Abstract:
This is the third installment of the Galactic O-Star Spectroscopic
Survey (GOSSS), a massive spectroscopic survey of Galactic O stars,
based on new homogeneous, high signal-to-noise ratio, R∼2500 digital
observations selected from the Galactic O-Star Catalog. In this paper,
we present 142 additional stellar systems with O stars from both
hemispheres, bringing the total of O-type systems published within the
project to 590. Among the new objects, there are 20 new O stars. We
also identify 11 new double-lined spectroscopic binaries, 6 of which
are of O+O type and 5 of O+B type, and an additional new tripled-lined
spectroscopic binary of O+O+B type. We also revise some of the
previous GOSSS classifications, present some egregious examples of
stars erroneously classified as O-type in the past, introduce the use
of luminosity class IV at spectral types O4-O5.5, and adapt the
classification scheme to the work of Arias et al.
Description:
Most of the spectra presented in Paper I (see III/274) were obtained
with the Albireo (Observatorio de Sierra Nevada-OSN-1.5m telescope)
and TWIN (Calar Alto-CAHA-3.5m telescope) spectrographs. On the other
hand, most of the spectra in Paper II (see III/274) were obtained with
the Boller & Chivens spectrograph at the Las Campanas (LCO) 2.5m du
Pont telescope. Starting with Paper II, some spectra were also
obtained with the ISIS spectrograph at the 4.2m William Herschel
Telescope (WHT) at the Observatorio del Roque de los Muchachos (ORM)
in La Palma, Spain. In this paper, we use data from all of the above
instruments and we also add a new one, OSIRIS, at the 10.4m Gran
Telescopio Canarias (GTC) at the ORM.
The GOSSS data in this paper were obtained between 2007 and 2015.
