A transparent plate inserted in one of the arms of an interferometer, in particular the → Michelson interferometer, to compensate for a longer → optical path in the other arm. Its function is to ensure that the beams transverse the same total thickness of glass in both arms of the interferometer. This is not essential for producing → interference fringes in monochromatic light. The compensator plate is of the same glass and the same thickness as the → beam splitter plate.

compensator; → plate.

compete
  هاجوییدن   
hâjuyidan

Fr.: concourir, rivaliser   

To strive to outdo another for acknowledgment, a prize, supremacy, profit, etc.; engage in a contest (Dictionary.com).

M.E., from M.Fr. compéter, from L.L. competere "to strive in common," from → com- "together" + petere "to strive, go forward, seek," from PIE base *pet- "to fly, rush" (cf. Av. pat- "to fly, fall, rush," patarəta- "winged;" Mid.Pers. patet "falls," opastan "to fall;" Mod.Pers. oftâdan "to fall;" Skt. patati "he flies, falls," pátra- "wing, feather, leaf;" Gk. piptein "to fall," pterux "wing;" O.E. feðer "feather;" L. penna "feather, wing").

competitive accretion model
  مدل ِ فربال ِ هاجویشی   
model-e farbâl-e hâjuyeši

Fr.: modèle d'accrétion compétitive   

A scenario for → massive star formation whereby developing → protostars in their natal → molecular clouds compete with each other to gather mass. The protostars → accrete mass with a rate which depends on their location within the protocluster. They use the same reservoir of gas to grow. Therefore those protostars nearest the center, where the potential well is deep, and gas densities are higher, have the highest → accretion rates. The competitive accretion model explains the observational fact that the most massive stars are generally found in cluster cores. It accounts also for the distribution of stellar masses. In this model the accretion process depends on the content of the cluster. In clusters where gas dominates the potential (e.g. at initial stages of cluster formation), the accretion process is better modeled by using the → tidal radius as the accretion radius. In contrast, when the stars dominate the cluster potential and are virialized, the accretion is better modeled by → Bondi-Hoyle accretion (Bonnell et al. 1997, MNRAS 285, 201; 2001, MNRAS 323, 785).

competitive; → accretion; → model.
