We conduct a rigorous examination of the nearby red supergiant Betelgeuse by drawing on the synthesis of new observational data and three different modeling techniques. Our observational results include the release of new, processed photometric measurements collected with the space-based SMEI instrument prior to Betelgeuse's recent, unprecedented dimming event. We detect the first radial overtone in the photometric data and report a period of $185\pm13.5$ d. Our theoretical predictions include…

The Betelgeuse Project. III. Merger Characteristics
• Physics, Geology
• 2020
We previously proposed that Betelgeuse might have been spun up by accreting a companion of about 1 solar mass. Here we explore in more detail the possible systematics of such a merger and a larger
The Photospheric Temperatures of Betelgeuse during the Great Dimming of 2019/2020: No New Dust Required
• Physics, Geology
• 2020
The processes that shape the extended atmospheres of red supergiants (RSGs), heat their chromospheres, create molecular reservoirs, drive mass loss, and create dust remain poorly understood.
Early warning signals indicate a critical transition in Betelgeuse
• Physics
Astronomy & Astrophysics
• 2020
Context.Critical transitions occur in complex dynamical systems when the system dynamics undergoes a regime shift. These can often occur with little change in the mean amplitude of the system
Stellar Models of Betelgeuse Constrained Using Observed Surface Conditions
• Physics
The Astrophysical Journal
• 2022
We study stellar models for Betelgeuse using the HR diagram and surface abundances as observational constraints. Previous studies on Betelgeuse have not systematically investigated the surface
The Great Dimming of Betelgeuse seen by the Himawari-8 meteorological satellite
• Physics, Environmental Science
Nature Astronomy

Betelgeuse, one of the most studied red supergiant stars1,2, dimmed in the optical range by ~1.2 mag between late 2019 and early 2020, reaching a historical minimum3–5 called ‘the Great Dimming’.
Online triggers for supernova and pre-supernova neutrino detection with cryogenic detectors

. Supernovae (SNe) are among the most energetic events in the universe still far from being fully understood. An early and prompt detection of neutrinos is a one-time opportunity for the realization
Episodic Gaseous Outflows and Mass Loss from Red Supergiants
• Physics
The Astronomical Journal

The red hypergiant VY CMa and the more typical red supergiant (RSG) Betelgeuse provide clear observational evidence for discrete, directed gaseous outflows in their optical and infrared imaging,
Numerical Simulations of Convective Three-dimensional Red Supergiant Envelopes

The curious case of Betelgeuse
Betelgeuse is the nearest red supergiant, one of the brightest stars in our sky, and statistically speaking it would be expected to be ”typical”. Yet it exhibits many features that seem ”curious”, to
