[institut] [phys4phys] Naučno-stručni skup AOB, sreda 11.12. u 12h

[Natasa Bon]

Poštovane kolege,


Pozivam vas da prisustvujete Naučno-stručnom skupu koji će se održati u 
biblioteci Astronomske opservatorije u Beogradu u sredu, 11.12.2024. sa 
početkom u 12h.

Predavač: Gregory Vereshchagin, ICRANet

Naslov predavanja: Electron-positron pair creation in electrosphere of 
compact astrophysical objects

Kratak apstrakt:
Hypothetical quark stars or neutron stars with very stiff equations of 
state may develop strong electric fields on their surfaces. When 
electric field strength exceeds the Schwinger limit prolific 
electron-positron pair creation becomes possible. At zero temperature 
this process is blocked due to the quantum degeneracy of electrons; 
however, it should be possible when compact object is just formed. 
Recently the mechanism of pair creation in hot electrosphere was 
revisited with the conclusion that its rate was previously greatly 
underestimated. Cold electrosphere, when it is radially perturbed, is 
capable of pair creation as well. I will discuss physical conditions and 
mechanisms for compact astrophysical objects to produce 
electron-positron pair outflows, as well as their observational 
consequences.
