| Abstract: |
Recent large-scale time-series surveys provide us with
homogeneous datasets which are useful for
investigating systematics of variations of classical Cepheids.
Combining our near-infrared (JHKs) catalogue with
the OGLE-III optical (VI) counterpart, we here discuss
the light curves of classical Cepheids in the Small Magellanic Cloud
in these wavelengths.
The shapes of the light curves show a systematic trend
varying with the wavelength and with the period.
These systematic characteristics can be explained by
simple arithmetic
considering the bolometric correction and underlying variations of
temperature and radius of Cepheids. |
