MNRAS on the OUPblog
An international team of astronomers has discovered a small, very blue helium-rich, and hot star called UVO 0825+15, which has a surface extremely rich in lead and other heavy metals. Only the fourth 'heavy-metal subdwarf' discovered, and the second to be variable, the new star raises major questions about how these stars form and work.
A possible cause of the Big Bang and current acceleration of the Universe
The Big Bang theory predicts that there was a powerful repulsive force at the beginning of the expanding of the Universe. A common hypothesis of the cause of the Big Bang is a short-term repulsive field, the so-called “inflaton".
Adding a new dimension to the early chemistry of the solar system
What was our solar system composed of at the beginning of its formation? Using sophisticated computer simulations, researchers from France and Australia have obtained new insights into the chemical composition of the dust grains that formed in the early solar system which went on to form the building blocks of the terrestrial planets.
An efficient way to find monsters with two faces
Quasars are distant galactic nuclei generating spectacular amounts of energy by matter accretion onto their central supermassive black holes. The precise geometry and origin of this huge activity are still largely unknown, and direct spatial resolution of the emitting regions from such distant monsters is not currently possible.Read full blog post
