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…
Slowly Rotating Neutron Stars in Aether Scalar-Tensor Theory
Christopher Reyes, Jeremy Sakstein
Aether Scalar-Tensor theory is a relativistic alternative gravity model that behaves like cold dark matter on cosmological scales while predicting the MOND force-law in astrophysic…
Neutron Stars in Aether Scalar-Tensor Theory
Christopher Reyes, Jeremy Sakstein
Aether Scalar-Tensor theory is a modification of general relativity proposed to explain galactic and cosmological mass discrepancies conventionally attributed to dark matter.~The t…
Parameterized Post-Tolman-Oppenheimer-Volkoff Framework for Screened Modified Gravity with an Application to the Secondary Component of GW190814
Christopher Reyes, Jeremy Sakstein
The secondary component of GW190814 has mass in the range --, placing it within the lower mass gap separating neutron stars from black holes. According to t…
