Cracking Crusts Might Set a Neutron Star Speed Limit
Neutron stars seem to rotate at only half their maximum rate. Can the splitting of a neutron star’s crust explain why?
Testing a Recipe for a Star Within a Star
A Thorne–Żytkow object is a star with a neutron star at its core. New work examines whether these theoretical objects could be made, as proposed, in X-ray binary systems.
Monthly Roundup: Exo-Neptunes and Sub-Neptunes
The discovery of nearly 6,000 exoplanets has made it clear that not all planets in our galaxy resemble those in our solar system. Today’s Monthly Roundup introduces three studies involving planets entirely unlike our own.
Stellar Express: Irregular Moon Delivery
Astrobites reports on how a star flying by the early solar system could have delivered irregular moons to the giant planets.
Featured Image: Not a Supernova Remnant, But a Nova Super-Remnant
In advance of T Coronae Borealis’s much-anticipated outburst, astronomers went searching for a super-remnant surrounding the system.
Catching Core-Collapse Supernovae Before They Happen
What happens right before a massive star explodes violently in a supernova explosion? A recent study predicts an influx of pre-explosion observations will arise after the Vera C. Rubin Observatory turns on this summer, unlocking the mysteries surrounding massive stars’ ends.
Now That’s Ingenuity: First Aircraft Measurement of Winds on Another Planet
The Ingenuity helicopter made history as the first aircraft to carry out a controlled, powered flight on another planet. Now, just over a year after its final flight, Ingenuity is still enabling more firsts.
Unmasking the Little Red Dots: Active Galactic Nuclei or Not?
Astrobites reports on a deep dive into the nature of “little red dot” galaxies seen by JWST. Do they harbor active galactic nuclei, or are stars solely responsible for the extreme properties of these galaxies?
AAS 245: Day 4
On the final day of AAS 245, presenters showcased unusual dwarf galaxies, the story behind Astropy, and the highly anticipated science of the NSF–DOE Vera C. Rubin Observatory.
AAS 245: Day 3
High-energy astrophysics, massive stars, and the solar neighborhood took center stage on Day 3 of AAS 245.
AAS 245: Day 2
Talks on Day 2 of AAS 245 gave new perspectives on familiar objects, explored the icy origins of planetary systems, and highlighted the power of X-ray astronomy.
