Wind-reprocessed transients from stellar-mass black hole Tidal Disruption Events

چکیده

ABSTRACT Tidal disruptions of stars by stellar-mass black holes are expected to occur frequently in dense star clusters. Building upon previous studies that performed hydrodynamic simulations these encounters, we explore the formation and long-term evolution thick, super-Eddington accretion disks formed. We build a disk model includes fallback material from tidal disruption, onto hole, mass losses through winds launched association with flow. demonstrate bright transients when radiation central engine powered hole is reprocessed at large radii optically-thick wind. By combining disruption events our + wind model, compute light curves wind-reprocessed for wide range stellar masses encounter penetration depths. find typical peak bolometric luminosities roughly $10^{41}\!-\!10^{44}\,$erg s−1 (depending mostly on physics parameters) temperatures $10^5\!-\!10^6\,$K, suggesting emission ultraviolet/blue bands. predict all-sky surveys such as Vera Rubin Observatory ULTRASAT will detect up thousands per year clusters out distances several Gpc.

Enhanced Tidal Disruption Rates from Massive Black Hole Binaries

“Hard” massive black hole (MBH) binaries embedded in steep stellar cusps can shrink via threebody slingshot interactions. We show that this process will inevitably be accompanied by a burst of stellar tidal disruptions, at a rate that can be several orders of magnitude larger than that appropriate for a single MBH. Our numerical scattering experiments reveal that: 1) a significant fraction of s...

Tidal Disruption of Stellar Objects by Hard Supermassive Black Hole Binaries

Supermassive black hole binaries (SMBHBs) are expected by the hierarchical galaxy formation model in ΛCDM cosmology. There is some evidence in the literature for SMBHBs in AGNs, but there are few observational constraints on the evolution of SMBHBs in inactive galaxies and gas-poor mergers. On the theoretical front, it is unclear how long is needed for a SMBHB in a typical galaxy to coalesce. I...

Stellar disruption events support the existence of the black hole event horizon

Many black hole (BH) candidates have been discovered in X-ray binaries and in the nuclei of galaxies. The prediction of Einstein’s general relativity is that BHs have an event horizon – a one-way membrane through which particles fall into the BH but cannot exit. However, except for the very few nearby supermassive BH candidates, our telescopes are unable to resolve and provide a direct proof of...

A Tidal Disruption Event in a Nearby Galaxy Hosting an Intermediate Mass Black Hole

We report the serendipitous discovery of a bright point source flare in the Abell cluster A1795 with archival EUVE and Chandra observations. Assuming the EUVE emission is associated with the Chandra source, the X-ray 0.5–7 keV flux declined by a factor of ∼2300 over a time span of 6 yr, following a power-law decay with index ∼2.44 ± 0.40. The Chandra data alone vary by a factor of ∼20. The spec...

Mass loss from a magnetically driven wind emitted by a disk orbiting a stellar mass black hole

The source of cosmic gamma–ray bursts (hereafter GRBs) is usually believed to be a stellar mass black hole accreting material from a thick disk. The mechanism for the production of a relativistic wind by such a system is still unknown. We investigate here one proposal where the disk energy is extracted by a magnetic field amplified to very large values B ∼ 10 G. Using some very simple assumptio...
