Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Context. Although several attempts have been made to identify solar-type members on the main sequence of the nearby open cluster Coma Berenices (Mel 111), the population of the lower main sequence is still poorly known. ...
We have investigated the deposition at zero impact kinetic energy of the Ag atom and clusters (Ag/sub 7/,Ag/sub 19/) on the (100) and (111) surfaces of Pd by molecular dynamics simulations performed within the embedded atom-method scheme. Our results eluci ...
Context. The Alpha Persei open cluster (Melotte 20) is one of the nearby clusters (d < 500 pc) for which a long-term systematic radial-velocity monitoring of the solar-type stars has not been published so far. ...
We consider the effects of doping the S=3/2 kagome lattice with static, nonmagnetic impurities. By exact-diagonalization calculations on small clusters, we deduce the local spin correlations and magnetization distribution around a vacancy. As in the S=1/2 ...
A 304L stainless steel water degrader was irradiated with 800 MeV protons at Los Alamos Neutron Science Centre (LANSCE) up to 8.5 dpa at temperatures up to 250 degreesC. Tensile tests showed that hardening and embrittlement were induced in the material. In ...
The reaction I2M + hn -> I2(B) + M (M = H, N, O, I) was studied following excitation of the I2M cluster above its B state dissocn. limit. Dispersion of the I fluorescence allows for the detn. of the relative populations of a no. of the vibrational levels v ...
The many peculiarities of Ap stars (not only chemical ones, but also magnetic field and slow rotation) may vary during the main-sequence evolution of these stars. We review here briefly the evidences found in the last thirty years for such evolution, with ...
We conducted an exploratory search for quasars at z similar to 6-8, using the Early Data Release (EDR) from the United Kingdom Infrared Deep Sky Survey (UKIDSS) cross-matched to panoramic optical imagery. High-redshift quasar candidates are chosen using mu ...
We investigate how the [O II] properties and the morphologies of galaxies in clusters and groups at z = 0.4-0.8 depend on projected local galaxy density, and compare with the field at similar redshifts and clusters at low z. In both nearby and distant clus ...
We present K-band data for the brightest cluster galaxies (BCGs) from the ESO Distant Cluster Survey (EDisCS). These data are combined with the photometry published by Aragon Salamanca, Baugh & Kauffmann and a low-redshift comparison sample built from the ...
