Highlights from AAS Nova: 30 March – 12 April 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.

Rapid Microlensing Classification: A Lonely SOBH Story
Astrobites reports on how we can use simulations of stellar populations to rapidly estimate the identity of the lensing object in a microlensing event.

An Update on Asteroid 2024 YR4 from JWST
Though the odds of asteroid 2024 YR4 striking Earth in 2032 have fallen to almost zero, the asteroid still has a slim chance of a collision with the Moon. New JWST observations tell us more about this potential impactor.
