FG Sagittae as a New R Coronae Borealis Variable
Abstract
The 1992--93 dimming of FG Sagittae can be interpreted as a blue type R CrB decline. This favors the final flash scenario of the R CrB behavior and clears up the evolutionary connection between the planetary nebula nuclei and the R CrB phenomenon.
