We search for LBV stars in galaxies outside the Local Group. Here we present a study of two bright $H\alpha$ sources in the NGC 247 galaxy. Object j004703.27-204708.4 ($M_V=-9.08 \pm 0.15^m$) shows the spectral lines typical for well-studied LBV stars: broad and bright emission lines of hydrogen and helium He I with P Cyg profiles, emission lines of iron Fe II, silicon Si II, nitrogen N II and carbon C II, forbidden iron [Fe II] and nitrogen [N II] lines. The variability of the object is… Expand

New luminous blue variable candidates in NGC 4736
We have found three new LBV candidates in the star-forming galaxy NGC 4736. They show typical well-known LBV spectra, broad and strong hydrogen lines, He I lines, many Fe II lines, and forbidden [FeExpand
Luminous and Variable Stars in NGC 2403 and M81
We present the results of spectroscopy and multi-wavelength photometry of luminous and variable star candidates in the nearby spiral galaxies NGC 2403 and M81. We discuss specific classes of stars,Expand
A New Luminous Blue Variable in the Giant Extragalactic H II Region NGC 2363
We report the discovery of an erupting luminous blue variable (LBV) star in the giant H II region NGC 2363, the most massive star-forming region in the Magellanic irregular galaxy NGC 2366. This LBV,Expand
On the population of galactic Luminous Blue Variables
We report the first results of a long term infrared monitoring campaign of known and candidate galactic Luminous Blue Variables (LBVs). In particular, we are able to confirm the LBV nature ofExpand
Discovery of a new bona fide luminous blue variable in Norma
We report the results of optical spectroscopy of the candidate evolved massive star MN44 revealed via detection of a circular shell with the Spitzer Space Telescope. First spectra taken in 2009Expand
Luminous and Variable Stars in M31 and M33. II. Luminous Blue Variables, Candidate LBVs, Fe II Emission Line Stars, and Other Supergiants
An increasing number of non-terminal eruptions are being found in the numerous surveys for optical transients. Very little is known about these giant eruptions, their progenitors and theirExpand
MN112: a new Galactic candidate Luminous Blue Variable
We report the discovery of a new Galactic candidate Luminous Blue Variable (cLBV) via detection of an infrared circular nebula and follow-up spectroscopy of its central star. The nebula, MN112, isExpand

In this series of papers we have presented the results of a spectroscopic survey of luminous stars in the nearby spirals M31 and M33. Here, we present spectroscopy of 132 additional stars. Most haveExpand
Search for LBV candidates in the M33 galaxy
A total of 185 luminous blue variable star (LBV) candidates with V<18·m 5 are selected based on the results of aperture photometry. The primary selection criterion is that the prospective candidateExpand
