Star distribution around a massive black hole in a globular cluster
- J. Bahcall, R. Wolf
- Physics
- 1 October 1976
To predict the likely distribution of stars around a massive black hole in the core of a cluster of stars, an equation of the Fokker-Planck type is derived that describes the diffusion of stars in… Expand
Models for the Galaxy and the Predicted Star Counts
- J. Bahcall, R. M. Soneira
- Physics
- 1 September 1980
A detailed model is constructed for the disk and spheroid components of the Galaxy from which the distribution of visible stars and mass in the Galaxy is calculated. The application of star counts to… Expand
Solar Models: Current Epoch and Time Dependences, Neutrinos, and Helioseismological Properties
- J. Bahcall, M. Pinsonneault, S. Basu
- Physics
- 17 October 2000
We calculate accurate solar models and report the detailed time dependences of important solar quantities. We use helioseismology to constrain the luminosity evolution of the Sun and report the… Expand
Hubble Space Telescope Images of a Sample of Twenty Nearby Luminous Quasars
- J. Bahcall, S. Kirhakos, D. H. Saxe, D. Schneider
- Physics
- 20 November 1996
Observations with the Wide-Field Camera of the Hubble Space Telescope are presented for a representative sample of 20 intrinsically luminous quasars with redshifts smaller than 0.30. These… Expand
Star distribution around a massive black hole in a globular cluster. II. Unequal star masses
- J. Bahcall, R. Wolf
- Physics
- 15 September 1977
The steady-state distribution of stars around a massive black hole in a globular cluster is determined by solving numerically the coupled time-dependent Boltzmann equations for a system containing… Expand
HIGH ENERGY NEUTRINOS FROM COSMOLOGICAL GAMMA-RAY BURST FIREBALLS
- E. Waxman, J. Bahcall
- Physics
- 30 January 1997
Observations suggest that {gamma}-ray bursts (GRBs) are produced by the dissipation of the kinetic energy of a relativistic fireball. We show that a large fraction, {ge}10{percent}, of the fireball… Expand
Element Diffusion in the Solar Interior
- A. Thoul, J. Bahcall, A. Loeb
- Physics
- 6 April 1993
We study the diffusion of helium and other heavy elements in the solar interior by solving exactly the set of flow equations developed by Burgers for a multi-component fluid, including the residual… Expand
Solar models with helium and heavy-element diffusion
- J. Bahcall, M. Pinsonneault
- Physics
- 30 May 1995
Helium and heavy-element diffusion are both included in precise calculations of solar models. In addition, improvements in the input data for solar interior models are described for nuclear reaction… Expand
On the simultaneous analysis of several complete samples - The V/Vmax and Ve/Va variables, with applications to quasars
- Y. Avni, J. Bahcall
- Physics
- 1 February 1980
We derive methods for applying the V/V/sub max/ variable when several complete samples are analyzed simultaneously. A new, related, variable, V/sub e//V/sub a/, which is superior to V/V/sub max/ when… Expand
Helioseismological Implications of Recent Solar Abundance Determinations
- J. Bahcall, S. Basu, M. Pinsonneault, A. Serenelli
- Environmental Science, Physics
- 4 July 2004
We show that standard solar models are in good agreement with the helioseismologically determined sound speed and density as a function of solar radius, the depth of the convective zone, and the… Expand
