Evolutionary Tracks and Spectral Properties of Quasi-stars and Their Correlation with Little Red Dots
Andrew D. Santarelli, Ebraheem Farag, Earl P. Bellinger +4
JWST has revealed a population of red, compact, high-redshift () objects referred to as ``Little Red Dots'' (LRDs). These objects exhibit unusual spectral features rem…
MESA-QUEST: Tracing the formation of direct collapse black hole seeds via quasi-stars
Andrew D. Santarelli, Claire B. Campbell, Ebraheem Farag +3
The origin of the first supermassive black holes (SMBHs) observed at redshifts remains one of the most challenging open questions in astrophysics. Their rapid emergence s…
Solar-like oscillations in accreting pre-main sequence stars: Insights and prospects
Johannes Jørgensen, Konstanze Zwintz, Ebraheem Farag +2
We present theoretical predictions for solar-like oscillators in the pre-main sequence phase of stellar evolution. Our pre-main sequence models start from a stellar seed of 0.01 so…
Nuclear Neural Networks: Emulating Late Burning Stages in Core Collapse Supernova Progenitors
Aldana Grichener, Mathieu Renzo, Wolfgang E. Kerzendorf +7
One of the main challenges in modeling massive stars to the onset of core collapse is the computational bottleneck of nucleosynthesis during advanced burning stages. The number of…
