moving group
  گروه ِ جنبنده   
goruh-e jonbandé

Fr.: groupe mobile   

A young → stellar population that shares a common space motion. A moving group remains kinematically distinct within the general field stars at ages < 1 billion years, before being dispersed. As progenitor gas is cleared by OB star winds, and the natal cluster expands, stars with sufficiently high velocities become unbound and form a young, coeval moving group, possibly leaving behind a bound open cluster. Because of their common origin, moving group members have a shared age and composition. The nearest moving group is the → TW Hydrae association.

moving; → group.

MRN dust model
  مدل ِ MRN   
model-e MRN

Fr.: modèle MRN   

A model concerned with the distribution in size of → interstellar grains to account for observations of → interstellar extinction from 0.11 μm to 1.0 μm.

MNR, the initials of authors J. S. Mathis, W. Rumpl, and K. H. Nordsiek (1977, ApJ 217, 425), who introduced the mode; → dust; → model.

Mu Cephei
  مو-کفءوس

Fr.: μ Cephei   

A → red supergiant star in the → constellation → Cepheus. It is one of the largest and most luminous stars known in the → Milky Way. μ Cephei appears garnet red and is given the → spectral type of M2 Ia. The star may even be the largest star visible to the → naked eye with an estimated radius of 1.15 billion kilometres. If it replaced the Sun, it would extend beyond the orbit of Saturn. Some of its → physical parameters are: mass = 15 Msol; → radius = 1650 Rsol; → luminosity = 60 x 104 Lsol; → effective temperature = 3690 K. Also called Herschel's → Garnet star.

Cephei, genitive of → Cepheus.

mule
  استر   
astar (#)

Fr.: mulet   

The → sterile offspring of a female horse and a male donkey.

M.E., from O.E. mul, from O.Fr. mul "mule, hinny," from L. mulus "a mule," probably from a pre-Latin Mediterranean language.

Astar, from Mid.Pers. astar, ultimately from *asa-tara-, literally "horse related," from *asa- variant of aspa-, → horse, + -tara- a suffix of relation and comparative adjectives; cf. Skt. asvátara- "mule."

multi-
  بس-   
bas- (#)

Fr.: multi-   

A combining form meaning "many, much, multiple, many times, more than one, more than two, composed of many like parts, in many respects."

From L. multus "much, many," from PIE base *mel- "strong, great, numerous;" cf. L. melior "better," Gk. mala "very, very much."

Bas-, from bas "many, much;" Mid.Pers. vas "many, much;" O.Pers. vasiy "at will, greatly, utterly;" Av. varəmi "I wish," vasô, vasə "at one's pleasure or will," from vas- "to will, desire, wish."

  بس-هاوشانی، بس-هاوشان‌مندی   
bas-hâvešâni, bas-hâvešânmand

Fr.: multidisciplinaire   

Of an approach or study that juxtaposes disciplinary perspectives, adding breadth and available knowledge, information, and methods. The involved disciplines speak as separate voices in encyclopedic alignment. The status quo is not interrogated, and disciplinary elements retain their original identity. See also → interdisciplinary and → transdisciplinary (Thompson Klein, J. 2010, Creating Interdisciplinary Campus Culture, John Wiley and Sons, Inc.).

multi-; → disciplinary.

multiplanet system
  راژمان ِ بس-سیاره‌ای

multiple
  بستا، بستایی

Consisting of, having, or involving several or many individuals, parts, elements, etc.
Math.: A number that contains another number an integral number of times without a remainder: 25 is a multiple of 5.

Bastâ-, from bas "many, much" (Mid.Pers. vas "many, much;" O.Pers. vasiy "at will, greatly, utterly;" Av. varəmi "I wish," vasô, vasə "at one's pleasure or will," from vas- "to will, desire, wish") + "fold, plait, ply; piece, part," also a multiplicative suffix; Mid.Pers. tâg "piece, part."

multiple exposures
  نورداد ِ بستایی   
nurdâd-e bastâyi

multiple scattering
  پراکنش ِ بستایی   
parâkaneš-e bastâyi

Fr.: diffusion multiple   

A process of → radiative transfer in which more than one → scattering event may be of importance before → transmission, → reflection, or → absorption. In → radiation-driven winds photon scattering can take place in different → spectral lines. Each scattering occurs in a different spectral line, and successive scatterings occur at lower energies (longer wavelength). The standard theory of line driving (→ CAK model) assumes that photons can be scattered only once in the wind, which is a reasonable assumption for normal → O stars. In → Wolf-Rayet stars, where photons evolve in an atmosphere with a strong → ionization stratification, multiple scattering is important. Indeed the strength of W-R winds appears to exceed the single scattering limit.

multiple; → scattering.

multiple star

setâre-ye bastâyi

Fr.: étoile multiple   

A star which appears single but is in fact composed of more than two components. See also → multiple star system; → binary star; → triple star.
