Lambda Boötis star
(λ Boo)
(peculiar star with metallicity only with lighter elements)
A Lambda Boötis star (λ Boo)
is a chemically peculiar star, apparently a
Population I star, generally A-type. with
carbon, oxygen, and nitrogen metallicity much
like the Sun, but with much less iron or heavier elements.
Lambda Boötis (λ Boötis) is the prototype.
On the order of 50-100 are known.
There is no consensus explanation:
theories include attributes of the star-forming region,
or accretion of less-iron-rich gas after formation.
