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.

Finding the Best Wavelengths to Study the Sun's Magnetic Field
Scientists have taken stock of the Sun's many spectral lines to find the best way to measure its magnetic field — key to understanding a wide range of explosive phenomena.

How Quickly Do We Need to Track Down the Next Neutron Star Merger?
When gravitational waves from colliding neutron stars rumbled through our detectors in 2017, astronomers raced to track down the light emitted in the collision — but caught critical wavelengths too late to distinguish between competing theories.

Featured Image: Making the First Stars in Spinning Clouds
Researchers use simulations to explore the possible masses of the first stars in the universe — which may determine whether those stars are still present in the universe today.

3 March 2023
Bangs Without Flashes: Gravitational Waves and Elusive Neutrinos
Astronomers can learn much from gravitational waves and high-energy neutrinos separately, but could gain much more if both were ever spotted together emanating from the same source. A new publication the Astrophysical Journal summarizes ongoing efforts to do just that.

1 March 2023
Hot Days and Cloudy Nights on a “Heavy Metal” Exoplanet
A well-known hot Jupiter exoplanet gets a new phase curve thanks to JWST, and the results support the hypothesis that this scorching planet has metallic clouds.

27 February 2023
Finding High-Redshift Dead Galaxies (But for Real This Time)
Astrobites reports on a new way to pick out dead galaxies that may help us learn how star formation stops in the early universe.
