Exoplanet Watch Results
These results in the table below are automatically compiled from data submitted by Exoplanet Watch participants. This process is done using Citizen Initiated Transit Information Survey Enabling NASA Science (CITISENS), a fully-automated pipeline built upon the DAWGIE pipeline framework. It regularly scrapes the AAVSO Exoplanet Database , ingests any new or updated data, fits each transit timeseries with a model lightcurve, and then calculates new ephemerides and orbital periods for every target submitted to the Exoplanet Watch project. CITISENS runs weekly in early AM hours PST, and data is published the same day. Priors listed in the below table are collected from the NASA Exoplanet Archive. Feedback, concerns or bug reports? Please email exoplanetwatch@jpl.nasa.gov .

What's in a Name?
Where do the names of the exoplanets come from? What does the "b" mean?
If you're new to studying exoplanets, you may wonder why the Planet Name column on the left side of the spreadsheet below has such unusual names for the exoplanets we study. Exoplanets are named after the telescope or survey that found them. Exoplanet TrES-2 b orbits its host star, TrES-2. Here's a link that explains more about it: How do Exoplanets get their Names?
Where's my data?
Find your light curve!
A sample light curve of the transiting hot Jupiter exoplanet HAT-P-32 b as observed with a 6-inch (15.24-cm) MicroObservatory telescope located in Tucson, Arizona.
If you have processed a light curve and uploaded it to the American Association of Variable Star Observers (AAVSO), click on the name of the exoplanet you studied in the table below and search for your AAVSO observer code to see the light curve that you contributed to the global body of scientific research about your exoplanet. You can see all of the other light curves contributed by other citizen scientists, too! Each exoplanet listed on the table below has an interactive artist's concept you can explore once you click on the name of the exoplanet.

Most Frequently Reduced Targets
Reductions published in the six months preceding the September 6, 2025 feed file (Apr 2025 – Sep 2025).
Reduction months are measured from 51 reduction feeds published 2025-04-03 to 2025-09-06: each observation is credited to the first feed it appeared in. The 2025-03-30 feed, published before this window, establishes the starting point, so the 7950 observations that already existed are excluded rather than counted in the first month.
