Highlights from AAS Nova: 11–24 May 2025

AAS Nova provides brief highlights of recently published articles from the AAS journals, i.e., The Astronomical Journal (AJ), The Astrophysical Journal (ApJ), ApJ Letters, ApJ Supplements, The Planetary Science Journal, and Research Notes of the AAS. The website's intent is to gain broader exposure for AAS authors and to provide astronomy researchers and enthusiasts with summaries of recent, interesting research across a wide range of astronomical fields.

The following are the AAS Nova highlights from the past two weeks; follow the links to read more, or visit AAS Nova for more posts. You can also sign up to receive emails each time a new post is published.

Creation from Collapse: Making Elements in a White Dwarf's Final Moments
Some neutron stars might arise from the collapse of a white dwarf. Simulations show that this transformation is likely accompanied by a burst of element creation.

A New Theory for Little Red Dots: Shredded Stars Feeding Growing Black Holes
Could tidal disruption events, which happen when a star gets too close to a black hole, explain the unusual properties of little red dot galaxies?

Are Hot Sub-Neptunes Just Failed Hot Jupiters? Maybe.
Astrobites reports on potential formation mechanisms for hot Neptunes, the rarest type of sub-Neptune exoplanets.

Featured Image: The Last Asteroid Pair Discovered by Arecibo
The 1,000-foot-wide Arecibo Telescope discovered nearly 60 binary or triple asteroid systems. 2020 BX12 was the final binary asteroid discovered with Arecibo before the telescope collapsed in 2020.

From Gas to Cluster: Simulating Star Formation in the Early Universe
How do globular clusters, some of the universe’s oldest objects, originate? Recent simulations of early universe star formation provide potential pathways for their formation and how JWST might be able to spot their high-redshift progenitors.

Winds, Jets, and Wigglings from Young Stars and Their Disks
New JWST observations provide a richly detailed look at the jets from young stars still shrouded in dusty disks.

Did That Supermassive Black Hole Rip Apart a Star, or Is It Eating Lunch Like Normal?
Astrobites reports on a radio search for stars that have been ripped apart by supermassive black holes.

Black Hole vs. Magnetized Neutron Star: Matchup Predictions
Monster shocks and a "pulsar-like" black hole phase might form when a black hole collides with a neutron star. Could this cosmic clash produce observable electromagnetic signals?
