Galactic Condensates composed of Multiple Axion Species
Joshua Eby, Madelyn Leembruggen, Lauren Street +2
Ultralight scalar dark matter has been proposed to constitute a component of dark matter, though the minimal scenarios have increasingly become constrained. In this work, we analyz…
Global view of QCD axion stars
Joshua Eby, Madelyn Leembruggen, Lauren Street +2
Taking a comprehensive view, including a full range of boundary conditions, we reexamine QCD axion star solutions based on the relativistic Klein-Gordon equation (using the Ruffini…
On Approximation Methods in the Study of Boson Stars
Joshua Eby, Madelyn Leembruggen, Lauren Street +2
We analyze the accuracy of the variational method in computing physical quantities relevant for gravitationally bound Bose-Einstein condensates. Using a variety of variational ansä…
QCD Axion Star Collapse with the Chiral Potential
Joshua Eby, Madelyn Leembruggen, Peter Suranyi +1
In a previous work, we analyzed collapsing axion stars using the low-energy instanton potential, showing that the total energy is always bounded and that collapsing axion stars do…
