چکیده
Abstract We apply the jet-powered ILOT scenario to two recently studied intermediate luminosity optical transients (ILOTs), and find relevant shell mass jets’ energy that might account for outbursts of these ILOTs. In scenario, an accretion disk around one stars a binary system launches jets. The interaction jets with previously ejected slow converts kinetic thermal energy, part which is radiated away. models scenario. spherical model, accelerate shell, while in cocoon toy model penetrate into inflate hot bubbles, cocoons. consistent results.

Cosmic Explosions (optical Transients)
One of the principal motivations of wide-field and synoptic surveys is the search for and study of transients. By transients I mean those sources which arise from the background, are detected, and then fade away to oblivion. Transients in distant galaxies need to be sufficiently bright so as to be detectable and in almost all cases these transients are catastrophic events, marking the deaths of...
متن کاملOptical pulse shaping using optical coherent transients.
Using multiple temporally-overlapped, frequency offset and phase-tuned, linear frequency chirps, a new method of multi-GHz optical coherent transient optical pulse shaping and processing in inhomogeneously broadened rare-earth doped crystals is proposed. Using this technique with properly chirped laser sources, multi-GHz processing can be controlled with conventional low-bandwidth electronics a...
متن کاملExplaining the Gamma Ray Burst Lag/luminosity and Variability/luminosity Relations
Two different luminosity indicators have been recently proposed for Gamma Ray Bursts that use the lag between light curve peaks with hard and soft photons as well as the variability (’spikiness’) of the burst light curve. Schaefer, Deng, & Band have proven that both of these luminosity indicators are valid by finding a lag/variability relation for 112 BATSE bursts. Here, I provide simple and ge...
متن کاملReal-Time Detection of Optical Transients with RAPTOR
Fast variability of optical objects is an interesting though poorly explored subject in modern astronomy. Realtime data processing and identification of transient celestial events in the images is very important for such study as it allows rapid follow-up with more sensitive instruments. We discuss an approach which we have developed for the RAPTOR project, a pioneering closed-loop system combi...
متن کاملExploring jet-launching conditions for supergiant fast X-ray transients
Context. In the magneto-centrifugal mechanism for jet formation, accreting neutron stars are assumed to produce relativistic jets only if their surface magnetic field is weak enough (B ∼ 108 G). However, the most common manifestation of neutron stars are pulsars, whose magnetic field distribution peaks at B ∼ 10 G. If the neutron star magnetic field has at least this strength at birth, it must ...
