Simulations suggest that impacts between planetesimals can produce chondrules — round inclusions of once-melted silicates — similar to what is seen in meteorites.
The Vera C. Rubin Observatory will discover ~129 candidate near-Earth objects each night, necessitating careful consideration of which objects should be followed up on with other facilities.
A recent fast X-ray transient may have been due to a supernova that developed within a dense envelope of material, providing evidence that could link several types of high-energy transients.
A detailed census of 100 pulsars, including six millisecond pulsars, yields sensitive measurements of dispersion and rotation measures, polarization, timing solutions, and more.
Researchers report the discovery of 621 “winged” radio galaxies, 382 of which are “X” shaped and 239 of which are “Z” shaped, with a further 403 candidates awaiting confirmation.
The eccentricities of binary stars that orbit one another within a few astronomical units follow a simple Rayleigh distribution, an outcome that may be traceable back to excitation by circumbinary disks.
