Highlights from AAS Nova: 13–26 October 2024

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.

Tracing Huge, Distant Structures in the Universe
Space is filled with structures that we can't see directly. How do astronomers trace the underlying dark-matter distribution of the universe?

23 October
Searching Five Million Stars for Disks, Debris, and Dyson Spheres
A data-driven approach identifies stars with interesting infrared emission without relying on computationally expensive modeling.

Star Alignment and a Planet’s Origin: The Case of HIP 65426
Astrobites reports on an analysis of the orbital architecture of JWST’s first directly imaged exoplanet using time-series photometry data from the Transiting Exoplanet Survey Satellite.

On the Run: Hypervelocity Stars and Their Links to Type Ia Supernovae
While Type Ia supernovae have been used to determine cosmological distances and study the expansion of the universe, their origins are still under investigation. Recent simulations point to a double-detonation scenario being the catalyst for some of these extremely energetic events.

Gliese 229 B’s Newfound Companion Solves Brown Dwarf Mystery
New observations show that Gliese 229 B is two brown dwarfs rather than one, resolving the mismatch between its measured mass and predictions of evolutionary models.

15 October 2024
Blowing Away Star Formation with Warm Molecular Gas
Astrobites reports on a study that uses JWST to investigate how warm, star-forming molecular gas is blown away by active galactic nuclei.

14 October 2024
Close Encounters of Distant Stellar Partners
Widely spaced binary stars might get voted "Least Likely to Interact," but they might surprise you: new research shows that under the right conditions, these distant stellar companions can get catastrophically close.
