The longest-lasting, most energetic explosions in the universe might occur in rare stars very similar to the very first stars to form in the universe.
Is CoRoT-7d real, or is it stellar activity masquerading as a planet? Haywood et al. build a noise model to analyze CoRoT-7′s activity to find out.
Gas in clusters is predicted to cool quickly, but observations suggest otherwise. What prevents the gas from cooling? The authors explore the incidence and impact of heating by active galactic nuclei.
Astronomers hope to get lucky and discover the first evidence of plate tectonics on a planet besides Earth: remnants of continental crust in the rocky material that pollutes some white dwarfs.
A new hypothesis posits that the ice giant planets formed between the CO and N2 icelines in the Solar System’s protoplanetary disk.
What’s causing the “beads on a string” pattern of star formation around this interacting galaxy pair?
Explore an astrophysical classic describing the effect of the Universe’s expansion on the seeds of galaxies.
A new model explains Mercury’s major density with magnetism.
Some GRB-SNe pairs show interesting correlations across their light curves.
What can the growth of structure in the Universe tell us about how regular matter and dark matter scatter? The authors develop a simple framework and get model-independent constraints; read on for the answer.
