Little Red Dot $-$ Host Galaxy $=$ Black Hole Star: A Gas-Enshrouded Heart at the Center of Every Little Red Dot

Wendy Q. Sun, Rohan P. Naidu, Jorryt Matthee +30

The central engines of Little Red Dots (LRDs) may be ``black hole stars" (BH*s), early stages of black hole growth characterized by dense gas envelopes. So far, the most direct evi…

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 ( $z \sim 3 - 10$ ) objects referred to as ``Little Red Dots'' (LRDs). These objects exhibit unusual spectral features rem…

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 $1 0^{- 16}$ M $_{⊙}$ to $1 0^{- 10}$ M $_{⊙}$ are a popular dark matter candidate. If they exist, some star…
