The ultraviolet spectrum of the peculiar emission-line star GG Carinae

Using the transitions assigned here and previously by Camy-Peyret et al., it is possible to build up tables of energy levels for the excited states.. Such tables are important for

When the energy of the photoelectron is high enough t o excite an electron to the exciton states or to the continuum states, the photoelectron may be scattered t o

We have explored the constraints on the production and escape of ionizing photons in young galaxies by investigating the ultra- violet and optical emission-line properties of a

No emission components can be observed on HeI lines and some lines of neutral elements such as [CrI] are present so we can conclude that a cool dust shell is present (Table 1, Figs

The corresponding relative oscillator strength is put on a n abso- lute scale through the known absolute f-value of the selected reference line for which accurate
