Âbi "color of water," from âb "water," Mid.Pers. âb, O.Pers./Av. âp-, Skt. âp-, PIE *âp-; → Aquarius.
blue compact dwarf galaxy
kahkešân-e kutule-ye âbi-ye hampak
Fr.: galaxie naine bleue compacte
An small → irregular galaxy undergoing → violent star formation activity. These objects appear blue by reason of containing clusters of hot, → massive stars which ionize the surrounding interstellar gas. They are chemically unevolved since their → metallicity is only 1/3 to 1/30 of the solar value. Same as → H II galaxy.
Fr.: continuum bleu
The → continuum emission of an astronomical source with wavelengths between about 492 and 455 nm.
Fr.: géante bleue
A giant star with spectral type O or B.
blue halo star
setâregân-e âbi-ye hâlé
Fr.: étoiles bleues du halo
blue HB star
Fr.: étoile BHB
Same as → blue horizontal branch star.
blue hook star
setare-ye qollab-e abi
Fr.: étoile du crochet bleu
A rare class of → horizontal branch (HB)
stars that so far have been
found in only very few Galactic → globular clusters.
These stars are such called because they
form a blue hook at the hot end of the HB in
→ far ultraviolet
(FUV) → color-magnitude diagrams.
The physical mechanism that produces blue hook populations
is still uncertain. At least two scenarios have been proposed.
blue horizontal branch star
setâre-ye âbi-ye šâxe-ye ofoqi
Fr.: étoile bleue de la branche horizontale
A member of a population of blue stars appearing on the → horizontal branch in the → Hertzsprung-Russell diagram of the Galactic → halo populations and → globular clusters. Belonging to → spectral types B3 to A0, they have evolved past the → red giant stage and are burning helium in their core.
