On the population of galactic Luminous Blue Variables.

CLARK J.S., LARIONOV V.M. and ARKHAROV A.

Abstract (from CDS):

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 of G24.73+0.69, a luminous mid-B supergiant associated with a dusty ejection nebula. We find that prior to 2003 September G24.73+0.69 exhibited low amplitude (ΔJHK∼0.4mag) variability, but in the ∼200-day period between 2003 September-2004 April it abruptly brightened by ∼0.7mag in the broadband J filter. Subsequently, a further ∼0.4mag increase was observed between 2004 April-October, resulting in an overall difference of ∼1.1mag between (current) photometric mimimum and maximum; similar variability also being observed in the H and K bands. In light of the numerous recent IR studies of the galactic hot star population we also compile an updated census of confirmed and candidate galactic LBVs, reporting 12 and 23 members respectively for each class. Finally, we utilise this new census to construct an H-R diagram for the galactic LBV population, resulting in a striking confirmation of the LBV-minimum light strip.
