it.
We often think of galaxies as collections of stars, but this simple picture omits (among other things) the fascinating interstellar medium (ISM)!
