Abstract:
This article presents the study of the light curves extracted from the
MACHO database of a sample of stars observed by the Infrared Space
Observatory in the Small Magellanic Cloud. These stars belong to the
ISO Mini-Survey catalogue of the Magellanic Clouds (ISO MCMS, Loup et
al., in preparation). Most of them are in the asymptotic giant branch
(AGB) and supergiant phases. The dominant period and amplitude of
pulsation have been derived and the stars have been classified as Mira
or Semi Regular pulsators.
Description:
Table1.dat lists the MACHO counterparts of the ISO-MCMS sources.
Table4.dat provides the DENIS, 2MASS and ISO magnitudes of the LPVs
with an ISO counterpart in the SMC. It also indicates the absolute
bolometric magnitude and the parameters that characterize the periodic
variation such as: period and amplitude. There is a flag that
indicates the type of light-curve and a factor that indicates the
quality of the period determination.
