Scientific paper
We present the results of a near-IR photometric and spectroscopic monitoring campaign to further investigate the outburst of the young, pre-main sequence star, SSV13. Our dataset covers a 3 years time period and starts at the time when SSV13 first became optical visible. We find that over our monitoring period, SSV13 has remained close to its post-outburst brightness. Some brightness fluctuation, however, detected. These have a typical (max-to-min) timescale of ~500 days with brightness modulations of ~0.5mag. During these variations, no significant changes in near-IR colour are observed. The spectroscopic emission features seen in SSV13 remained constant in strength over the same period. We discuss our data in relation to earlier observations and suggest that our data lend further support for the SSV13 being an EXor rather than FUor.
