The location of the upper edge of the pair-instability supernovae black hole mass gap
Jeremy Sakstein, Djuna Croon
Gravitational wave observations are beginning to probe the upper edge of the pair-instability supernova (PISN) black hole mass gap, a key prediction of stellar evolution. In this w…
Precision constraints on stellar physics from main sequence detached eclipsing binaries
Mitchell T. Dennis, Harry Desmond, Jeremy Sakstein
We present a Bayesian framework to constrain {mass (), metallicity (), stellar age (), and the convective mixing length parameter ()} in main-sequence (MS)…
Millicharged Particle Constraints from Asymptotic Giant Branch Stars
Damiano F. G. Fiorillo, Giuseppe Lucente, Jeremy Sakstein +1
We investigate the effect of millicharged particles (MCPs) with electric charge and mass on the late-stage evolution phases of low-mass stars in globular clusters.…
Unifying Early and Late Dark Energy: Dynamical Requirements and Obstructions
William Giarè, Jeremy Sakstein
We investigate whether early- and late-time dark energy could arise from a single scalar field. Adopting a bottom-up perspective, we first identify the sequence of dynamical regime…
Millicharged Particle Production During Late-Stage Stellar Evolution
Damiano F. G. Fiorillo, Giuseppe Lucente, Jeremy Sakstein +1
Stars are natural sources of feebly interacting particles, including putative particles with mass and electric charge . The emission of such millicharged particles (MCPs…
The Black Hole Mass Gap as a New Probe of Millicharged Particles
Damiano F. G. Fiorillo, Giuseppe Lucente, Jeremy Sakstein +2
We investigate the impact of millicharged particles (MCPs) on massive stars undergoing pulsational pair-instability supernovae and on the location of the lower edge of the black ho…
