Evidence of Deterministic Components in the Apparent Randomness of GRBs: Clues of a Chaotic Dynamic
G. Greco, R. Rosa, G. Beskin +5
Prompt γ-ray emissions from gamma-ray bursts (GRBs) exhibit a vast range of extremely complex temporal structures with a typical variability time-scale significantly short - as fas…
FAVOR (FAst Variability Optical Registration) -- A Two-telescope Complex for Detection and Investigation of Short Optical Transients
G. Beskin, V. Bad'in, A. Biryukov +25
An astronomical complex intended to detect optical transients (OTs) in a wide field and follow them up with high time resolution investigation is described.
The X-ray transient XTE J1859+226 in Outburst & Quiescence
C. Zurita, C. Sanchez-Fernandez, J. Casares +11
We present optical photometry and spectroscopy of the X-ray transient XTE J1859+226, obtained during outburst and its subsequent decay to quiescence. Both the X-ray and optical pro…
The optical light curve of GRB 970228 refined
N. Masetti, C. Bartolini, A. Guarnieri +1
We present the R and V light curves of the optical counterpart of GRB 970228. A critical analysis of all the available data is made in light of the results achieved in the recent G…
Did GRB 970228 and GRB 970508 present similar optical properties?
C. Bartolini, G. M. Beskin, A. Guarnieri +2
The analysis of the light curves of the optical counterparts of GRB 970228 and GRB 970508 points out remarkable similarities. The spectral distribution obtained from the color indi…
