Short-term variability and mass loss in Be stars IV. Two groups of closely spaced, approximately equidistant frequencies in three decades of space photometry of Puppis (B7-8 IIIe)
D. Baade, A. Pigulski, Th. Rivinius +13
In early-type Be stars, groups of nonradial pulsation (NRP) modes with numerically related frequencies may be instrumental for the release of excess angular momentum through mass-e…
BRITEning up the Be Phenomenon
D. Baade, Th. Rivinius, A. Pigulski +13
Observations of 25 Ori much expand the picture derived of other early-type Be stars with BRITE and SMEI. Two instead of one difference frequencies rule the variability: (a) The low…
Pulsations and outbursts in Be stars: Small differences - big impacts
D. Baade, Th. Rivinius, A. Pigulski +12
New high-cadence observations with BRITE covering many months confirm that coupled pairs of nonradial pulsation modes are widespread among early-type Be stars. With the difference…
Dissecting a SN impostor's circumstellar medium: MUSEing about the SHAPE of eta Car's outer ejecta
A. Mehner, W. Steffen, J. H. Groh +10
Aims. The structural inhomogeneities and kinematics of massive star nebulae are tracers of their mass-loss history. We conduct a three-dimensional morpho-kinematic analysis of the…
Eta Carinae's 2014.6 Spectroscopic Event: Clues to the Long-term Recovery from its Great Eruption
A. Mehner, K. Davidson, R. M. Humphreys +9
Aims. Every 5.5 years eta Car's light curve and spectrum change remarkably across all observed wavelength bands. We compare the recent spectroscopic event in mid-2014 to the events…
Broad-band Spectroscopy of the Ongoing Large Eruption of the Luminous Blue Variable R71
A. Mehner, D. Baade, T. Rivinius +4
The Luminous Blue Variable (LBV) R71 is currently undergoing an eruption, which differs photometrically and spectroscopically from its last outburst in the 1970s. Valuable informat…
