Abstract:
We present a CFH12K survey of the carbon stars in NGC 205 and its
surrounding field. We find that the number of C stars in NGC 205 is
low (∼500) for its luminosity and that very few C stars are seen
outside of the 10 isophote, suggesting tidal stripping by M31. Their
<MI≥-4.54, a magnitude nearly identical to what has been found in
other galaxies with numerous C stars. Stars with accurate (R-I)
photometry, to I∼22.5, are used to determine the outer profile of
NGC 205.
Description:
The results are based on images obtained with the CFH12K mosaic in
2000 September. The camera consists of a 12000x8000 pixel mosaic
covering a field of 42'x28', each pixel corresponding to 0.206". Images
were obtained through Mould I (2x400s) and R (3x400s) filters
and CN (3x700s) and TiO (3x700s). In spite of very good seeing
(0.8"), sky conditions during the observations were nonphotometric.
