Dear all,
The NASA space photometric mission TESS is observing all types of stars
in the sky, including Be stars. This is a good opportunity to perform
combined spectroscopic and photometric studies, which would help to
understand Be outbursts. TESS changes field of view (called sectors)
every 27 days, therefore we need to concentrate on Be stars that have
rapid outbursts.
Jonathan Labadie-Bartz has put a list of interesting TESS Be targets
together, which is available here:

The following link tells you which sector TESS is observing at what time
(currently sector 15): https://tess.mit.edu/observations/#sched
It would be great if we could obtain 1 spectrum per night of each Be
target being observed by TESS (during the TESS observations). This means
we would observe the Be targets of one sector for 27 days, then move on
to the targets of the next sector for 27 days, and so on. Ideally what
we need is high-resolution spectra, at least Halpha and if possible full
echelle spectra, but lower resolution spectra are welcome too.
If you wish to participate to this project and you obtain data of the
TESS Be stars, please upload them in BeSS as usual.
Thanks!
Coralie Neiner
