C stars in Wolf-Lundmark-Melotte galaxy
Listed in IVOA Registry (Virtual Observatory)
We used the CFH12K wide field camera to survey the carbon star population of the Wolf-Lundmark-Melotte system using the CN-TiO technique. 149 C stars are identified with a mean <I>=20.28, corresponding to <M_I_>=-4.65, a mean luminosity similar to what we found in other irregular galaxies.
Description
Star counts in and around the main body of WLM reveal that its stellar distribution is quite elliptical ({epsilon}=0.58) with major and minor axes of 26' and 11'.
Comparison of the density profile of C stars and old red giants shows that their scale lengths differ by only 15% pointing to mixed populations. Wolf-Lundmark-Melotte is found to be unique among dwarf irregular galaxies by having essentially a handful of early-type AGB M stars thus leading to an extreme C/M ratio.
