Abstract Introducing a new coordinate system and choosing a set of appropriate matrices $\gamma^\mu$, this paper attempts to investigate the fermion tunneling of charged particles across the event horizon from the Vaidya--Bonner de Sitter black hole. The result shows that the tunneling rate of the non-static black hole is related not only to the change of Bekenstein--Hawking entropy but also to the integral of the changing horizon, which violates unitary theory and is different from the stationary case.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
