Abstract:
Galactic X-ray sources are diverse, ranging from active M dwarfs to
compact object binaries, and everything in between. The X-ray
landscape of today is rich, with point source catalogs such as those
from XMM-Newton, Chandra, and Swift, each with ≳105 sources and
growing. Furthermore, X-ray astronomy is on the verge of being
transformed through data releases from the all-sky SRG/eROSITA survey.
Many X-ray sources can be associated with an optical counterpart,
which in the era of Gaia, can be determined to be Galactic or
extragalactic through parallax and proper motion information. Here, I
present a simple diagram = the "X-ray Main Sequence", which
distinguishes between compact objects and active stars based on their
optical color and X-ray-to-optical flux ratio (FX/Fopt). As a proof of
concept, I present optical spectroscopy of six exotic accreting WDs
discovered using the X-ray Main Sequence as applied to the XMM-Newton
catalog. Looking ahead to surveys of the near future, I additionally
present SDSS-V optical spectroscopy of new systems discovered using
the X-ray Main Sequence as applied to the SRG/eROSITA eFEDS catalog.
