Transit and Eclipse Predicting
This tool computes times of exoplanet transits and secondary eclipses which are visible at a selected observatory. Please login or register using the link at the bottom of the page. To run this tool, click on Plots.
Eclipses: We have identified 32 priority targets which may have eclipse depths between 4.8e-4 (WASP-19b) and 6.5e-5 (KELT-3b). These targets are listed on the top of the drop-down menu (Plots) in the order of decreasing of the eclipse depth. We estimated that perhaps about 10 observations of eclipses are needed in the same filter to average the noise and detect the signal. Blue filter is preferred.
Transits: The same targets are suggested for transit observations when possible with several filters: blue, visual, red. Long-term multi-color monitoring of stellar activity (once a night) is also desirable. In fact, it is essential to have these measurements for proper interpretation of the eclipse and transit depths.
Polarimetry: The same targets are suggested for polarimetric observations, but most of them are fainter than 10mag, so only large telescopes are useful. Detecting eclipses will justify observing programs on large telescopes with our polarimeters.
Transit and Eclipse Visibility
Please select target, observatory, months, year, and a type of planet conjunction. Transit and eclipse phases are calculated using orbital parameters from the NASA Exoplanet Archive. If transits or eclipses are found, you will get visibility plots for each and a file with the list of transit/eclipse dates and times.
