A radio jet from the optical and x-ray bright stellar tidal disruption flare ASASSN-14li.
The tidal disruption of a star by a supermassive black hole leads to a short-lived thermal flare. Despite extensive searches, radio follow-up observations of known thermal stellar tidal disruption flares (TDFs) have not yet produced a conclusive detection. We present a detection of variable radio emission from a thermal TDF, which we interpret as originating from a newly launched jet. The multi...
متن کاملSRG/eROSITA prospects for the detection of stellar tidal disruption flares
We discuss the potential of the eROSITA telescope on board the Spectrum-RoentgenGamma (SRG) observatory to detect stellar tidal disruption events (TDE) during its 4-year all-sky survey. We propose to distinguish such events from other X-ray transients using two criteria: i) large (more than a factor of 10) X-ray variation between two subsequent 6-month scans of the sky and ii) soft X-ray spectr...
متن کاملA New Way to Detect Massive Black Holes in Galaxies: the Stellar Remnants of Tidal Disruption
We point out that the tidal disruption of a giant may leave a luminous (10−10 erg/s), hot (10−100 eV) stellar core. The “supersoft” source (SSS) detected by Chandra at the center of M31 may be such a core; whether or not it is, the observations have shown that such a core is detectable, even in the center of a galaxy. We therefore explore the range of expected observational signatures, and how ...
متن کاملTidal 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...
متن کاملStellar Tidal Processes Near Massive Black Holes
Close tidal interactions of stars with a central massive black hole (MBH) or with other stars in the high density cusp around it can affect a significant fraction of the stellar population within the MBH radius of influence. We consider three strong processes that have the potential of modifying stellar structure and evolution there. (1) Tidal spin-up by hyperbolic star-star encounters. (2) Tid...
