A survey of ultramassive white dwarfs suggests that these objects form either in a way that induces no strong magnetism, or that the magnetic fields dissipate rapidly.

Using observations from the Parker Solar Probe’s three closest approaches to the Sun, researchers have found the first firm evidence that the Sun’s 5-minute oscillations stretch into the solar wind.

Based on a recent survey of trans-Neptunian objects, researchers have proposed a new surface classification scheme that divides objects based on their infrared brightness.

Luminous red novae are estimated to contribute roughly 25% as much dust as core-collapse supernovae do, and the lower expansion velocities of luminous red novae may result in less dust destruction by shocks.

Using JWST’s exceptionally fine resolution, astronomers have ruled out the presence of multiple lensed images of J0025–0145 and estimated an intrinsic Eddington ratio of 4.9 for the quasar.

New spectroscopic evidence suggests that the globular cluster NGC 6569 is actively losing stars through tidal stripping; these stars will become part of the galactic bulge field population.
