Tiptopbase: the Iron Project and the Opacity Project Atomic Database
Abstract
The aims of the international collaborations, Opacity Project (OP), the IRON Project (IP), and the RmaX Network (The Opacity Project Team, Vol.1,2), IOPP, Bristol (1995,1996); Hummer et al., Astron. Astrophys. 279, 298 (1993) are to obtain accurate atomic data for radiative and collisional processes, and plasma opacities for astrophysical applications. A new, considerably enlarged, version of the existing electronic database TOPbase (http://heasarc.gsfc.nasa.gov OR http://vizier.u-strasbg.fr/OP.html) is under development. It is called TIPTOPBASE and will contain (i) photoionization cross sections (σ_PI), energy levels and oscillator strengths (f-values), and monochromatic and Rosseland mean opacities of atoms and ions with Z = 1 - 14, 16, 18, 20, 26, as well as new data for P, Cl, K, Ni II-III, (ii) collisional data for iron and iron peak elements, (iv) σ_PI at high energies including inner-shell ionization, (v) total and level specific unified recombination rate coefficients, (vi) f-values for inner-shell excitations in Fe VIII - XIII, (vi) relativistic fine structure σ_PI and f-values for selected ions, (vii) on-line computational facilities for 'customized' opacities and radiative forces for user-specified mixture of elements. Partial support from NASA is acknowledged.
