Abstract
JL 82 is a known binary, consisting of an sdB star and a companion which is not directly
observable in the optical. Photometric measurements reported in this paper show it to variable
with both the binary period (∼0.75 d), as well as on much shorter time-scales. The shorter
periods are ascribed to pulsation of the sdB star, making it a member of the PG 1716 class of
pulsating stars.
