On the Gaia DR2 distances for Galactic Luminous Blue Variables
Nathan Smith, Mojgan Aghakhanloo, Jeremiah W. Murphy +3
We examine parallaxes and distances for Galactic luminous blue variables (LBVs) in Gaia DR2. The sample includes 11 LBVs and 14 LBV candidates. For about half of the sample, DR2 di…
