نویسنده
چکیده
Within the standard internal shock scenario, synchrotron emission would produce a spectrum with slope Fν ∝ ν −1/2, as immediate consequence of the cooling timescale being shorter than the integration time. This is in disagreement with the harder observed spectra, indicating that a different mechanism is responsible for the burst emission. Furthermore in this scenario pair production is expected when photons produced by inverse Compton emission are taken into account.

The possible low-frequency radio emission from the progenitors of gamma ray bursts can experience a delay from tens of seconds to hours on the way to the observer due to the dispersion in galactic and extragalactic plasma, and thus reach the observer as a radio afterglow of the burst. This opens a unique possibility (peculiar ”Time Machine”) of seeing what happened in that place before the cata...

I review the observational properties of SW Sex stars. I show that they can be explained by an accretion stream overflowing the disc, combined with an accretion disc wind. I suggest that SW Sex behaviour is caused by episodes of very high mass transfer, which are balanced by VY Scl low states.
