Expansion in Higher Harmonics of Boson Stars using a Generalized Ruffini-Bonazzola Approach, Part 1: Bound States
Joshua Eby, Peter Suranyi, L. C. R. Wijewardhana
The method pioneered by Ruffini and Bonazzola (RB) to describe boson stars involves an expansion of the boson field which is linear in creation and annihilation operators. In the n…
Decay of Ultralight Axion Condensates
Joshua Eby, Michael Ma, Peter Suranyi +1
Axion particles can form macroscopic condensates, whose size can be galactic in scale for models with very small axion masses eV, and which are sometimes referred t…
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…
