Welcome to TESS Asteroseismic Science Operations Center

The TASOC web pages are not being maintained - use at your own risk!

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.


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:

If you are planning to submit a GI proposal and would like to coordinate, we recommend the following steps:

  1. Add your proposal information on the Cycle 6 GI coordination page (https://tasoc.dk/gi/Cycle6)
  2. 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).

16th Mar 2023: T'DA11 Announcement

The TESS Data for Asteroseismology (T'DA) workshop series focused on developing a TESS pipeline optimized for asteroseismology by bringing together people from across TASC to brainstorm, compare, and implement ideas for data preparation.

We would like to restart the T'DA workshop series with T'DA 11, at Konkoly Observatory, Budapest, Hungary from 24-26 May. Remote participation will be available, but we encourage in-person attendance when possible.
