Welcome to TESS Asteroseismic Science Operations Center
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.
12th Nov 2018: Help for reading FITS files
We have added some small code-snippets on how to load in FITS files in various languages (Python, IDL, Matlab) under "Documentation and Help".
In the future, the plan is that the TASOC website will also provide ASCII versions of light curves, as an alternative to the FITS files. These do use more disk-space than their FITS counterparts and will contain less information, so we would recommend to use FITS if possible.
6th Nov 2018: Second data release
We are pleased to announce the second release of TESS data for asteroseismology from the TASC Coordinated Activity T'DA.
For this release 79 TOI targets from TESS sectors 1 and 2 have been analysed. These targets are primarily of interest to TASC WGs 1+2 (planet hosting stars and solar-like oscillators). Please note that this data is optimized for asteroseismology, and therefore the planetary transit signals have been intentionally removed.
19th Oct 2018: List of TOIs
We have added a "live" list of the TESS Objects of Interest in the sidebar to the left. Here you can find a complete list of all TOIs that is continuously updated as new TOIs are released or updated.
