Far-infrared Herschel PACS imaging and spectroscopic observations of the nebula around the luminous blue variable (LBV) star AG Car have been obtained along with optical imaging in the Hα+[N ii] filter. In the infrared light, the nebula appears as a clumpy ring shell that extends up to 1.2 pc with an inner radius of 0.4 pc. It coincides with the Hα nebula, but extends further out. Dust modeling of the nebula was performed and indicates the presence of large grains. The dust mass is estimated to… 
Herschel observations of the nebula M1-67 around the Wolf-Rayet star WR 124
Infrared Herschel imaging and spectroscopic observations of the nebula M1-67 around the Wolf-Rayet star WR 124 have been obtained along with optical imaging observations. The infrared images reveal a
Exploring the multifaceted circumstellar environment of the luminous blue variable HR Carinae
We present a multi-wavelength study of the Galactic Luminous Blue Variable HR Carinae, based on new high resolution mid-infrared (IR) and radio images obtained with the Very Large Telescope (VLT) and
A massive nebula around the luminous blue variable star RMC 143 revealed by ALMA
The luminous blue variable (LBV) RMC 143 is located in the outskirts of the 30 Doradus complex, a region rich with interstellar material and hot luminous stars. We report the 3σ sub-millimetre
The Luminous Blue Variable RMC 127 as Seen with ALMA and ATCA
We present ALMA and ATCA observations of the luminous blue variable RMC 127. The radio maps show for the first time the core of the nebula and evidence that the nebula is strongly asymmetric with a
Tracing back the evolution of the candidate LBV HD 168625
Context. The luminous blue variable phase is a crucial transitory phase that is not clearly understood in the massive star evolution. Aims. We have obtained far-infrared Herschel /PACS imaging and
The luminous blue variable HR Carinae has a partner. Discovery of a companion with the VLTI
Luminous blue variables (LBVs) are massive stars caught in a post-main sequence phase, during which they lose a significant amount of mass. Since, on one hand, it is thought that the majority of
New ATCA, ALMA and VISIR observations of the candidate LBV SK -67 266 (S61): the nebular mass from modelling 3D density distributions
We present new observations of the nebula around the Magellanic candidate Luminous Blue Variable S61. These comprise high-resolution data acquired with the Australia Telescope Compact Array (ATCA),
A warm molecular ring in AG Car: composing the mass-loss puzzle
We present APEX observations of CO J=3-2 and ALMA observations of CO J=2-1, 13CO J=2-1 and continuum toward the galactic luminous blue variable AG Car. These new observations reveal the presence of a
Wind-envelope interaction as the origin of the slow cyclic brightness variations of luminous blue variables
Luminous blue variables (LBVs) are hot, very luminous massive stars displaying large quasi-periodic variations in brightness, radius, and photospheric temperature on timescales of years to decades.
The canonical Luminous Blue Variable AG Car and its neighbor Hen 3-519 are much closer than previously assumed
The strong mass loss of Luminous Blue Variables (LBVs) is thought to play a critical role in massive-star evolution, but their place in the evolutionary sequence remains debated. A key to


We present mid-IR observations of the Galactic Luminous Blue Variable (LBV) HR Car and its associated nebula carried out with the Spitzer Space Telescope using both Infrared Array Camera and Infrared
Ejected Nebulae as Probes of the Evolution of Massive Stars in the Large Magellanic Cloud
We present new Hubble Space Telescope (HST) Faint Object Spectrograph (FOS) and ground-based long-slit spectroscopic observations of the nebulae around the two LMC luminous blue variables (LBVs) R127
Chemical composition and origin of nebulae around luminous blue variables
We use the analysis of the heavy element abundances (C, N, O, S) in circumstellar nebulae around luminous blue variables to infer the evolutionary phase in which the material has been ejected. We

The AG Carinae Nebula -- Bigger than ever?
Abstract. Analysis of deep H α images show that the LBV nebula aroundAG Car has a larger, cone-like extension to the north which is about the sizeof the central nebula but expands faster. This cone
A massive parsec-scale dust ring nebula around the yellow hypergiant Hen 3-1379
On the basis of far-infrared images obtained by the Herschel Space Observatory, we report the discovery of a large and massive dust shell around the yellow hypergiant Hen3-1379 . The nebula appears
The AG Carinae nebula: abundant evidence for a red supergiant progenitor?
AG Carinae is a massive, evolved supergiant which is thought to be in transition from an 0 star to a Wolf-Rayet (WR) star and is currently identified as a luminous blue variable (LBV) with 10gLlL0 =
