Disentangling the Hercules stream

T. Bensby, M. S. Oey, S. Feltzing +1

Using high-resolution spectra of nearby F and G dwarf stars, we have investigated the detailed abundance and age structure of the Hercules stream. We find that the stars in the str…

The Lorentz force in atmospheres of CP stars: Aurigae

D. Shulyak, G. Valyavin, O. Kochukhov +7

Several dynamical processes may induce considerable electric currents in the atmospheres of magnetic chemically peculiar (CP) stars. The Lorentz force, which results from the inter…

Chemical Abundance Analysis of the Extremely Metal-Poor Star HE 1300+0157

Anna Frebel, John E. Norris, Wako Aoki +5

We present a detailed chemical abundance analysis of HE 1300+0157, a subgiant with [Fe/H]=-3.9. From a high-resolution, high-S/N Subaru/HDS spectrum we find the star to be enriched…

Pulsation in the atmosphere of the roAp star HD 24712. I. Spectroscopic observations and radial velocity measurements

T. Ryabchikova, M. Sachkov, W. W. Weiss +10

We have investigated the structure of the pulsating atmosphere of one of the best studied rapidly oscillating Ap stars, HD 24712. For this purpose we analyzed spectra collected dur…

Chemical Homogeneity in Collinder 261 and Implications for Chemical Tagging

G. M. De Silva, K. C. Freeman, M. Asplund +3

This paper presents abundances for 12 red giants of the old open cluster Collinder 261 based on spectra from VLT/UVES. Abundances were derived for Na, Mg, Si, Ca, Mn, Fe, Ni, Zr an…

Five years of searches for point sources of astrophysical neutrinos with the AMANDA-II neutrino telescope

A. Achterberg

We report the results of a five-year survey of the northern sky to search for point sources of high energy neutrinos. The search was performed on the data collected with the AMANDA…
