Core Features & Modules

πŸͺ Exoplanet & Stellar Catalog Database

  • Vast Catalogs: Embedded database with up-to-date exoplanet discoveries (NASA Exoplanet Archive, Gaia DR3, TESS TOI/CTOI, Kepler, SIMBAD).
  • Broad Scope: Explore exoplanets, galaxies, dwarf planets, asteroids, and variable stars (AAVSO, VSX).
  • Habitability Analysis: Calculate Earth Similarity Index (ESI) and filter by circumstellar habitable zones (Kopparapu 2013 models).
  • Binary Star Matching: Cross-reference catalog data to identify binary and multiple stellar systems.

πŸ“Š Data Visualization & Analytics

  • Over 70 Interactive Charts: Compare planetary masses, radii, orbital periods, discovery methods, and stellar spectral types (including HR Diagrams).
  • Estimation Tools: Built-in calculators for estimating stellar radius and mass based on observational parameters.

πŸ›°οΈ PLATTE – Transit Vetting & Light Curve Analysis

  • TESS Light Curves & Photometry: Direct MAST download of TESS SPOC and QLP light curves and Target Pixel Files (TPF) with noise filtering and stellar pulsation removal.
  • Transit Detection & Modeling: Signal search via BLS and TLS algorithms (including single-transit detection), Mandel & Agol transit modeling, and Transit Timing Variations (TTV).
  • 24 Vetting Tests in PDF Report: Comprehensive false-positive vetting (odd-even test, secondary eclipses, difference imaging, centroid motion, background blends, ...) consolidated into a detailed PDF report.
  • Scientific Exports: Seamless export to Pyaneti for MCMC transit modeling, TPF FITS cutouts, and structured transit parameter tables.

🌌 Interactive Star Map & Simulations

  • Dynamic Sky Map: Interactive celestial map highlighting constellations, deep-sky objects, and exoplanet host stars.
  • Orbit Simulator: Observe exoplanets in realistic orbits around their host stars or build custom planetary configurations.
  • Observing Planner: Tracks sunrise/sunset, moon phases, comets, and night sky quality (Bortle & SQM metrics).

πŸŽ“ Education & Extras

  • Astronomy Quiz: Test your knowledge about space, distances, and planetary facts with a built-in educational quiz module.
  • Formula Collection: A handy reference section for common astronomical formulas and physical calculations.
  • History of Exoplanet Hunting: Detailed timelines and information regarding milestones in exoplanet research (View timeline β†’).

βš™οΈ Technical Architecture

  • Offline First: Fully standalone execution at the telescope without requiring internet connectivity.
  • Modern Java: Built with Java 21 (LTS) & JavaFX for responsive performance and fluid rendering.
  • Cross-Platform: Runs smoothly across Windows, Linux, and macOS.
  • Multilingual UI: Supports German, English, French, Spanish, and Italian.
