Re: Call for monitoring Be stars in the TESS sectors
Posted: Mon Nov 11, 2019 9:09 pm
Hi all,
I should have mentioned this sooner, but the spreadsheet (https://docs.google.com/spreadsheets/d/ ... sp=sharing) has been updated with regards to stars being observed in this current, and also the next, TESS sector. In particular I am focusing on two targets right now: V801_cas and CT_cam. Like before, I am trying to get as many NRES spectra as possible for these two right now. Over the next few nights I hope to have enough data that I can choose to focus on just one of these (probably V801 Cas, since it is brighter and more active; but CT Cam is just as interesting). Any spectra of these two stars in particular will be greatly appreciated.
Here is an incomplete and short list of some of the highest priority targets right now:
# ID, Tess_mag, Spectral_type, RA, DEC
CT_Cam 7.05 B2Vne 54.5043 55.17084
V801_Cas 6.08 B1Ve 47.22574 62.38456
CR_Cam 7.47 B2Ve 52.16344 62.49296
V818_Cas 7.77 B2Vne 357.47124 62.21413
BD+61_39 8.585 B0.5IV 5.072612 62.463852
V780_Cas 7.64 B1Vpe 30.65169 59.68809
BD+56_534 8.93 B2IIIe 34.86046 57.0784
HD_237056 8.04 B0.5Vpe 45.65787 57.61279
BD+45_681 7.886 B5V 44.314165 46.019957
All of the observations so far, especially for V357 Lac, look great (and obviously V442 And). Soon I will work on combining the many NRES + BeSS spectra for this star in anticipation of the TESS data becoming available (rough estimate of 1 - 1.5 months).
