Planetensuche / hunting for exoplanets  

My personal hunt for exoplanets on Planet Hunters TESS

There are many possible transits in the pipeline to check, if they are false positives or not...
All marked transits are available on MAST: findings by users

Tests that must be passed successfully:
  • significant enouth in binned data
  • no wheel motion/momentum dump
  • estimated planet parameters possible (radius, orbit period)
  • centroid test
  • background flux test
  • in-out-transit flux test
  • nearby star test
  • aperture test
  • pixel plot test
  • phase folded, if there are multi-transits
  • at least 3 transits observed for a good orbit model
  • and at the end confirmed by radial velocity method

  • Abbreviations:
  • APC = Ambiguous Planet Candidate
  • AU = astronomical unit (~149.6 million km)
  • BEB = Blended Eclipsing Binary
  • BLS = Box Least Squares (analysis)
  • BTJD = Barycentric-corrected TESS Julian Date
  • CTL = Candidate Target List (highest priority targets in the TIC)

  • KOI = Kepler Object of Interest
  • LC = light curve
  • NEB = nearby eclipsing binary
  • PC = planet candidate
  • PHT = Planet Hunters TESS
  • QLP = Quick-Look Pipeline
  • RUWE = renormalised unit weight error for astrometry (~1 = single star, >=2 = non-single; additional to astrometric excess noise significance, if >2 then binary system possible)
  • RV = radial velocity
  • SSO = solar system object, e.g. asteroid
  • TCE = A Threshold-Crossing Event (TCE) is a sequence of transit-like features in the flux time series of a given target that resembles the signature of a transiting planet to a sufficient degree that the target is passed on for further analysis.
  • TESS = Transiting Exoplanet Survey Satellite
  • TFOP = TESS Follow-up Observing Program
  • TIC = TESS Input Catalog
  • TNO = Trans Neptun Object
  • TOI = TESS Object of Interest
