Stars Would Remember a Recent Gravitational Transition: Testing G-step Resolutions of the Hubble Tension with Red Dwarfs
Jeremy Sakstein, Harry Desmond
We test the hypothesis that Newton's gravitational constant underwent a rapid transition approximately - ago, as proposed in some resolutions of the Hubble tens…
Dark Matter-Induced Stellar Oscillations in the de Broglie Regime
Qiuyue Liang, Jeremy Sakstein
We investigate stellar oscillations driven by the time-dependent gravitational potential of ultralight dark matter (ULDM) in the de Broglie regime. The response is controlled by th…
Axions and the RR Lyrae Period-Luminosity Relation
Jeremy Sakstein, Djuna Croon
We investigate the impact of axions on the period-luminosity relation (PLR) of RR Lyrae stars. During the red giant branch phase, emission through the electron coupling cools the c…
Relativistic Stellar Oscillations from Ultralight Dark Matter
Shanae Oishi, Christopher Reyes, Jeremy Sakstein
Ultra-light dark matter, composed of bosons behaving as classical waves, can resonantly excite stellar oscillations. In this work, we investigate this phenomenon in relativistic st…
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) de…
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…
