dimHB
DimHB is a term used in the field of astrophysics to describe a class of stars that exhibit a specific type of variability in their light curves. These stars are characterized by a slow, gradual dimming of their brightness over a period of several years, followed by a more rapid recovery to their original brightness. The dimming phase is typically accompanied by a decrease in the star's effective temperature, indicating a reduction in its luminosity.
The cause of this behavior is not yet fully understood, but it is believed to be related
DimHB stars are typically found in the horizontal branch of the Hertzsprung-Russell diagram, which is a plot
