Lambda Boo stars with composite spectra
R. Faraggiana, P. Bonifacio, E. Caffau +2
We examine the large sample of lambda Boo candidates collected in Table 1 of Gerbaldi et al. (2003) to see how many of them show composite spectra. Of the 132 lambda Boo candidates…
HD 174005: another binary classified as lambda Boo
R. Faraggiana, M. Gerbaldi, P. Bonifacio
We demonstrate that HD 174005, a star recently classified as belonging to the lambda Boo group, is in reality a double lined spectroscopic binary; at some phases, the observed comp…
Spectra of binaries classified as lambda Boo stars
R. Faraggiana, M. Gerbaldi, P. Bonifacio +1
High angular resolution observations have shown that some stars classified as lambda Boo are binaries with low values of angular separation and magnitude difference of the componen…
Definitions of the Lambda Boo stars
R. Faraggiana, M. Gerbaldi
Since the identification of these stars by Morgan et al. in 1943, various definitions have been proposed for the stars of the Lambda Bootis group. We present here the various defin…
Determination of T_eff and log g for A0 type stars and its impact on the interpretation of the HR diagram with the HIPPARCOS results
M. Gerbaldi, R. Faraggiana, R. Burnage +3
The determination of the ``Fundamental Parameters'' T_eff and log g for a set of dwarf A0-type stars is discussed in terms of consistency when comparing these values determined thr…
