- W2098159498 abstract "Near - IR spectroscopic and photometric observations of the eruptive variables V838 Mon and V44.5 Puppis in the JHK bands are reported. These objects erupted in nova-like explosions but evolved into rather unique and enigmatic objects. One of unusual features of the V838 Mon spectra is the detection of several strong Ti1 lines in emission in the K band. These spectra also show the strong presence of the 12C0 bands. Deep water bands at 1.4 pm and 1.9 ,urn are also seen later in the object's evolution. Blackbody fits to the JHK photometric data show that V838 Mon evolves to low temperatures between 2400-2600 K after its outburst. The spectra of V445 Puppis are found to be hydrogen deficient and unusually rich in CI lines leading to the possibility that it is a rare Helium nova. The nature of both the objects is discussed and it is shown that they do not fit into known categories of eruptive variables." @default.
