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…
Formation of Sub-Chandrasekhar Mass Black Holes and Red Stragglers via Hawking Stars in Ultra-Faint Dwarf Galaxies
Andrew D. Santarelli, Matthew E. Caplan, Earl P. Bellinger
Presently, primordial black holes (PBHs) in the asteroid-mass window from M to M are a popular dark matter candidate. If they exist, some star…
Is there a black hole in the center of the Sun?
Matthew E. Caplan, Earl P. Bellinger, Andrew D. Santarelli
There is probably not a black hole in the center of the sun. Despite this detail, our goal in this work to convince the reader that this question is interesting and that work study…
Solar evolution models with a central black hole
Earl P. Bellinger, Matt E. Caplan, Taeho Ryu +6
Hawking (1971) proposed that the Sun may harbor a primordial black hole whose accretion supplies some of the solar luminosity. Such an object would have formed within the first 1 s…
