Constraints on blue straggler formation mechanisms in Galactic globular clusters from proper motion velocity distributions
N. W. C. Leigh, T. Panurach, M. Simunovic +10
For a sample of 38 Galactic globular clusters (GCs), we confront the observed distributions of blue straggler (BS) proper motions and masses (derived from isochrone fitting) from t…
Deep optical observations of G 65.3+5.7
Fotis Mavromatakis, Panayotis Boumis, John Papamastorakis +1
We present the first CCD mosaic of the supernova remnant G 65.3+5.7 in the optical emission lines of [O II] and [O III]. The new images reveal several diffuse and filamentary struc…
Neutron star envelopes and thermal radiation from the magnetic surface
J. Ventura, A. Y. Potekhin
The thermal structure of neutron star envelopes is discussed with emphasis on analytic results. Recent progress on the effect of chemical constitution and high magnetic fields on t…
The peculiar supernova remnant CTB 80
F. Mavromatakis, J. Ventura, E. V. Paleologou +1
Deep CCD exposures of the peculiar supernova remnant CTB 80 in the light of major optical lines have been obtained. These images reveal significant shock heated emission in the are…
The supernova remnants G67.7+1.8, G31.5-0.6 and G49.2-0.7
F. Mavromatakis, J. Papamastorakis, J. Ventura +3
Wide field CCD observations of three, less known, supernova remnants. Filamentary and diffuse emission is discovered from the supernova remnant G67.7+1.8. Emission can also be seen…
Ionization equilibrium and equation of state of hydrogen plasmas in strong magnetic fields
A. Y. Potekhin, G. Chabrier, Yu. A. Shibanov +1
We study hydrogen plasmas at magnetic fields B ~ 10^{12}-10^{13} Gauss, densities ~ 10^{-3}-10^3 g/cc and temperatures T ~ 10^{5.5}-10^{6.5} K, typical of photospheres of middle-ag…
