| Abstract: |
We have examined the UV and optical properties of twenty old-novae observed with IUE. The de-reddened continuum energy distribution of all stars is well described by a power-law distribution Fλ~λ−α with α ranging from 0.0 (GK Per) to 2.7 (V841 Oph). Our new values of EB−V have led to new estimates of the UV luminosities which range from less than 1 LSolar (DQ Her) to as much as 70 LSolar (HR Del and T Pyx). A tight correlation exists between LUV and MminV, and both these quantities show a definite correlation with the system inclination angle cos i, with the notable exceptions of the extra slow nova HR Del and of the recurrent nova T Pyx that are too bright. |
