All Tables

Table 1: The list of $\lambda$ Boo stars.
Table 2: Duplicity detection and measures.
Table 3: $\lambda$ Boo stars observed with the PUEO adaptive optics. The note "nothing detected'' means that there is no companion at less than 2 arcsec.
Table 4: Radial velocity and notes given in the BSC and $v\sin i$ from various sources.
Table 5: Reddening, atmospheric parameters and distance in parsec computed from the Hipparcos parallaxes. The TD1 groups described in Sect. 10 are given in the last column; " * '' indicates that the star has not been observed by this satellite "-'' is given when no visual photometry is available and " : '' when the TD1 values have a too large error to be used. We recall that HD 89 353 (HR 4049) is not considered here (see Sect. 6).
