The carbon-rich type Ic SN 2007gr: the photospheric phase

S. Valenti, N. Elias-Rosa, S. Taubenberger +20

The first two months of spectroscopic and photometric monitoring of the nearby type Ic SN 2007gr are presented. The very early discovery (less than 5 days after the explosion) and…

The Afterglows of Swift-era Gamma-Ray Bursts. I. Comparing pre-Swift and Swift era Long/Soft (Type II) GRB Optical Afterglows

D. A. Kann, S. Klose, B. Zhang +73

We have gathered optical photometry data from the literature on a large sample of Swift-era gamma-ray burst (GRB) afterglows including GRBs up to September 2009, for a total of 76…

Ultra-high energy Neutrinos from Centaurus A and the Auger hot spot

Alessandro Cuoco, Steen Hannestad

The Pierre Auger collaboration has reported a correlation between Ultra-High Energy Cosmic Rays (UHECR) and nearby Active Galactic Nuclei (AGNs) within 75 Mpc. Two of these events…

Stroemgren metallicity calibration: the m1, b-y relation

A. Calamida, G. Bono, P. B. Stetson +15

We performed a new calibration of the Stroemgren metallicity index m1 based on the b-y color of cluster red giant stars. The current Metallicity-Index-Color relation is not linear…

Inter-comparison of the g-, f- and p-modes calculated using different oscillation codes for a given stellar model

A. Moya, J. Christensen-Dalsgaard, S. Charpinet +9

In order to make astroseismology a powerful tool to explore stellar interiors, different numerical codes should give the same oscillation frequencies for the same input physics. Th…

An abundance analysis of bright giants in the globular cluster NGC 1851

David Yong, Frank Grundahl

We present the chemical compositions for eight bright giants in the globular cluster NGC 1851. Our analysis reveals large star-to-star abundance variations and correlations of the…
