A prefix meaning "copper," used in the formation of compound words.
From Gk. chalko-, combining form of chalkos "copper."
Xalco-, loan from Gk., as above.
vine-ye hamafzudé, tasvir-e ~
Fr.: image intégrée
An image made up of several individual images of relatively short exposure times which are added together in order to produce a final image of higher quality.
Co-added, from → co- "together" + added p.p. of → add; → image.
Tasvir, → image; hamafzudé from ham- "together", → com-, + afzudé p.p. of afzudan, → add.
Fr.: théorie de co-formation
A theory according to which the Earth and Moon formed from the → protoplanetary disk at the same time. See also → giant impact hypothesis, → capture theory, → fission theory.
Of or relating to two or more celestial bodies that share, or almost share, the same orbit.
Fr.: mouvement co-orbital
The motion of two or more bodies around the Sun on different orbits when it takes them the same amount of time to complete one revolution. There are three possible types of co-orbital motions of a small body associated with a planet: → tadpole orbits, → horseshoe orbits, and → quasi-satellite orbits.
→ co-orbital; → motion.
mâhvâre-ye ham-madâr, bandevâr-e ~
Fr.: satellite co-orbital
Any of satellites which either share the same orbit or which occupy immediately adjacent orbits that change periodically as the satellites approach one another (Ellis et al., 2007, Planetary Ring Systems, Springer).
→ co-orbital; → satellite.
Fr.: co-orbitage; c-orbitant, co-orbiteur
The action or quality of a → co-orbiting asteroid.
From co- "together," → com- + → orbit + → -ing.
From ham- "together," → com- + madâr→ orbit + -i noun suffix.
Fr.: astéroïde co-orbiteur
An asteroid having a → co-orbital motion.
→ co-orbiting; → asteroid.
co-rotational limit (CoRol)
Fr.: limite co-rotationnelle
For any rotating planetary body, a thermal limit beyond which the → rotational velocity at the equator intersects the → Keplerian orbital velocity. Beyond this corotation limit, a hot planetary body forms a structure, called a → synestia, with a corotating inner region connected to a disk-like outer region. Beyond this limit a body cannot have a single → angular velocity. It can instead exhibit a range of morphologies with disk-like outer regions. The (CoRoL is a function that depends upon the composition, thermal state, → angular momentum and mass of a body (Simon J. Lock nd Sarah T. Stewart, 2017, arXiv:1705.07858v1).
→ co-; → rotational; → limit.
com-, col-, con-, cor-, co-
ham- (#), han- (#), hâ- (#), ha- (#)
Fr.: com-, col-, con-, cor-, co-
Prefix denoting "together; with; joint; jointly". It is sometimes used for intensification as in complete, complain, convince.

A combining form meaning "house, household, environment, nature, natural habitat."
Ultimately from Gk. oikos "house," cognate with L. villa "country house, farm," related to vicus "village, group of houses; " cf. Av. vis- "homestead, community;" O.Pers. viθ- "house, royal house, farm;" Mid.Pers. wis "village;" dialectal Pers. wiš-, vīš- "to set (of Sun)," wīs- "to enter" (Cheung 2007); Skt. viś- "settlement, house, tribe, people;" Goth. weihs "village;" Lith. viešpats "master of the house;" PIE *ueik'- "to settle (down)."
Bum-, from bum "region, land, a mansion or place where one dwells in saftey; nature, disposition;" Mid.Pers. bûm "land, earth, country;" O.Pers. būmi- "place of being/living, land, region;" Av. būmī- "earth," from bav- "to be, become, take place;" cf. Skt. bhūmi- "land, region;" PIE *bheu- "to be, come into being, become" (cf. Gk. phu- "become," phuein "to bring forth, make grow;" L. fui "I was" (perf. tense of esse), futurus "that is to be, future;" Ger. present first and second person sing. bin, bist; E. to be; O.Ir. bi'u "I am;" Lith. bu'ti "to be;" Rus. byt' "to be").
hamafzâyeš-e vinehâ, ~ tasvirhâ

A prefix denoting 10-12.
From It. piccolo "small."
