Abstract:
The X-ray source 1RXS J180431.1-273932 has been proposed as a new
member of the symbiotic X-ray binary (SyXB) class of systems, which
are composed of a late-type giant that loses matter to an extremely
compact object, most likely a neutron star. In this paper, we present
an optical campaign of imaging plus spectroscopy on selected candidate
counterparts of this object. We also reanalyzed the available archival
X-ray data collected with XMM-Newton.
