commonly known as a ‘kilonova’ (also known as ‘macronova’). Kilonovae are day to week-long thermal, supernova-like transients, which are powered by the radioactive decay of heavy, neutron-rich elements synthesized in the expanding merger ejecta (Li and Paczyński1998). They provide...
Radioactive decay of these unstable nuclei powers a rapidly evolving, approximately isotropic thermal transient known as a “kilonova”, which probes the physical conditions during the merger and its aftermath. Here I review the history and physics of kilonovae, leading to the current paradigm of ...
Kilonovae produced by the coalescence of compact binaries with at least one neutron star are promising standard sirens for an independent measurement of the Hubble constant (H0). Through their detection via follow-up of gravitational-wave (GW), short gamma-ray bursts (sGRBs) or optical surveys,...
Since it is not yet practical to derive such complete information from experimental data, current understanding of the kilonova opacities relies on theoretical atomic calculations. In fact, there has been significant progress in the atomic calculations for application to kilonovae in the past decade ...
kilonovae (KNe) associated with the mergers, can provide an independent distance measurement to individual mergers that is potentially accurate to within a few percent. There are four reasons why the KN-EPM overcomes the major uncertainties commonly associated with this method in supernovae: (1)...
Roman will provide researchers with a powerful tool for observing extremely distant kilonovae. This is due to the expansion of space. Light that left stars billions of years ago isstretched into longer, redder wavelengths, known as infrared light, over time. Since Roman specializes in capturing ...
Although there is uncertainty in the explosion scenario due to difficulty in measuring the explosion epoch, we find PS17cke to be a plausible kilonova candidate from the model comparisons. 展开 关键词: surveys supernovae: general transients: black hole neutron star mergers ...
Keywords: kilonovae; compact star mergers; nucleosynthesis 1. Introduction A series of exciting observations from a few different events have recently transformed the study of kilonovae [1], late afterglows of some transient events, into an exciting and true multimessenger field of high-energy astro...
