Broad-line region size and black hole mass in high-z AGN
Ismael Botti, Paulina Lira, Hagai Netzer +3
In this contribution we briefly review the reverberation mapping technique and its results for low and intermidiate luminosity AGNs. Then we present a monitoring campaign of high-l…
The Realm of the First Quasars in the Universe: the X-ray View
C. Vignali, W. N. Brandt, O. Shemmer +3
We review the X-ray studies of the highest redshift quasars, focusing on the results obtained with Chandra and XMM-Newton. Overall, the X-ray and broad-band properties of z>4 quasa…
Silicates in D-type symbiotic stars: an ISO overview
R. Angeloni, M. Contini, S. Ciroi +1
We investigate the IR spectral features of a sample of D-type symbiotic stars. Analyzing unexploited ISO-SWS data, deriving the basic observational parameters of dust bands and com…
On the effects of the stellar magnetic field on the structure of T Tauri accretion discs
Y. Ulchin, O. Regev, G. A. Wynn
The structure of accretion discs around magnetic T Tauri stars is numerically calculated using a particle hydrodynamical code, in which magnetic interaction is included in the fram…
Formation of the Planetary Sequence in a Highly Flattened Disk of Frequently Colliding Planetesimals
Evgeny Griv, Michael Gedalin, Edward Liverts +2
The kinetic theory is used to study the evolution of the self-gravitating disk of planetesimals. The effects of frequent collisions between planetesimals are taken into account by…
Weakly nonlinear theory of the Jeans instability in disk galaxies of stars
Evgeny Griv, Michael Gedalin, David Eichler +1
The reaction of collective oscillations excited in the interaction between aperiodically growing Jeans-type gravity perturbations and stars of a rapidly rotating disk of flat galax…
