Outflows are frequently studied in the near-infrared (NIR) since the H2 emission in this wavelength range often traces the shocked molecular gas. However, the mechanisms behind the H2 emission detected in IRAS 19410+2336 have not been clarified yet. We present here spatially resolved NIR spectroscopy which allows us to verify whether the H2 emission originates from thermal emission in shock fronts or from fluorescence excitation by non-ionizing UV photons. Moreover, NIR spectroscopy also offers the possibility of studying the characteristics of the putative driving source(s) of the H2 emission by the detection of photospheric and circumstellar spectral features, and of the environmental conditions (e.g. extinction). We obtained long-slit, intermediate-resolution, NIR spectra of IRAS 19410+2336 using LIRIS, the NIR imager/spectrographer mounted on the 4.2m William Herschel Telescope. As a complement, we also obtained J, H and Ks images with the Las Campanas 2.5m Du Pont Telescope, and archival mid-infrared (MIR) Spitzer-images at 3.6, 4.5, 5.8 and 8.0um. Description: J, H and Ks images were taken with the Las Campanas 2.5m Du Pont Telescope on 1996 May 26. File Summary:
