Inferring information about rotation from stellar oscillations
M. J. Goupil, R. Samadi, J. Lochard +2
The first part of this paper aims at illustrating the intense scientific activity in the field of stellar rotation although, for sake of shortness, we cannot be exhaustive nor give…
Gamma-ray bursts from alternating-current jets
M. Sikora, M. C. Begelman, P. Coppi +1
We propose a gamma-ray burst scenario involving relativistic jets dominated by Poynting flux with alternating toroidal magnetic fields. Such a structure may arise naturally if the…
On application of multi-colour photometry of Scuti stars
J. Daszy{ń}ska-Daszkiewicz, W. A. Dziembowski, A. A. Pamyatnykh
In Scuti star models, the photometric amplitudes and phases exhibit a strong dependence on convection, which enters through the complex parameter, , which describes the bolo…
BeppoSAX and multiwavelength observations of BL Lacertae in 2000
M. Ravasio, G. Tagliaferri, G. Ghisellini +3
We present two BeppoSAX observations of BL Lac (2200+420) as part of a multiwavelength campaign performed in 2000. The source was in different states of activity: in June, the X-ra…
Constraints on stellar convection from multi-colour photometry of Delta Scuti stars
J. Daszynska-Daszkiewicz, W. A. Dziembowski, A. A. Pamyatnykh
In Delta Scuti star models, the calculated amplitude ratios and phase differences for multi-colour photometry exhibit a strong dependence on convection. These observables are tools…
Stability of matter in the accelerating spacetime
Miroslaw Kozlowski, Janina Marciak-Kozlowska
In the paper the Planck, Yukawa and Bohr forces were defined and calculated. It was shown that the Planck force mediates the universe acceleration. The Yukawa and Bohr forces descr…
