Two new variable sdB stars, HE 0218−3437 and LB 1516
(Oxford University Press, 2010)
We present photometry which shows that two known hot subdwarf stars, HE 0218−3437 and
LB 1516, are variable. LB 1516 exhibits several frequencies in the range 12–25 cycles d−1
(periods of about 1–2 h) with amplitudes ...
