What are TOI Releases?
TOI Releases are notifications to the astronomical community so that preliminary planet candidates may be followed up as soon as possible following official data release. Sign up for notifications of new TOIs here.
What data is available to support TOI Releases?
MAST hosts SPOC data products for released objects from the NASA SPOC pipeline (link).
How many TOIs will there be?
Each sector typically yields 80 TOIs. Check the latest count here.
Where do I find more information on each column in the TOI Catalog?
Start with the TOI Catalog release notes, on this page.
For an in-depth description of the TOI Catalog and the TOI process, view Guerrero et al., 2021
Are false positives expected?
In any transit survey false positives are expected; follow-up observations are important and necessary for identifying false positives.
Can I submit my own planet candidates for TOI Releases?
If you find a planet candidate submit it to ExoFOP-TESS. Your candidate will become a community TOI (cTOI). The candidate will be reviewed by the TESS TOI Team where if it meets the team standard it will be assigned TOI number.
What is the difference between TOI Releases and TESS Alerts?
TESS Alerts were TOIs from early sectors released before public data were available on MAST. TOI releases are the current standard form for delivering TOIs to the community, and come out after the public release of TESS data on MAST.
