#tasc5 Amhrán: share an Irish language song that you love to hear. #TascAnLae #LetsLearnIrish https://t.co/KLQmCvZXpL
The #Tasc5 conference is officially over. It was a week of high level scientific discussions and gave a first strong impression of what we can expect from the @TESSatMIT space telescope to come in the future.
Many thanks to @StellarTayar and others for tweeting #TASC5 -- almost felt like I was there. See some of you next week @TessSciCon1
@ProfSaraSeager TOI search, many diagnostics. AI good, but not enough training data. Metrics better. 993 tois, nearby. Flares important, simultaneous multiband. Do Earths orbit in plane? If so, use cubesats to search best edge on stars.Tess also sees comets and supernova. #Tasc5
@ProfSaraSeager closes #tasc5 with a bridge talk to next week's TESS #tsc1 conference, with a throwback to her early days observing Polaris, a Cepheid, from the David Dunlap Observatory.
C. Gehan inclination important for dynamics, stellar formation. Use giant mixed modes (easier). Used stretched period diagram, ID modes above noise. Get distribution of i mostly isotropic. See dips where mode hard to see. Cluster i problem come from clump stars? Rgb agree? #Tasc5
M. Nielsen lambda2 Fornacis known RV planet host in tess. Seismo not pretty but get modes. Collapses range of star params. use Kima to update planet params. Seismo gives some inclination for msini. ~neptune. evidence for additional planets? collecting many previous spectra #tasc5
@ashleychontos <100 seismic hosts to 2016. Rereduce data, some new hosts, old hosts missing? KOI-4 Kepler's first planet actually around a subgiant. Find new seismic stars w/ planets near radius gap. K2 systems with seismo- small spacing gives age. Tess sesimic hosts too. #tasc5
@ashleychontos pushing hard to get asteroseismic parameters for exoplanet host stars, including using old-school things like pen, paper, and Tim Bedding: #tasc5
T. Campante do seismo of known hosts. 1 sector, see oscillations. Estimate dPi, see rotation doublets- edge on? Better star&planet mass. Evolutionary state- maybe clump? Hard to explain planet in that case. Compare K2 vs Tess~.75 different, consistent with bandpass. #Tasc5
.@vaneylenv encourages a large group of asteroseismologists that planets are cool too by showing it’s easy to find a diversity of planets. In fact, apparently we don’t even need scientists anymore... just Twitter bots. #TASC5
.@vaneylenv On Asteroseismology with Planet Hosts. He is pleased to introduce us to @I_Find_Planets , suggesting that we all will enjoy finding planets #tasc5
A. Noll size of convective core is uncertain. Want to calibrate with subgiant. Look at g dominated versus p dominated, constrain structure. Evolve quickly- challenging to model, so pre-optimize. Best model alpha~0.15, exclude >0.2. Models sensitive to physics choices. #Tasc5
I. Colman 6791& 6819 targeted with superstamps. ~2000 untargeted members. Use image substraction, better than aperture for variability. Align images. Can be contaminated by nearby variability. See new oscillators,rotation, Binaries! ~400 variables. Good S/N. Next:K2 &tess #Tasc5
Pros: all preprocessed FFI data will be published
Cons(?): ain't no notebooks for this one, just good old shell scripts! #Tasc5
András Pál: today we have the capability to just download all TESS (and Gaia) data and run processing locally #Tasc5
@afeinstein20 software demo of eleanor- which does background subtraction and aperture photometry to construct light curves for full frame images. Give it coordinates or IDs can interact with Tess cut, working to add better psf modelling #Tasc5
