A widely used method for estimating the magnetic field strength from polarization measurements likely provides accurate results for strong magnetic fields but overestimates weak magnetic field strengths.
The presence of pulsars in globular clusters and wide binary systems suggests that some proportion of pulsars must receive only a gentle kick during their formation, as a stronger natal nudge would unbind them from their systems.
Giant star ι Draconis is known to host a planet with a 511-day orbit, but careful measurements of its subtle oscillations that constrained its radius, mass, and age also revealed a second planet with an orbital period of 68 years.
High-resolution imaging reveals previously unknown, short-lived, small-scale disturbances in post-starburst galaxies, which suggests that most — if not all — post-starburst galaxies resulted from galactic mergers.
Simulations explore the formation of glycolonitrile, which might be an important precursor of the amino acid glycine as well as adenine, a component of DNA, in interstellar chemistry.
Rapidly accreting stars in the early universe might produce unique spectral features that will be observable by the James Webb Space Telescope, even as far back as a redshift of 10-13.
