Title: Synopic Spectroscopy of Bright Novae: A Feasibility Study

Abstract: The ability to monitor galactic novae at high cadence is revealing new puzzles about just how white dwarf stars explode and lose mass. High cadence absorption line spectroscopy shows that the mass loss in many novae is highly complex. We can resolve the origin of absorption systems; correlations with OIR photometry are revealing insights into the process. We request a total of 2 nights with LCO/NRES to a.) obtain a cross-calibration with our high dispersion {it Chiron} spectra, and b.) obtain a high-cadence sequence of synoptic spectra of the next bright galactic nova.

Program Type: Standard/LCO

Scheduled Nights:
Run 1 (2017B):  LCO-1m/NRES -- 29hrs
