Everything everywhere all at once: A detailed study of GW230529
arxiv(2024)
摘要
This study investigates the origins of GW230529, delving into its formation
from massive stars within isolated binary systems. Utilizing population
synthesis models, we present compelling evidence that the neutron star
component forms first. However, the event's low signal-to-noise ratio
introduces complexities in identifying the underlying physical mechanisms
driving its formation. Augmenting our analysis with insights from numerical
relativity, we estimate the final black hole mass and spin to be approximately
5.3 M_⊙ and 0.53, respectively. Furthermore, we employ the obtained
posterior samples to calculate the ejecta mass and kilonova light curves
resulting from r-process nucleosynthesis. We find the ejecta mass to range
within 0-0.06 M_⊙, contingent on the neutron star equation of state.
The peak brightness of the kilonovae light curves indicates that targeted
follow-up observations with a Rubin-like observatory may have detected this
emission.
