The AGB population of NGC 6822
L. F. Sibbons, M. -R. L. Cioni, M. Irwin +1
The metallicity gradient and the stellar distribution within the Local Group dwarf galaxy NGC 6822 has been studied photometrically using asymptotic branch stars (AGB). In order to…
AGB Stars in WLM
Benjamin Tatton, Maria-Rosa Cioni, Mike Irwin
We investigate the star formation history and metallicity of the Local Group irregular dwarf galaxy WLM using wide-field JHK near-infrared imaging, spanning a region of approximate…
Ellipsoidal Variability and the Difference between Sequence D and E Red Giants
C. P. Nicholls, P. R. Wood, M. -R. L. Cioni
We have studied a sample of Large Magellanic Cloud red giant binaries that lie on sequence E in the period--luminosity plane. We show that their combined light and velocity curves…
