TESS Data for Asteroseismology workshop

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 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 first workshop in the series, T'DA1: "From Pixels to Light Curves",  will take place at Birmingham University, UK, on 31 October - 2 November; T'DA1 will deal specifically with the extraction of light curves from simulated TESS pixel data. The second workshop (T'DA2) is planned to take place in Aarhus during 2017 and will deal with light curve correction of different types of objects. Remote participation will be possible during the workshops.

Simulated TESS pixel data will be prepared before T'DA1 for a range of different fields --- FFIs, regions containing clusters, 20 sec/2 min postage stamps, etc. A link to the data can be found under the "Simulated data" sub page, or via the WG0 wiki on tasoc.dk. We aim for participants to analyse as much of the simulated data before the workshop to allow for a better comparison of different methods.

We know that not all participants will have tools ready for such an analysis, but for those who do we will include a presentation of the method and results in the workshop programme.
