Aims. We present a spectroscopic analysis of MWC 314, a luminous blue variable (LBV)
candidate with an extended bipolar nebula. The detailed spectroscopic variability is …

MWC 314 is a bright candidate luminous blue variable (LBV) that resides in a fairly close
binary system, with an orbital period of 60.753±0.003 d. We observed MWC 314 with a …

We present interferometric observations with the Atacama Large Millimeter Array (ALMA) of
the free–free continuum and recombination line emission at 1 and 3 mm of the Red Square …

We present the results of optical high-resolution and near-infrared low-resolution
spectroscopy and multicolour optical and near-infrared photometry of the emission-line star …

We present an analysis of an extensive set of spectroscopic observations of the mysterious
early-type binary BD+ 40 4220. A new orbital solution is derived from the radial velocities of …

In this note, we show that the ultraviolet and optical spectroscopic variability of this unique
symbiotic star can be understood in terms of a time variable collimated stellar wind with a …

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 …

We report a long-term high-resolution spectroscopic monitoring program of LBVs and
candidate LBVs with Mercator-HERMES. Based on 7 years of data, we recently showed that …

The young stellar object MWC 297 is an embedded B1. 5Ve star exhibiting strong hydrogen
emission lines and a strong near-infrared continuum excess. This object has been observed …

We present the first systematic spectropolarimetric study of Luminous Blue Variables (LBVs)
in the Galaxy and the Magellanic Clouds, in order to investigate the geometries of their …
