Continuously sheared granular matter reproduces in detail seismicity laws
S. Lherminier, R. Planet, V. Levy dit Vehel +4
We introduce a shear experiment that quantitatively reproduces the main laws of seismicity. By continuously and slowly shearing a compressed monolayer of disks in a ring-like geome…
Hyper-Raman scattering from vitreous boron oxide: coherent enhancement of the boson peak
G. Simon, B. Hehlen, E. Courtens +2
Hyper-Raman scattering spectra of vitreous BO are reported and compared to Raman scattering results. The main features are indexed in terms of vibrations of structural unit…
The Inner Galaxy resolved at IJK using DENIS data
M. Unavane, Gerard Gilmore, N. Epchtein +3
We present the analysis of three colour optical/near-infrared images, in IJK, taken for the DENIS project. The region considered covers 17.4 square deg and lies within |l|<5 deg, |…
New neighbours: V. 35 DENIS late-M dwarfs between 10 and 30 parsecs
N. Phan-Bao, F. Crifo, X. Delfosse +7
This paper reports updated results on our systematic mining of the DENIS database for nearby very cool M-dwarfs (M6V-M8V, 2.0<I-J<3.0, photometric distance within 30 pc), We calibr…
New neighbours: IV. 30 DENIS late-M dwarfs between 15 and 30 parsecs
N. Phan-Bao, J. Guibert, F. Crifo +6
We present 30 new nearby (d<30 pc) red dwarf candidates, with estimated spectral types M6 to M8. 26 were directly selected from the DENIS database, and another 4 were first extract…
Interstellar extinction towards the inner Galactic Bulge
M. Schultheis, S. Ganesh, G. Simon +7
DENIS observations in the J (1.2 micron) and K_S (2.15 micron) bands together with isochrones calculated for the RGB and AGB phase are used to draw an extinction map of the inner G…
