The Core-Wing Anomaly of Cool Ap Stars: Abnormal Balmer Profiles
Charles R. Cowley, S. Hubrig, T. A. Ryabchikova +3
Paper by Cowley et al. The Core-Wing Anomaly Etc. The profiles of H in a number of cool Ap stars are anomalous. Broad wings, indicative of temperatures in the range 7000-8000K e…
The boron absorption line at 2089.6 AA in HD 140283 ?
P. Thoren, B. Edvardsson
We have observed the B I line at 2089.6 AA in the metal poor star HD 140283 with HST/STIS. The observation was an attempt to confirm the B abundances derived from the 2497 AA B I l…
Self-broadening in Balmer line wing formation in stellar atmospheres
P. S. Barklem, N. Piskunov, B. J. O'Mara
Details of a theory of self-broadening of hydrogen lines are presented. The main features of the new theory are that the dispersive-inductive components of the interaction (van der…
Chemical abundances in cool metal rich disk dwarf stars
P. Thoren, S. Feltzing
The present study of spectra of twelve metal-rich cool dwarf stars, carefully selected in order to cover a range of temperatures (~4400 - 6000 K), is a follow up on Feltzing & Gust…
The beryllium abundance in the very metal-poor halo star G 64-12 from VLT/UVES observations
F. Primas, M. Asplund, P. E. Nissen +1
We report on a new spectroscopic analysis of the very metal deficient star G 64-12 ([Fe/H]=-3.3), aimed at determining, for the first time, its Be content. The spectra were observe…
Results from the AMANDA High Energy Neutrino Detector
E. Andres, P. Askebjer, X. Bai +2
This paper briefly summarizes the search for astronomical sources of high-energy neutrinos using the AMANDA-B10 detector. The complete data set from 1997 was analyzed. For E_mu>10…
Modelling CO emission from Mira's wind
N. Ryde, F. L. Schoeier
We have modelled the circumstellar envelope of {\it o} Ceti (Mira) using new observational constraints. These are obtained from photospheric light scattered in near-IR vibrational-…
Magnetic Fields in the Early Universe
Dario Grasso, H. R. Rubinstein
This review concerns the origin and the possible effects of magnetic fields in the early Universe. We start by providing to the reader with a short overview of the current state of…
ISO impact on stellar models and vice versa
L. Decin, C. Waelkens, K. Eriksson +5
We present a detailed spectroscopic study of a sample of bright, mostly cool, stars observed with the Short-Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (I…
ISO-SWS calibration and the accurate modelling of cool-star atmospheres: I. Method
L. Decin, C. Waelkens, K. Eriksson +5
A detailed spectroscopic study of the ISO-SWS data of the red giant Alpha Tau is presented, which enables not only the accurate determination of the stellar parameters of Alpha Tau…
Mira's wind explored in scattering infrared CO lines
N. Ryde, B. Gustafsson, K. Eriksson +1
We have observed the intermediate regions of the circumstellar envelope of Mira (o Ceti) in photospheric light scattered by three vibration-rotation transitions of the fundamental…
Chemical composition of evolved stars in the open cluster M 67
G. Tautvaisiene, B. Edvardsson, I. Tuominen +1
High-resolution spectra of six core helium-burning `clump' stars and three giants in the open cluster M 67 have been obtained with the SOFIN spectrograph on the Nordic Optical Tele…
Removal of the calcium underabundance in cool metal rich Galactic disk dwarfs
Patrik Thoren
An apparent Ca underabundance for cool metal rich disk dwarfs was derived by Feltzing & Gustafsson (1998, A&AS, 129, 237). This was suggested to be a NLTE effect, following the pre…
Line formation in solar granulation: III. The photospheric Si and meteoritic Fe abundances
M. Asplund
Using realistic hydrodynamical simulations of the solar surface convection as 3D, time-dependent, inhomogeneous model atmospheres, the solar photospheric Si abundance has been dete…
The effects of numerical resolution on hydrodynamical surface convection simulations and spectral line formation
M. Asplund, H. -G. Ludwig, AA. Nordlund +1
The computationally demanding nature of radiative-hydrodynamical simulations of stellar surface convection warrants an investigation of the sensitivity of the convective structure…
The lithium isotope ratio in the metal-poor halo star G271-162 from VLT/UVES observations
P. E. Nissen, M. Asplund, V. Hill +1
A high resolution (R = 110.000), very high S/N (>600) spectrum of the metal-poor turnoff star G271-162 has been obtained in connection with the commissioning of UVES at VLT/Kueyen.…
