Collapse of Magnetized White Dwarfs as site of Heavy Element Formation and Kilonova Signal
Tetyana Pitik, David Radice, Daniel Kasen +3
We present the first end-to-end calculation connecting the accretion-induced collapse (AIC) of a magnetized, rapidly rotating white dwarf to observable kilonova signatures, combini…
Gamma-ray Signatures of r-Process Radioactivity from the Collapse of Magnetized White Dwarfs
Tetyana Pitik, Yong-Zhong Qian, David Radice +1
We predict the gamma-ray line emission from -process nuclei synthesized in the ejecta of the accretion-induced collapse (AIC) of a magnetized, rapidly rotating white dwarf. Usin…
Supernova production of axion-like particles coupling to electrons, reloaded
Damiano F. G. Fiorillo, Tetyana Pitik, Edoardo Vitagliano
We revisit the production of axion-like particles (ALPs) coupled to electrons at tree-level in a relativistic plasma. We explicitly demonstrate the equivalence between pseudoscalar…
Energy transfer by feebly interacting particles in supernovae: the trapping regime
Damiano F. G. Fiorillo, Tetyana Pitik, Edoardo Vitagliano
Feebly interacting particles, such as sterile neutrinos, dark photons, and axions, can be abundantly produced in the proto-neutron star (PNS) formed in core-collapse supernovae (CC…
Gamma-ray bursts and kilonovae from the accretion-induced collapse of white dwarfs
Patrick Chi-Kit Cheong, Tetyana Pitik, LuÃs Felipe Longo Micchi +1
We present the first seconds-long 2D general relativistic neutrino magnetohydrodynamic simulations of accretion-induced collapse (AIC) in rapidly rotating, strongly magnetized whit…
