New λ Bootis stars with a shell.

HAUCK B., BALLEREAU D. and CHAUVILLE J.

Abstract (from CDS):

We publish here the second part of our spectroscopic survey at high dispersion of some known and suspected λ Bootis stars with a view to detecting circumstellar shell features. Eight stars of our sample exhibit such features. These stars are fast rotators, a result which is in line with Hohlweger and Rentzsch-Holm's study (1995A&A...303..819H). The analysis of the photometric data has allowed us to confirm the exclusion of a few stars misclassified from the λ Bootis group.
