Aims. A sample of of B9 to F2-type main sequence single stars has been built from highly
homogeneous parameters determined for a large sample cleansed of objects presenting the …

This work is the second part of the set of measurements of v sin i for A-type stars, begun by
Royer et al.(\cite {Ror_02a}). Spectra of 249 B8 to F2-type stars brighter than V= 7 have …

An elemental abundance analysis of Vega has been performed using high-signal-to-noise
2.4 A/mm Reticon observations of the region 4313-4809 A. Vega is found to be a metal-poor …

An extensive profile-fitting analysis of the Oi 7771–5 triplet (along with the nearby Fei line)
was carried out for thirty-one A-type stars, eighteen of them belonging to the Hyades group …

The chemical composition of the Lambda Bootis stars ADS Classic is now deprecated. It will
be completely retired in October 2019. This page will automatically redirect to the new ADS …

We analysed the light curves of a large sample of long period variables in the LMC from the
AGAPEROS catalogue. The (non) regularity of the light change is discussed in detail …

Projected rotation rates of five early A-type slowly rotating stars are measured
spectroscopically to a precision of 0.2 km s− 1. A detailed Fourier analysis is done, as well …

We have designed and constructed a second-generation version of the dispersed Fourier
transform spectrograph, or dFTS. This instrument combines a spectral interferometer with a …

Traditional line identification techniques result in the assignment of individual lines to an
atomic or ionic species (eg, Ca I, Fe il). These methods may be supplemented by …

The abundance analysis of three SI lines at 6757 Â, 6748 Â, and 6743 Â observed in HR
4049 reveals that the S overabundance derived from the SI 8694 A feature may suffer …
