Abstract (from CDS):

We present low-resolution spectra collected with the Spectral Energy Distribution Machine (SEDM) for an IW And-type dwarf nova, HO Puppis, and a Be star, V722 Tauri. The SEDM is an integrated field unit spectrograph mounted on the 60 inch telescope at the Palomar Observatory, with a spectral resolution of R ∼ 100 in the optical wavelength range. The Hα emission line was clearly detected for the bright Be star V722 Tauri at ∼12.5 mag, but barely detected in the spectra for the ∼13.7 mag HO Puppis. Our SEDM observations could be used as guidance for observing similar objects with the SEDM, as well as other R ∼ 100 spectrographs, in the future.
