Of or relating to → convection.
Fr.: cellule convective
Fr.: nuage convectif
Meteorology: A cloud that owes its vertical development, and possibly its origin, to convection.
Fr.: cœur convectif
Fr.: enveloppe convective
1) A → convective zone situated beneath the surface
of solar type stars.
Fr.: dépassement convectif
In a → massive star, penetration of the upper layers of the → convective core into the → radiative zone due to → turbulence effects. The enlargement of the convective core results in more luminous stars in theoretical models.
Fr.: tourbillon convectif
Fr.: zone convective
A zone inside a star in which → convection takes place; the central → core in → massive stars and the zone underneath → photosphere in low mass stars like the Sun. Recent works predict the presence of a thin convection zone in sufficiently massive main sequence stars which originates from the iron opacity and partial helium ionization. See also → iron convection zone.
