An empirical mass-loss law for Population II giants from the Spitzer-IRAC survey of Galactic globular clusters
L. Origlia, F. R. Ferraro, S. Fabbri +4
The main aim of the present work is to derive an empirical mass-loss (ML) law for Population II stars in first and second ascent red giant branches. We used the Spitzer InfraRed Ar…
Dust is forming along the red giant branch of 47 TUC
Livia Origlia, Robert T. Rood, Sara Fabbri +4
We present additional evidence that dust is really forming along the red giant branch (RGB) of 47 Tuc at luminosities ranging from above the horizontal branch to the RGB-tip (Origl…
Probing the Galactic Bulge with deep Adaptive Optics imaging: the age of NGC 6440
L. Origlia, S. Lena, E. Diolaiti +4
We present first results of a pilot project aimed at exploiting the potentiality of ground based adaptive optics imaging in the near infrared to determine the age of stellar cluste…
The First Empirical Mass Loss Law for Population II Giants
Livia Origlia, Robert T. Rood, Sara Fabbri +3
Using the Spitzer IRAC camera we have obtained mid-IR photometry of the red giant branch stars in the Galactic globular cluster 47 Tuc. About 100 stars show an excess of mid-infrar…
