for anyone that wants to participate in exoplanet hunting, and wants to use transit method, you can register here and start looking

already found these 2 potential planets potently lurking around TIC 115072732
(the 2 outer planets are from planet C and the 2 inner ones are from planet)
TIC 115072732 lightcurve (1).png


unconfirmed planet b orbit is ~10 days
unconfirmed planet c orbit is ~23 days

going off of that, these are the orbits of those 2 unconfirmed exoworlds i got

quite fun looking for these things

It seems that I already have an idea for my next college project. I hope no one of my groupmates will decided to do it. Thank you very much!

this was a false +, bummer

Added after 20 seconds:
may turn these into fictional planets

Relevant new paper: A SuperWASP Light Curve Displaying a Single Long-duration Transit: A Jupiter Size Exoplanet in a Very Distant Orbit?

This candidate was found by Zooniverse volunteers (including trappistplanets) on a different project, SuperWASP: Black Hole Hunters (discussion thread). It could potentially be a large planet or brown dwarf in a very wide orbit (~205 AU, ~2240 years) around the star, which would make it the longest-period transiting planet known. The chance of detecting such a transit is about 1 in 36 million! Another possibility not discussed in the paper is that of a free-floating object that passed in front of a background star (which has been suggested for the similar candidate J1407b).

SSC code assuming a star-orbiting object:

Code: Select all

"1SWASP J182438.34+302546.0 b:b:(unconfirmed)" "TYC 2623-1439-1"
{
   Class "planet"
   Texture "browndwarf.*" # assuming a young object
   Emissive true
   Color [ 1 0.5 0.5 ]
   Radius 128686
   EllipticalOrbit {
      Epoch 2453197.9
      Period 2240
      SemiMajorAxis 205
      Inclination 87.55
      AscendingNode 275.65
      ArgOfPericenter 143.75 # apparently needed for transit time to work??
      MeanAnomaly 90
   }
   UniformRotation {
      Period 10 # guess
      Inclination 87.55
      AscendingNode 275.65
   }

}


Update 2022-06-22: The apparent transit turns out to be an artifact. There isn't a planet here.

thing has sutch a long period its near impossible with current tech to prove this planet, because it will take another ~2240 years for us to see the transit again
