Stark broadening parameter tables for Kr VIII [PDF]

open access: yesSerbian Astronomical Journal, 1999
Using a semiclassical approach, we have calculated electron−, proton−, and He III−impact line widths and shifts for 6 Kr VIII multiplets as a function of temperature and perturber density.

Use of the ESI-2007 scale to evaluate the 2003 Boumerdès earthquake (North Algeria)

open access: yesAnnals of Geophysics, 2016
In this study, we applied the environmental seismic intensity (ESI-2007) scale to a major recent Algerian earthquake. The ESI-2007 scale is an effective tool to assess the seismic hazard and has been applied to onshore earthquakes.

Stark broadening parameter tables for Na X [PDF]

open access: yesSerbian Astronomical Journal, 1998
Using a semiclassical approach, we have calculated electron−, proton−, and He III−impact line widths and shifts for 57 Na X multiplets as a function of temperature (200 000 K - 5 000 000 K) and perturber density (1017cm−3 - 1024cm−3.

Ringing effects reduction by improved deconvolution algorithm Application to A370 CFHT image of gravitational arcs [PDF]

open access: yes, 2003
We develop a self-consistent automatic procedure to restore informations from astronomical observations. It relies on both a new deconvolution algorithm called LBCA (Lower Bound Constraint Algorithm) and the use of the Wiener filter.

WR 110: A Single Wolf-Rayet Star With Corotating Interaction Regions In Its Wind? [PDF]

open access: yes, 2011
A 30-day contiguous photometric run with the MOST satellite on the WN5-6b star WR 110 (HD 165688) reveals a fundamental periodicity of P = 4.08 +/- 0.55 days along with a number of harmonics at periods P/n, with n ~ 2,3,4,5 and 6, and a few other ...

La physique nucléaire en astrophysique [PDF]

open access: yesAnnales de Physique, 2001
L'astrophysique nucleaire est sans nul doute l'une des branches les plus largement interdisciplinaires de la science et est intimement connectee a une tres grande variete d'autres domaines de recherche. Cet ouvrage se limite a une breve presentation des relations privilegiees qui se sont etablies entre l'astrophysique et la physique nucleaire.

Stark broadening parameter tables for Sc X, Sc XI, Ti XI and Ti XII [PDF]

open access: yesSerbian Astronomical Journal, 1998
By using the semiclassical-perturbation formalism, we have calculated electron-, proton-, and He III-impact line widths and shifts for 4 Sc X, 10 Sc XI, 4 Ti XI and 27 Ti XII multiplets, significant for investigation and modeling of different ...
