Abstract
In this paper we present an atlas of near-infrared spectrophotometry of symbiotic novae and report results from nearly contemporaneous IUE observations. The data cover RT Ser, AG Peg, V1016 Cyg, V1329 Cyg, HM Sge, and Pu Vul, most of the known symbiotic novae that are observable from the northern hemisphere. Emission-line strengths for both spectral regions are tabulated. Extinction values are derived from He II λ1640 in the UV and He II λ10124 in the infrared. Spectral types are determined for the cool giant component using infrared absorption features. The extinction and apparent J (1.25 μm) magnitude measured from the spectrophotometry are combined with the known relation between spectral type and absolute magnitude to derive distances for each system.
