My short contribution for the proceedings of the IAU Symposium 357 detailing the research project that I'm undertaking for my NSF Fellowship is on
@arxiv. "The Search for Planet and Planetesimal Transits of White Dwarfs with the Zwicky Transient Facility" https://arxiv.org/abs/1911.07889Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
If it's too late to adjust the extended mission cadence, I hope that future extensions will adopt different cadences that aim specifically to break these solution degeneracies caused by Nyquist aliasing! [5/5]

I would love to hear what the TESS community thinks! I hear that having the new cadence be exactly 1/3 of the original cadence helps exoplanet science. I think phase sampling would improve with the suggested cadence change to improve transit profile and timing measurements. [4/5]

With the 10-min cadence as planned, frequency solutions for TESS observations of many variable stars will be ambiguous, putting a strain on follow-up observing facilities and limiting some science results to those researchers with abundant telescope access. [3/5]

This figure shows how Nyquist aliases appear at the same locations for both 30- and 10-min cadences since one is a precise multiple of the other, yet a different (e.g., 11-min) cadence could eliminate all Nyquist ambiguities across the combined TESS data set. [2/5]pic.twitter.com/sHRDSnQ9nF

Check out my new
@AAS_ResNotes "TESS Extended Mission 10-Minute Cadence Retains Nyquist Aliases" (esp.@TESShelp,@TESSatMIT,@NASA_TESS ppl) to see how a tiny adjustment of the extended mission cadence could greatly improve the impact of the data.

Glad that, despite their name,
@NASAExoplanets is sharing stellar astrophysics results, including the write up about this very interesting cataclysmic variable system.https://twitter.com/NASAExoplanets/status/1224747150698926080 …

The ELM Survey found and characterized such an interesting population of extremely low-mass white dwarfs that formed through binary mass transfer. It has been the starting point for much of my work. Congrats on the 8th and final paper!https://twitter.com/arXiver/status/1224534155800694785 …

Any undergrads want a paid summer internship at
@NASAGoddard? Our group is looking for 5 awesome people to help us find and study planets with TESS. I can nearly guarantee you'll discover a new exoplanet if you want to work on the search side!

Howe et al. "The uncovered shift... of ~25 µHz, translates to an uncertainty of 0.8 per cent in radius and 2.4 per cent in mass... results flag the need for caution when using ν_max in asteroseismology." Very useful work, helps quantify extrinsic measurement uncertainties!https://twitter.com/arXiver/status/1222716528878964737 …
