The Metallicity dependence of the Cepheid Period-Luminosity relation: methodology and results
Marta Mottini, Martino Romaniello, Francesca Primas +3
We present the results of an observational campaign undertaken to assess the influence of the iron content on the Cepheid Period-Luminosity relation. Our data indicate that this de…
The Effect of Metallicity on the Cepheid Period-Luminosity Relation
Martino Romaniello, Francesca Primas, Marta Mottini +1
We present preliminary results of an observational campaign devoted at establishing the influence of chemical composition on the Cepheid Period-Luminosity relation. The data are in…
Determining the Metallicity of Cepheid Stars in the SMC, LMC and the Galaxy
M. Mottini, F. Primas, M. Romaniello +1
The Cepheid Period-Luminosity relation is unquestionably one of the most powerful tools at our disposal for determining the extragalactic distance scale. While significant progress…
HST study of the Stellar Populations within 30 pc of SN 1987A
Martino Romaniello, Nino Panagia, Salvatore Scuderi
We have studied the stellar populations in a region of 30 pc around SN 1987A in the Large Magellanic Cloud using multi-band HST-WFPC2 images. The effective temperature, luminosity…
