Abstract:Symbiotic stars are interacting binaries with the longest orbital periods, and their multicomponent structure makes them rich astrophysical laboratories. The accretion of a high-mass-loss-rate red giant wind on to a white dwarf (WD) makes them promising Type Ia supernova (SN Ia) progenitors. Systematic surveys for new Galactic symbiotic stars are critical to identify new promising SN Ia progenitors (e.g. RS Oph) and to better estimate the total population size to compare against SN Ia rates. Central to the latter objective is building a complete census of symbiotic stars towards the Galactic bulge. Here we report on the results of a systematic survey of H{alpha} emission-line stars covering 35 deg^2^. It is distinguished

We have conducted a survey of H{alpha} emission-line stars towards the
Galactic bulge covering ~35 deg^2^. Deep optical spectroscopy and
I-band long-term light curves were presented for most of the sample,
revealing 20 new and 15 possible symbiotic stars, as well as several
other unusual emission-line stars.
