Monitoring and Study of V2672 Oph
Abstract:
V2672 Oph (Nova Oph 2009) was discovered by Koichi Itagaki in outburst on August 16, 2009. It peaked at about magnitude 12, and rapidly faded. Low- and medium-resolution spectroscopy showed broad, prominent H_alpha emission with FWHM 11500 km/s on top of a featureless, but very red, continuum.
Justification:
The rapid fading indicates a very bright nova, placed at a great distance essentially on the opposite side of the galaxy from the Sun. Its similarities to the recurrent nova U Sco, which is a progenitor for type Ia supernovae, makes it a critical target for ongoing study. The recurrent nova classification, if confirmed, gives V2672 Oph high scientific value, especially in archival research, photometric recalibration, and future monitoring for potential outbursts.
