A Survey of Faint OB Stars in Carina
Graham J.A., Lynga G.
<Mem. Mt. Stromlo Obs. 18 (1965)>
=1965MmMtS..18.....G
================================================================================
ADC_Keywords: Stars, hot; MK spectral classification
Description:
A finding list is presented for OB stars in a 75 square degree
region centered on eta Carina. Completeness between 8.5 and 11.5 was
the goal. Crowding, rather than the plate limit determined the limiting
magnitude. The catalog contains HD, HDE, or CPD numbers,
positions, visual magnitudes, HDE types, and numbers in the Tonantzintla
Bulletins when available.
Introduction:
The spectral types were estimated from eight Uppsala Schmidt plates. The
magnitudes may be rough but were estimated against both photographic and
photoelectric sequences.
