Abstract:
We search for photometric variability in chemically peculiar A type
stars in the northern hemisphere. High-speed photometric observations
of Ap and Am star candidates have been carried out from ARIES (Manora
Peak, Nainital) using a three-channel fast photometer attached to the
ARIES 104-cm Sampurnanand telescope.
Description:
For the Nainital-Cape Survey, high-speed photometric observations of
Ap and Am star candidates are carried out from ARIES (Manora Peak,
Nainital) using a three-channel fast photometer attached to the ARIES
104-cm Sampurnanand telescope.
