Four canonical LBVs in the Milky Way were of special interest for Smith and Stassun, namely:
4顆高量亮度的藍變光星 AG Car, HR Car, HD 168607 and Hen 3-519 (an LBV candidate).
"Here, we report direct distances and space motions of four canonical Milky Way LBVs—AG Car, HR Car, HD 168607, and (the LBV candidate) Hen 3-519 – whose parallaxes and proper motions have been provided by the Gaia first data release," the researchers wrote in the paper.
