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…
MESA-QUEST: Modeling Quasi-Stars in MESA
Claire B. Campbell, Andrew D. Santarelli, Matthew E. Caplan
Supermassive black hole formation remains an unsolved problem. Quasi-stars have been suggested as a viable heavy-seeding mechanism. In this work, we implement methods for modeling…
The Sun's Dark Core: Helioseismic and neutrino flux constraints on a compact solar center
Earl Patrick Bellinger, Matt E. Caplan
As dark matter appears to comprise most of the Galactic mass, some of it may accumulate in the cores of stars, thereby making the Sun a laboratory for constraining various dark mat…
