4th TESS Data for Asteroseismology workshop 2018

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. 

T'DA4: "Preparing for first light"

The fourth workshop in the series, T'DA4: "Preparing for first light", will take place at the Stellar Astrophysics Centre, Aarhus University, DK, on 16-18 July 2018 (the week after the TASC4/KASC11 conference). The primary goal of the workshop is to test and compare different methods for classifying different stellar types, but other aspects of the T'DA work will also be discussed.

Simulated light curves has been prepared 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 before the workshop.

Important information

Other important information about the workshop:

  • This meeting is technically not connected to the TASC4/KASC11 meeting (which takes place the week before).
  • We will have two coffee breaks per day, one in the morning and another one in the afternoon, and we will cover your lunch.
  • To relax a bit, we are organizing a barbecue on Tuesday afternoon. Please let us know if you don't want to take part in it, or if you are vegetarian/vegan. It will be covered by us, too.
  • We will make a tentative program available before the meeting, but no one has to prepare any talks. We aim at a informal workshop where we work and present results obtained while we work. Of course if you want to present some results, please let us know by the end of this month to organize space in our schedule for your presentation.
