Historical light curve and the 2016 outburst of the symbiotic star StHalpha 169.

MUNARI U., GRAZIANI M. and JURDANA-SEPIC R.

Abstract (from CDS):

Accurate BVRI optical photometry of StHa 169 has been collected during the period 2005-2016. It reveals two outbursts, in 2009 and 2016, both peaking at B=13.6. The mean brightness in quiescence was B=15.29. In response to the 2016 outburst, the integrated absolute flux of the emission lines increased by a factor of 7 for Balmer, 9 for HeI lines, and 4.5 for HeII 4686, the Balmer continuum turned into strong emission, and [NeV] 3526 and OVI Raman 6825 Ang emissions disappeared. We have reconstructed the 1897-1951 B-band light curve of StHa 169 from Harvard historical plates. On top of a slow decline from a large outburst, ending in 1916, several brightenings are visible. Two fast-evolving outbursts, separated by 510 days, occurred in 1934 and 1935, peaking at B=13.7. The brightness in quiescence was the same as we measured in 2005-2016.
