Supermassive Stars in Quasar Disks

  title={Supermassive Stars in Quasar Disks},
  author={Jeremy Goodman and Jonathan C. Tan},
  journal={The Astrophysical Journal},
We propose that supermassive stars may form in quasar accretion disks, and we discuss possible observational consequences. The structure and stability of very massive stars are reviewed. Because of high accretion rates, quasar disks are massive, and the fringes of their optically luminous parts are prone to fragmentation. Starting from a few hundred solar masses, a dominant fragment will grow to the isolation mass, which is a significant fraction of the disk mass, more quickly than the fragment… Expand

Massive stars in subparsec rings around galactic centres
It is found that protostars accrete gaseous disc matter at prodigious rates, and this result explains observations of rings of young massive stars in the authors' Galaxy and in M31, and it is predicted that more such rings will be discovered. Expand
Star formation in accretion discs and SMBH growth
Accretion disks around active galactic nuclei are potentially unstable to star formation at large radii. We note that when the compact objects formed from some of these stars spiral into the centralExpand
Fragmentation of massive protostellar discs
We examine whether massive-star accretion discs are likely to fragment due to self-gravity. Rapid accretion and high angular momentum push these discs toward fragmentation, whereas viscous heatingExpand
Protostellar Disks: Formation, Fragmentation, and the Brown Dwarf Desert
We argue that gravitational instability of typical protostellar disks is not a viable mechanism for the fragmentation into multiple systems (binary stars, brown dwarf companions, or gas giantExpand
Star Captures by Quasar Accretion Disks: A Possible Explanation of the M-σ Relation
A new theory of quasars is presented in which the matter of thin accretion disks around black holes is supplied by stars that plunge through the disk. Stars in the central part of the host galaxy areExpand
Cooling of Young Stars Growing by Disk Accretion
In the initial formation stages young stars must acquire a significant fraction of their mass by accretion from a circumstellar disk that forms in the center of a collapsing protostellar cloud.Expand
Star-forming accretion flows and the low-luminosity nuclei of giant elliptical galaxies
The luminosities of the centres of nearby elliptical galaxies are very low compared to models of thin disc accretion on to their black holes at the Bondi rate, typically a few hundredths to a fewExpand
Star Formation in Quasar Disk
Using a version of the ZEUS code, we carry out two-dimensional simulations of self-gravitating shearing sheets, with application to QSO accretion disks at a few thousand Schwarzschild radii,Expand
Starbursts near supermassive black holes: young stars in the Galactic Centre, and gravitational waves in LISA band
We propose a scenario in which massive stars form in a self-gravitating gaseous disc around a supermassive black hole (SMBH). We analyse the dynamics of a disc forming around an SMBH, in which theExpand
Supermassive star formation via episodic accretion: protostellar disc instability and radiative feedback efficiency
The formation of SMSs is a potential pathway to seed SMBHs in the early universe. A critical issue for forming SMSs is stellar UV feedback, which may limit the stellar mass growth via accretion. InExpand


Star Formation in Accretion Disks Around Massive Black Holes and Pregalactic Enrichment
Broad Absorption Lines (BALs) prove the existence of a high velocity outflowing gas with metallicities larger than solar in the central few parsecs of high redshift quasars. At the same distance fromExpand
Star formation and evolution in accretion disks around massive black holes
We develop a model for the outer gravitationally unstable regions of accretion disks around massive black holes, for primeval or solar abundances. First we study star formation and evolution in aExpand
Selfgravity and QSO disks
It is well known that the outer parts of QSO accretion disks are prone to selfgravity if heated solely by orbital dissipation. Such disks might be expected to form stars rather than accrete onto theExpand
Self-gravitating accretion disks in active galactic nuclei
Accretion onto supermassive black holes (SBHs) is widely believed to be responsible for the phenomena of active galactic nuclei (AGN). While there has been considerable theoretical work on the innerExpand
Red Giant--Disk Encounters: Food for Quasars?
We explore the role that red giants might play in the central regions of Active Galactic Nuclei. Due to their large radii and the low binding energy of the stellar envelope, giants are vulnerable toExpand
Star trapping and metallicity enrichment in quasars and active galactic nuclei
Recent observational evidence suggests that the metallicity in quasars within a wide range of redshifts, in particular in gas flowing out of the nuclear regions, may be approximatelyExpand
Evolution of self-gravitating accretion disks in active galactic nuclei
The evolution of self-gravitating gaseous disks in active galactic nuclei on scales of about 10-1000 pc is investigated. Star formation is a plausible outcome of the Jeans instability operating in aExpand
Self-gravity and quasi-stellar object discs
The outer parts of standard steady-state accretion discs around quasi-stellar objects (QSOs) are prone to self-gravity, and they might be expected to fragment into stars rather than feed the centralExpand
The Formation of Massive Stars from Turbulent Cores
Observations indicate that massive stars in the Galaxy form in regions of very high surface density, � � 1 gc m � 2 . Clusters containing massive stars and globular clusters have a column densityExpand
Timescales for planetary accretion and the structure of the protoplanetary disk
Abstract This paper outlines a unified scenario for Solar System formation consistent with astrophysical constraints. Jupiter's core could have grown by runaway accretion of planetesimals to a massExpand
