    Quantum-gravitational effects on gauge-invariant scalar and tensor perturbations during inflation: The de Sitter case

    Full text link
    We present detailed calculations for quantum-gravitational corrections to the power spectra of gauge-invariant scalar and tensor perturbations during inflation. This is done by performing a semiclassical Born-Oppenheimer type of approximation to the Wheeler-DeWitt equation, from which we obtain a Schroedinger equation with quantum-gravitational correction terms. As a first step, we perform our calculation for a de Sitter universe and find that the correction terms lead to an enhancement of power on the largest scales.Comment: 21 pages, 5 figures, clarifications and references added, version accepted for publication in Physical Review

    Thermal Evolution and Core Formation on Asteroid 4 Vesta in the Magma Ocean Regime

    Geochemical observations of the eucrite and diogenite meteorites, together with observations made by NASAs Dawn spacecraft while orbiting asteroid 4 Vesta, indicate that Vesta has differentiated to form a crust, mantle, and core. Eucrite and diogenite petrology is best explained by solidification of the crust from a magma ocean constituting 60-70% of Vestas silicates [3], or a temperature of ~1550 C. The abundances of moderately siderophile elements (Ni, Co, Mo, W, and P) in eucrites require that essentially all of the metallic phase in Vesta segregated to form a core prior to eucrite formation and likely reached a temperature of 1450- 1575 C. These observations provide important constraints on Vestas thermal evolution. The high inferred temperature indicates that convective heat transport must have been important during part of Vestas thermal evolution. In this study, we model Vestas thermal evolution in the magma ocean regime

    Le diagnostic a Ă©tĂ© rĂ©alisĂ© sur un terrain concernĂ© par l’ouverture d’une carriĂšre par la SociĂ©tĂ© Forloc. Elle aura pour vocation l’exploitation des sĂ©diments d’une butte hĂ©ritĂ©e du Tertiaire. La premiĂšre tranche vise Ă  exploiter 3,5 ha. Les sondages qui ont couvert plus de 10 % de l’emprise, ont seulement mis au jour quelques vestiges fugaces de la premiĂšre guerre mondiale et ses restes de pilonnage (cratĂšre d’obus, obus non explosĂ©)

    Identifiant de l'opĂ©ration archĂ©ologique : 9268 Date de l'opĂ©ration : 2007 (EX) Le site « Les Rossignols » Ă  Saint-Just-en-ChaussĂ©e, mis au jour en 1994-1995 au cours de diffĂ©rentes interventions, menĂ©es par Georges-Pierre Woimant, a rĂ©vĂ©lĂ© des occupations depuis La TĂšne finale (D1-D2) jusqu’au Haut-Empire. Les vestiges les plus remarquables Ă©taient des fossĂ©s remplis d’ossements de chevaux avec des piĂšces de char et d’harnachement. Quelques os humains y Ă©taient mĂȘlĂ©s. Des similaritĂ©s avec le..

    Identifiant de l'opĂ©ration archĂ©ologique : 9160 Date de l'opĂ©ration : 2007 (EX) Une clinique vĂ©tĂ©rinaire s’implante sur 3 000 m2 sis le boulevard de l’Esches dans une ZAC au sud de la commune de MĂ©ru. La mise en Ɠuvre de la construction nĂ©cessitera le retrait des remblais qui couvrent la majoritĂ© de l’emprise et ses fondations seront au contact de niveaux offrant un potentiel archĂ©ologique non nĂ©gligeable. En effet, la richesse archĂ©ologique de cette ville, a Ă©tĂ© dĂ©montrĂ©e par de nombreuses..

    L’amĂ©nagement d’une usine sur la commune de Nesle a motivĂ© une prescription de sondages archĂ©ologiques prĂ©alables, sur une superficie de 63 496 m2. L’emprise se situe au sommet d’un versant qui domine la vallĂ©e de l’Ingon, riviĂšre affluente de la Somme. La parcelle est traversĂ©e par un palĂ©ovallon, totalement comblĂ©, ancien affluent de la riviĂšre. Le substrat gĂ©ologique est matĂ©rialisĂ© par une couverture tertiaire. Celle-ci est reprĂ©sentĂ©e par des sables gris sus-jacent un niveau de galets Ă  ..
