Hydrogen-Line Profiles of Some λ Bootis Stars
Published online by Cambridge University Press: 12 April 2016
Abstract
The observed hydrogen-line profiles of four λ Boo type stars— HD 111786, HD 125162, HD 179791 and HD 192640 are presented. Existence of two separate groups based on the shape of these lines is confirmed. Radial velocity (Vr = −5 ± 3 kms−1) and projected rotational velocity (vsini = 130 ± 10 kms−1) for HD 111786 are measured.
