- An Am star or metallic-line star is a type of chemically peculiar star of spectral type A whose spectrum has strong and often variable absorption lines of metals such as zinc, strontium, zirconium, and barium, and deficiencies of others, such as calcium and scandium. The original definition of an Am star was one in which the star shows “an apparent surface underabundance of Ca (and/or Sc) and/or an apparent overabundance of the Fe group and heavier elements”.
Beholde the hyre of ye labourers which have reped doune youre feldes (which hyer is of you kept backe by fraude) cryeth: and ye cryes of them which have reped are entred into the eares of the lorde Sabaoth.
James 5:4 TYN
