3rd TESS Data for Asteroseismology workshop 2017

The idea with the TESS Data for Asteroseismology (T'DA) workshop series is to prepare for an efficient facilitation of high quality data for asteroseismology from the future NASA TESS mission, and this to the whole of the TESS Asteroseismic Science Consortium (TASC).

TESS will observe close to the full sky within its 2 year nominal mission, with full frame images (FFIs) taken every ~30 minutes. This will result in a data rate unlike that of Kepler or CoRoT, and with new data arriving every ~27 days. The TASC Coordinated Activity (CA) "TESS Data for Asteroseismology" (T'DA; formerly known as "Working Group 0" (WG0)) is tasked with delivering analysis ready light curves for all of TASC, hence encompassing many different types of stars, and for all targets observed, including those in FFIs. This calls for optimised pipelines in terms of the data rate, and light curve preparation that can deal with many different types of objects.

With the T'DA workshop series we want to bring together people from TASC with experience from, e.g., Kepler or CoRoT in order to test different approaches to the tasks at hand. The goal is to end out with a robust and optimised pipeline for TESS data preparation. 

The third workshop in the series, T'DA3: "Stellar classification with TESS", will take place at KU Leuven, BE, on 6-8 December 2017. The goal of the workshop is to test and compare different methods for classifying different stellar types. Remote participation will be possible during the workshops.

Simulated light curves will be prepared before T'DA3 (early November) for a range of different stellar types, magnitudes, cadences, observing durations, etc. A link to the data can be found under the "Simulated data" sub page, or via the T'DA wiki on tasoc.dk. Participants with classification (or light curve correction) codes are strongly encouraged to apply these to the simulated data and to have results ready shortly before the workshop to allow us to prepare a comparison. Based on everyone's results we are hopeful that an optimum approach can be found for the classification of all stellar types of interest to asteroseismology.
