| Resumo: | This work has focused primarily on the analysis of infrared of 1916 red giant stars
Pinsonneault catalog. To perform this analysis we use the evaluation of the color-color
diagram as a first selection criterion looking for stars with infrared excess, of which 47
were selected stars, then we analyze the spectral energy distributions or SED where 29
stars were selected and infrared excess of confirmation, We passed the visual inspection,
where the 29 stars one, the KIC9728845 star, showed no contamination by background
galaxies or a nearby star. On visual inspection, and the SEDS analyzed over the bands
W1, W2 and W3 mainly by bands and bands W3 and W4 satellite WISE. Finally we
calculate the tempertura this dust at about 200K. |
