چکیده
We present simulated optical light curves of super-Eddington tidal disruption events (TDEs) using the zero-Bernoulli accretion (ZEBRA) flow model, which proposes that during phase, disc is quasi-spherical, radiation-pressure dominated, and accompanied by production strong jets. construct for both on- off-axis (with respect to jet) observers account anisotropic nature jetted emission. find at wavelengths, emission from orders magnitude brighter than produced jet, even with boosting synchrotron self-Compton. Comparing observed TDE Swift J2058.4+0516, we ZEBRA model accurately captures timescale remains reproduces luminosity transient. However, shape deviate early times radius temperature our modelled are $\sim2.7 - 4.1$ smaller $\sim1.4 2.3$ larger, respectively, observed. suggest this indicates inflates more, more rapidly, currently predicted discuss possible extensions this. Such refinements, coupled valuable new data upcoming large scale surveys, could help resolve TDEs how they powered.

Revisiting Optical Tidal Disruption Events with iPTF16axa
We report the discovery by the intermediate Palomar Transient Factory (iPTF) of a candidate tidal disruption event (TDE) iPTF16axa at z = 0.108, and present its broadband photometric and spectroscopic evolution from 3 months of follow-up observations with ground-based telescopes and Swift. The light curve is well fitted with a t decay, and we constrain the rise-time to peak to be <49 rest-frame...
متن کاملSpectral energy distribution of super - Eddington flows
Spectral properties of super-Eddington accretion flows are investigated by means of a parallel line-of-sight calculation. The subjacent model, taken from two-dimensional radiation hydrodynamic simulations by Ohsuga et al. (2005), consists of a disc accretion region and an extended atmosphere with high velocity outflows. The non-gray radiative transfer equation is solved, including relativistic ...
متن کاملTidal disruption Eddington envelopes around massive black holes
Optically-thick envelopes may form following the tidal disruption of a star by a massive black hole. Such envelopes would reprocess hard radiation from accretion close to the black hole into the UV and optical bands producing AGN-luminosity flares with duration ∼ 1 year. We show that due to relativistic effects, the envelopes are convective. If convection is efficient, then the structure of the...
متن کاملOptical Flares from the Tidal Disruption of Stars by Massive Black Holes
A star that wanders too close to a massive black hole (BH) is shredded by the BH’s tidal gravity. Stellar gas falls back to the BH at a rate initially exceeding the Eddington rate, releasing a flare of energy. In anticipation of upcoming transient surveys, we predict the light curves and spectra of tidal flares as a function of time, highlighting the unique signatures of tidal flares at optical...
متن کاملINEXTENSIBLE FLOWS OF CURVES IN LIE GROUPS
In this paper, we study inextensible ows in three dimensional Lie groups with a bi-invariant metric. The necessary and sucient conditions for inextensible curve ow are expressed as a partial dierential equation involving the curvatures. Also, we give some results for special cases of Lie groups.
