First stars VI - Abundances of C, N, O, Li, and mixing in extremely metal-poor giants. Galactic evolution of the light elements
M. Spite, R. Cayrel, B. Plez +11
We have investigated the poorly-understood origin of nitrogen in the early Galaxy by determining N abundances in 35 extremely metal-poor halo giants (22 stars have [Fe/H]<-3.0) usi…
Tomography of the atmosphere of long-period variable stars
A. Jorissen, M. Dedecker, B. Plez +2
This paper reviews the results obtained so far with the newly developed tomographic technique, which probes the velocity field across the atmosphere of long-period variable (LPV) s…
Elemental abundances of metal poor carbon rich lead star: CS29497-030
T. Sivarani, P. Bonifacio, P. Molaro +12
We present here the abundance analysis of a metal poor carbon rich lead star, CS29497-030. High resolution and high signal to noise spectra were obtained using the UVES spectrograp…
R-process pattern in the Very-Metal-Poor Halo Star CS31082-001
V. Hill, B. Plez, R. Cayrel +1
The very-metal-poor halo star CS31082-001 was discovered to be very strongly r-process-enhanced during the course of a VLT+UVES high-resolution follow-up of metal-poor stars identi…
The formation of G-band bright points. I: Standard LTE modelling
D. Kiselman, R. J. Rutten, B. Plez
Assuming LTE, we synthesise solar G band spectra from the semiempirical flux-tube model of Briand Solanki (1995). The results agree with observed G-band bright-point contrasts with…
Envelope tomography of long-period variable stars: I. The Schwarzschild mechanism and the Balmer emission lines
R. Alvarez, A. Jorissen, B. Plez +2
This paper is the first one in a series devoted to the study of the dynamics of the atmospheres of long-period variable stars. Results from a two-month-long monitoring of the Mira…
