Discussion Overview
The discussion revolves around the upcoming occultation of the star Betelgeuse by an asteroid, exploring the implications for both the asteroid and the star. Participants discuss the rarity of such events, the observational opportunities they present, and the potential scientific insights that could be gained, particularly regarding Betelgeuse's characteristics.
Discussion Character
- Exploratory
- Technical explanation
- Conceptual clarification
- Debate/contested
Main Points Raised
- Some participants note that occultations are rare and provide unique opportunities to study both the asteroid and Betelgeuse.
- There is discussion about the timing and visibility of the event, with specific details about the locations where it can be observed.
- Some participants express uncertainty about what can be learned about Betelgeuse during the occultation, questioning the value of new observations given existing Hubble data.
- Others suggest that the variation in brightness during the occultation could yield information about the star's corona and surface features.
- There are inquiries about the differences between transits, eclipses, and occultations, with some participants admitting confusion over these terms.
- One participant mentions the possibility of using spectroscopy to gather data on magnetic fields, though they express skepticism about the feasibility of this approach.
- Some participants raise questions about the frequency of stars being eclipsed or occulted by various objects, including satellites and aircraft, suggesting it could be a Fermi problem.
- There are references to previous studies that have mapped Betelgeuse's convective cells, indicating ongoing interest in the star's surface dynamics.
- Later posts confirm that the event occurred, but express disappointment in the lack of spectacular visual data and the lengthy analysis process required for results.
Areas of Agreement / Disagreement
Participants generally agree that the occultation is a significant event for observational astronomy, but there is no consensus on the specific insights that can be gained about Betelgeuse. Multiple viewpoints exist regarding the value of the observations and the nature of the data that can be collected.
Contextual Notes
Some participants express uncertainty about the scientific outcomes of the occultation, particularly in relation to existing data from Hubble. There is also a discussion about the limitations of current observational technology in resolving certain features of Betelgeuse.
