Abstract:
Accurate BV(RI)c light and colour curves of the Mira variable in the
dust-free symbiotic system K4-46 are presented and discussed. They
cover several consecutive pulsations cycles. The Mira mean period is
284.2d, the reddening sums to E(B-V)=0.35 and the distance is 10kpc.
Absolute spectrophotometry at both maximum and minimum brightness of
the Mira is presented.
Description:
BVRcIc CCD photometric observations were obtained with a 0.30-m Meade
RCX-400 f/8 Schmidt-Cassegrain telescope located in Cembra (Trento,
Italy).
