The target: SBS 1150+599A
-
Detected in the Second Byurakan Sky Survey (SBS), classified
as stellar and a possible CV candidate in the halo. (V=17.5, l = 135.96,
b=55.94)
-
Garnavich & Stanek (1999) - obtained follow-up spectra
and determined the object was not a CV but
instead a young PN or symbiotic
star.
-
Tovmassian et al. (2001), obtained further spectra from a
number of sources and found a preliminary Oxygen abundance of less
than 500 times the solar value!
-
However, the spectra were not high-quality, and there were
no images taken. More study was called for.
Observations
-
Imaging: VATT and the WIYN
telescope took H-alpha + [NII] images of
SBS 1150+599A. Using tip-tilt, FWHM of the WIYN
images is 0.5"!
-
Spectroscopy: MMT and FLWO - MMT deeper, but has 2nd order
contam.
