dc.description | We are grateful for the of data from the ESO Public Survey program ID 179.B-2002 taken with the VISTA telescope, data products from the Cambridge Astronomical Survey Unit, as well as data taken with the 6.5 m Magellan Telescopes located at Las Campanas Observatory, Chile. This research has made use of the AstroBetter blog and wiki, and was funded in part by the Fermi Guest Observer grant NNX14AQ36G (L. Chomiuk). We are also especially grateful for the useful discussions with J. Linford, K. Mukai, T. Nelson, M. Rupen, J. Sokoloski, and R. Williams. | en |
dc.description.abstract | It has recently been discovered that some, if not all, classical novae emit GeV gamma-rays during outburst. Despite using an unreliable method to determine its distance, previous work showed that nova V1324 Sco was the most gamma-ray luminous of all gamma-ray-detected novae. We present here a different, more robust, method to determine the reddening and distance to V1324 Sco using high-resolution optical spectroscopy. Using two independent methods, we derived a reddening of E(B-V)= 1.16+/- 0.12 and a distance limit of {r}<SUB>{{D</SUB>}}\gt 6.5 {kpc}. This distance is \gt 40% greater than the value used in the gamma-ray analysis, meaning that V1324 Sco has an even higher gamma-ray luminosity than previously calculated. We also use periodic modulations in the brightness, interpreted as the orbital period, in conjunction with pre-outburst photometric limits to show that a main-sequence companion is strongly favored. | en_US |
