(cba:news) Stars for August-September (Joe Patterson) [2016-08-24T21:59:16Z]



Dear CBAers,

It's time to pull the plug on a few stars. None have been overcome by onrushing twilight - the usual fate - but the coverage has been so good that the data excellently show the period structure and/or waveforms. These are V1494 Aql, FO Aqr, and V2069 Cyg. Done. A couple of runs in November on the latter two will secure the year-to-year cycle count beyond doubt... but lay off 'em for now.

ES Cet is a great target. Slightly off season... but with a rapid payoff, since we only need a few weeks' coverage to nail down the period change.

Three new northern stars which I recommend are these:

V704 Andromedae. An old friend which we never published... and needing more observation. Preferably a lot more - worth making friends with.

V1500 Cyg. 18th magnitude but with a 1 mag modulation.

LS Peg and LQ Peg. There are published claims which conflict with our previous study, and with each other Let's find who, if anyone, was right. Nice bright stars, usually; definitely need long runs. I'd rate LQ Peg higher priority, but it's just a guess which will be more productive

Enrique will advise on J2133+51 and KIC 9406652. These results are great, but he'll decide when we have enough.

In the south, V4743 Sgr is currently my favorite, followed by the two Menfolk (AQ and AH; I think AQ is probably the better choice)

But AO Psc and V380 Oph are good targets for all hemispheres!

P.S. still meditating on HR Del...
