The Debris Disk Host β Piscis Austrinus is a Rapidly Rotating Star Seen Nearly Pole-On
AAS Nova · By Kerry Hensley ·
The Brief
- A new analysis of the debris disk host star Beta Piscis Austrini finds it is rapidly rotating and seen nearly pole-on.
- The spectroscopic method indicates the star's poles are 24% hotter than its equator.
- The results are reported by Colin J. Kane et al. in ApJ 1006, 228 (2026).
Why it matters
It shows that spectroscopy can be used to determine properties of rapidly rotating stars seen nearly pole-on, a viewing geometry that complicates standard analysis.
