The Effects of Accretion Feedback on Stellar Evolution in AGN Disks
Alexander J. Dittmann, Matteo Cantiello
Stars embedded in the accretion disks of active galactic nuclei (AGN) can accrete rapidly from their surroundings, dramatically altering their structure and evolution. However, fee…
MESA Isochrones and Stellar Tracks. II. Models with alpha-enhanced chemical composition
A Dotter, E Bauer, MJ Park +4
We update and expand the MESA Isochrones and Stellar Tracks (MIST) database to include variations in the alpha-capture elements, specifically [alpha/Fe]=-0.2, 0, +0.2, +0.4, and +0…
Pulsational Instability of Quasi-Stars: Interpreting the Variability of Little Red Dots
Matteo Cantiello, Jake B. Hassan, Rosalba Perna +5
The JWST discovery of "Little Red Dots" (LRDs) has revealed a population of compact, red sources at that likely host supermassive black holes (SMBHs). Recent observat…
An Extremely Luminous Flare Recorded from a Supermassive Black Hole
Matthew J. Graham, Barry McKernan, K. E. Saavik Ford +17
Since their discovery more than 60 years ago, accreting supermassive black holes in active galactic nuclei (AGN) were recognized as highly variable sources, requiring an extremely…
The Growth of the Central Black Holes in Quasi-stars
Jake Hassan, Rosalba Perna, Matteo Cantiello +3
Observations by JWST have confirmed the presence of supermassive black holes (BHs) at redshifts , lending support to scenarios in which BHs experience rapid growth thro…
Predicting Stellar Parameters of Massive Stars from Light Curves with Machine Learning
Rachel C. Zhang, Kaze W. K. Wong, Gonzalo Holgado +1
High-resolution spectroscopic measurements of OB stars are important for understanding processes like stellar evolution, but require labor-intensive observations. In contrast, phot…
Type IIb Supernova Progenitors in 3D: Variability and Episodic Mass Loss revealed by Radiation-Hydrodynamics Simulations
Jared A. Goldberg, Yan-Fei Jiang, Lars Bildsten +1
We present the first 3D Radiation-Hydrodynamics simulations of partially-stripped (, ) Yellow Supergiant (,…
Spectral Evolution of Rotating Population III Stars
Jake Hassan, Rosalba Perna, Matteo Cantiello +3
Population III (Pop III) stars, the first generation of stars formed from primordial gas, played a fundamental role in shaping the early universe through their influence on cosmic…
A Semi-Analytical Model for Stellar Evolution in AGN Disks
Alexander J. Dittmann, Matteo Cantiello
Disks of gas accreting onto supermassive black holes may host numerous stellar-mass objects, formed within the disk or captured from a nuclear star cluster. We present a simplified…
