Abstract:
The IPHAS Hα survey provides a rich database to search for
emission-line sources in the northern Galactic plane.
We are systematically searching for symbiotic stars in the Milky Way
using IPHAS. Our final goal, a complete census of this class of
objects in the Galaxy, is a fundamental figure for discussing their
overall properties and relevance to other classes of stars.
Candidate symbiotic stars were selected using a refined combination of
IPHAS and 2MASS photometric colours. Optical spectroscopy, together
with the analysis of their spectral energy distribution in the IR,
were obtained to confirm their nature and determine their main
properties.
Description:
We obtained spectra for 18 candidate symbiotic stars in May, June, and
December 2012 at the 10.4m Gran Telescopio Canarias (GTC) at the
Observatorio del Roque de los Muchachos (La Palma, Spain). The OSIRIS
instrument was used in its long-slit mode. The combination of grism
R1000B and a slit width of 1" provides a spectral dispersion of
2.1Å per (binned x2) pixel, a resolution of 7Å, and a spectral
coverage from 3650 to 7850Å. Exposure times ranged between 100s and
800s, depending of the magnitude of each object.
