TASOC
Welcome to TESS Asteroseismic Science Operations Center
Important: The TASOC web pages are not actively maintained! Please be aware when using them.
Data download does not work! TASC review and the mail service should still work.
The star search works, but is somewhat limited (to reduce the strain on our database). Please let us know if you have requests for a potential future ASC archive.
The TESS Asteroseismic Science Operations Center (TASOC) provides asteroseismological data from the NASA TESS mission to astronomers who are members of the TESS Asteroseismic Science Consortium (TASC). It is also the platform used to facilitate the international collaborations within TASC.
If you are a member of TASC, please log in below...
In order to have access to TASOC you have to be a member of TASC. Please see the "New TASC member" page on how to become a member.

31st Mar 2025: Service window
Due to maintenance work on our computer system, TASOC will be operating with limited functionality on 31 March 2025. Thank you for your understanding.
16th Jan 2024: Reducing Data Search Options
As a step in the discontinuation of the maintenance of the TASOC database, it will soon no longer be possible to access data products generated by the TESS mission via the Data Search tab. We refer users to the MAST archive where all these data are available.
The TASOC/T'DA reduced data will still be available (and can also be accessed via the Bundles tab).
4th Apr 2023: TASC GI Cycle 6 Coordination
The TESS Guest Investigator (GI) office is soliciting proposals for the second year of the second extended mission. Like in the first extended mission TASC does not have reserved 2-minute and 20-second cadence targets, and hence GI proposals from TASC are important to ensure the selection of targets for asteroseismology. More information on the GI program (including a proposal template) can be found here.
The proposal deadline for Cycle 6 is Friday, April 14 2023, at 4:30pm US Eastern Time.
Similar to previous cycles, we set up a GI coordination page on the TASOC Wiki to coordinate the submission of TASC GI proposals:
https://tasoc.dk/gi/Cycle6
If you are planning to submit a GI proposal and would like to coordinate, we recommend the following steps:
- Add your proposal information on the Cycle 6 GI coordination page (https://tasoc.dk/gi/Cycle6)
- Submit your target lists on the TASC Cycle 6 Proposal Submission Page. Note that 2-min and 20-sec target lists need to be submitted separately.
If you have any questions or need help with putting together TASC GI proposals please don’t hesitate to contact the co-chairs of the TASC GI Coordinated Activity (Dan Huber and Marc Pinsonneault).
