Mass-Loss in the Late Stage of Stellar Evolution:
III. AGB Stars in the Magellanic Clouds Star Clusters
<=== abstract ===>
SCIENTIFIC ABSTRACT
The lack of the realistic mass-loss formula has been the main cause of the
uncertainty in the theory of the stellar evolution. With known distances,
metallicities and with a wide range of age, the star clusters in the
Magellanic Clouds offer a unique opportunity to understand the role of mass-
loss in the late stage of stellar evolution.
We propose here to measure the infrared excess of individual AGB stars in
these clusters. For the first time, the reliable mass-loss rate will be
obtained along the AGB sequence of low to intermediate mass stars.
A crucial test of the evolutionary calculation will be given by the comparison
between the mass-loss rates derived from these observations and the mass-loss
formula assumed in the theory.
OBSERVATION SUMMARY
CAM images with a PFOV of 3" will be taken for the rich stellar clusters in
the Magellanic Clouds using three LW filters, LW1, LW2, and LW10.
The expected signal to noise ratios are about 11 at 4.5 microns (LW1), 14 at
6.75 microns (LW2), and 7 at 11.5 microns (LW10), respectively for flux levels
of 1 mJy, i.e., of bright AGB stars. Since 4 to 9 frames are needed to cover
an individual cluster, a raster scan mode will be applied to each cluster.
The scan direction is the spacecraft y axis.
As an additional program, LINKED Observations with PHOT-P are proposed.
Photometry at 25 microns through 23" aperture and at 60 microns through 52"
aperture will be done for 5 brightest AGB stars in NGC 1783 and NGC 419,
respectively, found in the course of CAM observations. Expected signal
to noise ratios are about 9 at 25 microns for flux level of 50 mJy and 4 at
60 microns for flux level of 10 mJy with 128 sec. integration time.
CONCATENATION:
In order to obtain accurate color-color and color-magnitude diagram, CAM
observations of each cluster with three filters should be concatenated because
AGB stars often show variabilities.
LINKED OBSERVATIONS:
It is expected that very red, heavily obscured AGB stars will be found in the
CAM observations. Since these stars may have great importance in understanding
the mass-loss phenomenon itself and its effects on the late stages of stellar
evolution, we propose to observe them photometrically with PHOT-P 25 and 60
micron bands. From CAM observations, we will select 5 infrared brightest
stars in NGC 1783 and NGC 419, respectively, for this purpose. As the
positions of these stars are not known in advance, the PHOT observations (OSN
4-8, 12-16) have to be linked to the CAM observations. Photometry should be
carried out in several orbits after the CAM observations.
