Abstract:
The Asiago photographic archive has been searched for plates
containing the symbiotic stars Hen 2-468, QW Sge, LT Del, V407 Cyg,
K 3-9, V335 Vul, FG Ser and Draco C-1. A total of 635 plates imaging
the program stars have been found and the brightness estimated using
the Henden & Munari (2000A&AS..143..343H) UBV(RI) photometric
sequences. These historical data have allowed for the first time the
determination of the orbital periods of Hen 2-468 (774 days) and
QW Sge (390.5 days), a significant improvement in the orbital period
of LT Del (465.6 days) and for V407 Cyg an evaluation of the Mira's
pulsation period and complex lightcurve shape in the red (R and I
bands). Some previously unknown outbursts have been discovered too.
