Conti scenario
  سناریوی ِ کونتی   
senâryo-ye Conti

Fr.: scénario de Conti   

A scenario according to which the existence of peculiar → Wolf-Rayet stars could be explained by intense → mass loss that characterizes → massive stars. An → O-type star loses a significant amount of mass via → stellar winds, revealing first the CNO-burning products at its surface, and subsequently the → helium burning products. These two stages are spectroscopically identified with the → WN Wolf-Rayet and → WC Wolf-Rayet phases. A version of the scenario would be:
M> 85 Msun: O → LBV → WN → WC → SN
40 >M> 85 Msun: O → WN → WC → SN
25 >M> 40 Msun: O → RSG → WN → WC → SN
20 >M> 25 Msun: O → RSG → WN → SN
10 >M> 20 Msun: OB → RSG → BSG → SN.
The mass ranges shown are meant only to be illustrative; they are a function of → metallicity (see, e.g., Philip Massey, 2003, ARAA 41, 15).

  قاره

continental crust
  پوسته‌ی ِ اقیانوسی   
puste-ye qâre-yi (#)

Fr.: croûte continentale   

The part of the → Earth's crust which underlies the → continents. Continental crust is more silica-rich and thicker than → oceanic crust, and is on average older. However, it is highly variable in all of these respects. The average thickness of the continental crust is about 40km, but beneath parts of the Andes and the Himalaya mountain ranges the crust is more than 70 km thick. Continental crust is continuously being eroded and turned into sediment. Some of this sediment ends up on the ocean floor where it can be returned to the → Earth's mantle at → subduction zones. The oldest parts of the continental crust include some rocks that are nearly 4 billion years old. New continental crust is produced by the destruction of oceanic crust at subduction zones, a process that continues today.

continental; → crust.

continental drift
  دلک ِ قاره‌ها   
delek-e qârehâ

Fr.: dérive de continents   

A hypothesis proposed by Alfred Wegener (1912) suggesting that the → continents are not stationary, but drift through time. Wegener's hypothesis has since been developed and included in a new theory called → plate tectonics.

continental; → drift.
