Incomplete fusion versus breakup competition with weakly bound projectiles
F. A. Souza, M. G. Munhoz, J. Takahashi +8
The importance of the breakup channel in the vicinity of the Coulomb barrier (1<Ec.m./Vb<2) is investigated for the medium weight 6Li+59Co system. Three-body final-state analysis o…
The Intimate Link Between Accretion and BELR
F. Nicastro, A. Martocchia, G. Matt
In this paper I present evidence suggesting that the absence or presence of Hidden Broad Line Regions (HBLRs) in Seyfert 2 galaxies is regulated by the rate at which matter accrete…
The Role of Mass Asymmetry and Shell Structure in the Evaporation Residues Production
G. Fazio, G. Giardina, A. Lamberto +10
The effects of the entrance channel and shell structure of reacting nuclei on the experimental evaporation residues have been studied by analysing the 40Ar+176Hf, 86Kr+130,136Xe, 1…
Timing study of the isolated neutron star RX J0720.4-3125
Silvia Zane, Frank Haberl, Mark Cropper +4
We present a combined analysis of XMM-Newton, Chandra and Rosat observations of the isolated neutron star RX J0720.4-3125, spanning a total period of \sim 7 years. We develop a max…
Influence of Hipparcos on Hyades age estimates from three binary systems
E. Lastennet, D. Valls-Gabaud, T. Lejeune +1
Three independent sets of stellar theoretical models are tested with well-detached systems of the Hyades open cluster: 51 Tau, V818 Tau, and Tau. The choice of these objects…
Simultaneous (age, metallicity) estimates of the Hyades open cluster from three binary systems
E. Lastennet, D. Valls-Gabaud, T. Lejeune +1
Three binary systems in the Hyades open cluster, with known metallicity and good Johnson photometric data are used to test the validity of three independent sets of stellar evoluti…
