Atomium: A high-resolution view on the highly asymmetric wind of the AGB star Pi1 Gruis. I. First detection of a new companion and its effect on the inner wind
Ward Homan, Miguel Montarges, Bannawit Pimpanuwat +35
The nebular circumstellar environments of cool evolved stars are known to harbour a rich morphological complexity of gaseous structures on different length scales. A large part of…
Betelgeuse scope: Single-mode-fibers-assisted optical interferometer design for dedicated stellar activity monitoring
Narsireddy Anugu, Katie M. Morzinski, Josh Eisner +12
Betelgeuse has gone through a sudden shift in its brightness and dimmed mysteriously. This is likely caused by a hot blob of plasma ejected from Betelgeuse and then cooled to obscu…
(Sub)stellar companions shape the winds of evolved stars
L. Decin, M. Montargès, A. M. S. Richards +32
Binary interactions dominate the evolution of massive stars, but their role is less clear for low- and intermediate-mass stars. The evolution of a spherical wind from an asymptotic…
A detailed view on the circumstellar environment of the M-type AGB star EP Aquarii I. High-resolution ALMA and SPHERE observations
Ward Homan, Emily Cannon, Miguel Montargès +3
Cool evolved stars are known to be significant contributors to the enrichment of the interstellar medium through their dense and dusty stellar winds. High resolution observations o…
Spatially Resolved Ultraviolet Spectroscopy of the Great Dimming of Betelgeuse
Andrea K. Dupree, Klaus G. Strassmeier, Lynn D. Matthews +9
The bright supergiant, Betelgeuse (Alpha Orionis, HD 39801) experienced a visual dimming during 2019 December and the first quarter of 2020 reaching an historic minimum 2020 Februa…
Imaging the expanding knotty structure in the close environment of the LBV star Carinae
F. Millour, E. Lagadec, M. Montargès +13
~Car is one of the most massive stars in the Galaxy. It underwent a massive eruption in the 19th century, which produced the impressive bipolar Homunculus nebula now surrounding…
