Four Perspectives on Neutron Stars, Pulsars, and Magnetars
Four recent articles give different perspectives on the ultra-dense, rapidly spinning, highly magnetized remnants of massive stars.

Zooming In on an Active Galactic Nucleus Outflow with JWST
Astrobites reports on how the outflows from NGC 7469’s active galactic nucleus interact with the surrounding interstellar medium.
Featured Image: Considering Craters on Uranus’s Moon Miranda
Icy solar system moons typically have sharp, well-defined craters, but Uranus’s moon Miranda has gentler surface features. What makes Miranda’s craters so subtle?
Four Stars, Many Eclipses
A flurry of eclipses, then back to eclipsing binary business as usual: what could cause such a strange light curve?
A Beginner’s Guide to Predicting Supernovae
Astrobites reports on an updated neutrino detector that may be able to alert us to impending supernovae hours in advance.
Planets May Have More Time to Form Than Previously Thought
A new study loosens the constraints on planet formation, suggesting that most protoplanetary disks stick around for at least 5 million years.
A Disruptive New Way to Form Galactic Center Stars
How did the stars at the center of our galaxy attain their curious arrangement? A new theory suggests that a shredded star paved the way for new stars to form in a narrow disk.
A NICER View of a Bursting X-ray Binary
Researchers analyze 51 X-ray bursts from a neutron star snaring material from its stellar companion, forming one of the most active low-mass X-ray binaries known.
A Tiny Flare from a Tiny Star
Astrobites reports on a tiny stellar flare from the Sun’s next-door neighbor: Proxima Centauri.
Featured Image: A Plasma-Producing Pulsar
New simulations explore plasma production and particle acceleration near the surface of a dense, highly magnetized pulsar.
A Supernova Hits a Cosmic Speed Bump
In 2021, astronomers saw a star explode, then watched as its remains strangely changed colors. A recent study suggests an explanation for this behavior: the remnants hit a speed bump.
One After Another: The Effect of Repeated Coronal Mass Ejections
Does a massive explosion of solar plasma — a coronal mass ejection — move through the solar system differently if other explosions preceded it?
