متن کاملDusty ring nebulae around new candidate Luminous Blue Variables
We report on the discovery of a further two ring nebulae in the Midcourse Space Experiment (MSX) Galactic Plane Survey; G24.73+0.69 and G26.47+0.02. Morphologically, both appear similar to the nebulae found around the Luminous Blue Variable (LBV) candidates G79.29+0.46 and Wra 17-96. A central, unresolved point source was identified in both cases – positional coincidence with the star StRS 237 ...
متن کاملA spectroscopic analysis of the Luminous Blue Variable candidate WRA 751 ?
We present spectroscopic observations of the LBV candidate WRA 751 taken at different epochs during the period 1989−1995. These observations are used to monitor the temporal evolution of the spectrum over the last few years. In addition, we identify most of the emission and absorption features in the spectral range 4100−9250 Å and obtain a new determination of the extinction towards this source...
متن کاملA Second Luminous Blue Variable in the Quintuplet Cluster.
H- and K-band moderate-resolution and 4 µm high-resolution spectra have been obtained for FMM 362, a bright star in the Quintuplet Cluster near the Galactic center. The spectral features in these bands closely match those of the Pistol Star, a luminous blue variable and one of the most luminous stars known. The new spectra and previously obtained photometry imply a very high luminosity for FMM ...
متن کاملRadio images of four luminous blue variable stars
We have used the Australia Telescope Compact Array to image four southern luminous blue variable stars: AG Car, He3-519, HR Car and WRA 751, at wavelengths of 3 and 6 cm, and resolutions of 1 and 2 arcsec respectively. With the partial exception of HR Car, all radio images show an unresolved stellar core surrounded by a large ionized gaseous nebula, and agree well with published Ha and [N II] o...
