Overview

Predictions uncover stellar occultations by Haumea, highlighting the 2026 event significance for observations.

Key Points

  • The aim is to predict and analyze stellar occultations by Haumea to enhance observational opportunities.
  • Predicted stellar occultations for various stars through 2030.
  • Detailed geometry analysis of the 4 May 2026 event.
  • Derivation of Haumea’s sky-plane shadow width.
  • Reliability analysis considering the star's RUWE.
  • Speckle imaging to identify companion stars.
  • Identified eleven stellar occultation events by Haumea until 2030.
  • Sky-plane shadow width calculated at 2224 ± 30 km, larger than expected.
  • Companion star identified at ∼0.12 arcsec affecting main star path.
