The light curves of the short–period variable stars in the Carina dwarf Spheroidal galaxy
The light curves of the high–amplitude, short– period variable stars discovered by Mateo et al. (1998) in the Carina dwarf Spheroidal Galaxy were re-analyzed to refine their properties and compare them with those of galactic stars. In spite of a different pulsation mode established by means of different PLM relationships, the Fourier parameters did not reveal a separation between the two groups...
متن کاملWfpc2 Observations of the Carina Dwarf Spheroidal Galaxy
We present our analysis of Hubble Space Telescope Wide Field Planetary Camera 2 observations in F555W (∼V ) and F814W (∼I) of the Carina dwarf spheroidal galaxy. The resulting V vs V−I color-magnitude diagrams reach V ≈27.1 mag. The reddening of Carina is estimated to be E(V−I) = 0.08±0.02 mag. A new estimate of the distance modulus of Carina, (m − M)0 = 19.87±0.11 mag, has been derived primari...
متن کاملEpisodic Star Formation in the Carina Dsph Galaxy
B, R photometry for stars in the Carina dwarf spheroidal galaxy (dSph) that is unprecedented in depth, accuracy and spatial coverage demonstrates that it has had a surprisingly complex evolution dominated by episodic bursts of star formation. Comparing the color-magnitude diagram (CMD) with new theoretical isochrones, we determine that the ages of the \bursts" are approximately 2, 3{6, and 11{1...
متن کاملSearch for variable stars in the Carina dSph galaxy
We discuss methods and preliminary results in a search for variable stars in the Carina dSph galaxy. This galaxy presents a complex star formation history and hosts a unique sample of variable stars. We collected B,V time series data during different runs, from 1999 to 2004, with the MOSAICII camera available at 4m CTIO telescope. The methodology is based on correlations between a version of th...
متن کاملVariable Stars in the Fornax Dwarf Galaxy
We have surveyed a 40' X 40' field. We have obtained 20 epochs with the MACHO camera (filters VyiRu) on the 1.3-m telescope (Mt Stromlo) and 15 VI epochs on the 1-m telescope at Siding Spring, over a time interval of five months. To look for variables, we used the method proposed by Welch & Stetson (1993). The variability index Jws is plotted in Fig. 1. Non-variable stars cluster around 0. The ...
