Abstract:
We study the optical spectral properties of a sample of stars showing
far infrared colours similar to those of well-known planetary nebulae.
The large majority of them were unidentified sources or poorly known
in the literature at the time when this spectroscopic survey started,
some 15 years ago.
We present low-resolution optical spectroscopy, finding charts and
improved astrometric coordinates of a sample of 253 IRAS sources.
Description:
The spectroscopic observations were conducted during several runs
spanning 15 years from March 1988 to June 2003. The observations from
the Southern Hemisphere were carried out in most cases at the European
Southern Observatory (ESO, La Silla, Chile) with the 1.5m ESO
telescope, equipped with a Boller & Chivens spectrograph. The first
and last runs of observations were carried out at the 3.6m ESO
telescope, located at the same site, using the ESO Faint Object
Spectrograph and Camera EFOSC1 in the first run and EFOSC2 in the last
one. The observations from the Northern Hemisphere were carried out at
the 2.5m Isaac Newton Telescope at the Observatorio del Roque de los
Muchachos (La Palma, Spain), using the IDS spectrograph, and at the
2.2m telescope at the Observatorio Hispano-Aleman (Calar Alto,
Spain), also equipped with a Boller & Chivens spectrograph.
