We present light curves for 12 variable stars identified in the newly discovered satellite of the Milky Way in the Bootes constellation (Belokurov et al. 2006).Our sample inc…
Infrared photometry of Cepheids in the LMC clusters NGC 1866 and NGC 2031
Vincenzo Testa, Marcella Marconi, Ilaria Musella +6
Near infrared (IR) studies of Cepheid variables in the LMC take advantage of the reduced light curve amplitude and metallicity dependence at these wavelengths. This work presents s…
