FBS 0107-082: A Symbiotic Binary in a Rare Prolonged Outburst?
R.K. Honeycutt, S. Kafka
TL;DR
FBS 0107-082 is identified as a symbiotic nova undergoing a rare prolonged outburst, characterized by strong emission lines, nebular spectrum, and minimal variability, based on new optical spectroscopy and multi-wavelength data.
Contribution
This study reclassifies FBS 0107-082 as a symbiotic nova in prolonged outburst using comprehensive spectroscopic and photometric analysis.
Findings
Strong hydrogen Balmer lines and nebular forbidden lines observed.
Absorption features indicate an early-F photosphere.
Minimal variability over various time scales.
Abstract
FBS0107-082 is an emission line object previously classified as a nova-like cataclysmic variable star. New optical spectroscopy shows very strong hydrogen Balmer lines, along with a nebular forbidden line spectrum and absorption features from an early-F photosphere. When combined with other IR and optical data from the literature, these data point to the object being a symbiotic nova seen in a prolonged outburst. Photometry on time scales of minutes, days, and years show only very weak variability.
