There is strong anticipation that the Leonid meteor shower could produce storm-level activity in 1998 and/or 1999. The well-documented Leonid outburst in 1996...
The Li I resonance line in the spectra of X-ray nova accretion discs
We study the formation of the Li I lambda 6708 Angstroms resonance doublet in spectra of X-ray novae during the stage of outburst decay. We discuss the general...
The Liège Oscillation code can be used as a stand-alone program or as a library of subroutines that the user calls from a Fortran main program of his own to...
The limit of mass for gravitational collapse and nuclear forces at short distance
On the basis of the current knowledge about the size of the neutron, the nucleon-nucleon interaction, and the limit on the ratio Gm/c2R < 4/9 imposed by General...
The Limited Influence of Pressure Gradients on Late-Type Stellar Line Asymmetries
Line asymmetries and shifts are powerful tools for studying velocity fields in the stellar photospheres. Other effects, however, could also generate asymmetries...
The Line Emission Region in III Zw 2: Kinematics and Variability
We have studied the Lyα, Hβ, Hα, and Mg II λ2798 line profiles of the Seyfert 1 galaxy III Zw 2. The shapes of these broad emission lines show evidence of a...
The Line-of-Sight Velocity Distributions of Intracluster Planetary Nebulae in the Virgo Cluster Core
Radial velocities of 40 intracluster planetary nebulae (ICPNs) in the Virgo Cluster were obtained with the new multifiber FLAMES spectrograph on UT2 at the Very...
The link between the star formation history and [α/Fe ]
The abundance ratios between key elements such as iron and α-process elements carry a wealth of information on the star formation history (SFH) of galaxies. So...
The lithium abundance in the extremely metal-deficient dwarf G 64-12
The authors have measured the 7Li abundance in G 64-12 an extremely metal-deficient dwarf [Fe/H] = -3.5 (Carney and Peterson, 1981) with effective temperature...
