Scientific paper

A search for chromospheric emission in the Ca II H and K lines was made for eight main-sequence A-stars in the young clusters C 0838-528 (IC 2391) and in the Hyades, where (at least later-type) stars have generally enhanced chromospheric activity, making possible emission easier to detect. No evidence for emission was found in these stars and nor in Sirius (A 1 V).
