On the completeness of the analysis of third and fourth spectra of the iron group, and the spectra of early B stars
(Elsevier, 1988-04-02)
The spectroscopic analysis of normal, early B stars requires a sound atomic data base, especially for the third and fourth spectra of the iron-group elements. We review the present status of the term analyses of third and ...
Protostellar Disk Formation and Early Evolution
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-03)
This contribution describes the formation of circumstellar disks and their earliest evolutionary phases when self-gravity in the disk plays a crucial role in eliciting the transport of mass and angular momentum. We first ...
A large air shower array to search for astrophysical sources emitting [gamma]-rays with energies >=1014 eV
(Elsevier, 1994-07-15)
We describe the technical details and the performance of a large array which detects both the electron and muon components in extensive air showers with energies >= 1014 eV. The array was designed to search for [gamma]-rays ...
