Abstract:
Two regions in the Large Magellanic Cloud, centered at 05:11-66:08
(34B) and 05:27-72:15 (47B) have been searched for OB and supergiant
stars. A catalogue of 312 stars is presented in which objective prism
spectral types, positions (1975), approximate B magnitudes and
cross-identifications are given.
Description:
An objective-prism survey of the LMC was made with the Lichigan Curtis
Schmidt Telescope at the Cerro Tololo Inter-American Observatory. The
prims gives a dispersion of 136nm/mm at Hγ and covers the
spectral range 330-540nm when used with nitrogen baked, IIIa-J plates.
The 60-min exposuers reach stars of apparent magnitude ∼16.
Accurate positions and more reliable photometry of the stars were added
in July 2017, using the finding charts of the authors, and the Aladin
tool (Bonnarel et al. 2000A&AS..143...33B 2000A&AS..143...33B)
In addition, accurate positions of the B stars in Field 39 as given
by Shobbrook and Visvanathan (1987MNRAS.225..947S 1987MNRAS.225..947S, Table A1) are
presented in the file "pl39.dat".
