Fr.: 1) reconnaissance, aveu; 2) remerciement
1) Recognition of the existence or truth of something.
Fr.: modèle de Cowling
A model of the internal structure of → massive stars in which a → convective core is surrounded by a large → radiative envelope. However, recent studies point to the presence of a thin → convection zone in the outer envelope of hot massive stars, beneath the → photosphere, which is caused by opacity peaks associated with iron and helium ionization. See also → iron convection zone.
After Thomas Cowling (1906-1990), a British astronomer, who put forward the model; → model.

joqd (#), buf (#)
Fr.: hibou, chouette
Any of an order (Strigiformes) of chiefly nocturnal birds of prey with a large head and eyes, short hooked bill, strong talons, and soft fluffy often brown-mottled plumage (Merriam-Webster.com).
Owl, from O.E. ule, from P.Gmc. *uwwalon (cf. Du. uil, O.H.G. uwila, Ger. Eule), a diminutive of root *uwwa, which is imitative of an owl's hoot (cf. L. ulula "owl;" Gk. ololyzein "to cry aloud," Skt. uluka- "owl."

miq-e buf, ~ joqd
Fr.: Nébuleuse de la Chouette
A → planetary nebula in the constellation → Ursa Major, one of the four planetary nebulae in → Messier catalog. It is one of the more complex planetary nebulae known. Its appearance has been interpreted as that of a cylindrical torus shell viewed obliquely, so that the projected matter-poor ends of the cylinder correspond with the Owl's eyes. Also known as M97 or NGC 3587.
Slowly Pulsating B star (SPB)
setâre-ye âhesté tapande-ye gune-ye B
Fr.: étoile B pulsante à longue période
A member of a class of → B stars that are situated along the → main sequence with → spectral types ranging from B2 to B9 and masses from 3 to 7 → solar masses. In the → H-R diagram the SPB group lies below → beta Cephei variables, which are more massive. SPBs show light and line-profile variations that are multi-periodic with periods of the order of days. This variability is understood in terms of non-radial → stellar pulsations, and their → oscillation modes are high-order → g modes. Theoretical models attribute the pulsational nature of SPBs to the → kappa mechanism, acting in the metal → opacity bump at 2 x 105 K. Their g-mode pulsations penetrate deep into the stellar interior, making these objects very promising for → asteroseismology. Several oscillation modes are excited simultaneously, resulting in periodicities on time scales of the order of months or even years. The prototype of this group is 53 Per. First introduced as a distinct class by Waelkens (1991, A&A 246, 453).
