Abstract:
We present a new census of Galactic and extragalactic symbiotic stars
(SySts). This compilation contains 323 known and 87 candidate SySts.
Of the confirmed SySts, 257 are Galactic and 66 extragalactic. The
spectral energy distributions (SEDs) of 348 sources have been
constructed using 2MASS and AllWISE data. Regarding the Galactic
SySts, 74% are S types, 13% D, and 3.5% D'. S types show an SED peak
between 0.8 and 1.7µm, whereas D types show a peak at longer
wavelengths between 2 and 4µm. D' types, on the other hand, display
a nearly flat profile. Gaia distances and effective temperatures are
also presented. According to their Gaia distances, S types are found
to be members of both thin and thick Galactic disk populations, while
S+IR and D types are mainly thin disk sources. Gaia temperatures show
a reasonable agreement with the temperatures derived from SEDs within
their uncertainties. A new census of the OVIλ6830
Raman-scattered line in SySts is also presented. From a sample of 298
SySts with available optical spectra, 55% are found to emit the line.
No significant preference is found among the different types. The
report of the OVIλ6830 Raman-scattered line in non-SySts is
also discussed as well as the correlation between the Raman-scattered
OVI line and X-ray emission. We conclude that the presence of the OVI
Raman-scattered line still provides a strong criterion for identifying
a source as a SySt.

Note (3): Symbiotic stars (SySts) are classified into two main categories based
on their near-infrared data (Allen & Glass 1974MNRAS.167..337A 1974MNRAS.167..337A ;
Webster & Allen 1975MNRAS.171..171W 1975MNRAS.171..171W):
(i) those with a near-IR color temperature of ∼3000-4000K, which is
attributed to the temperature of a K, M, or G spectral-type giant
(stellar or S-type SySts), and
(ii) those with a near-IR color temperature around 700-1000K,
indicating a warm dusty circumstellar envelope surrounding a more
evolved AGB star, usually a Mira variable (dusty or D-type SySts).
Allen (1982ASSL...95...27A 1982ASSL...95...27A) added a third type of SySt, namely the D'
type, in order to separate those with SED profiles that peak at even
longer wavelengths than the normal D type between 20 and 30um. The SED
profiles of the S+IR type are well spread out along the wavelength
range between 0.9 and 1.7um (Figure 5).
Note (4): Corrected for the blackbody approximation (see Section 3.1).
Note (5): Code as follows:
X = OVI line not detected
C = OVI line detected
C? = uncertain detection
