Theoretical expectations for clump red giants as distance indicators
Leo Girardi
Variations of ~0.4 mag are expected in the I-band absolute magnitude of red clump giants, M_I^RC, as a function of both stellar age and metallicity. This regardless of some potenti…

Broad-band colour evolution of star clusters
Leo Girardi
We briefly review the main features in the broad-band colour evolution of star clusters, over the complete age interval from 10^7 to 10^(10) yr. The emphasis is in the problem of a…

On the peculiar red clump morphology in the open clusters NGC 752 and NGC 7789
L. Girardi, J. -C. Mermilliod, G. Carraro
The red clump stars in the open cluster NGC 752 present a peculiar distribution in the colour-magnitude diagran (CMD): the clump is observed to present a faint extension, slightly…
