[vsnet-chat 3666] RE: re HD 95687 in Tycho

[Sebastián Otero <varsao@fullzero.com.ar>]

So the range is confirmed: at B-V= 2.1, Vt is 0.24 mag. away from V, so the light curve shows a range between 6.9 and 7.5, in good agreement with my visual observations and PEP(V) from the ground.

I'm still wondering about the 2.91 day (???) period...

Looking at the light curve there seems to be a longer cycle superimpossed so the amplitude is probably larger.

A good one for us!!!!

 

Thanks, John as usual...

 

Best wishes,

Sebastian.

 

 

 

Attached is a 1.6kb giffed plot of HD 95687 Tycho VT photometry from epoch
photometry annex A where stuff with backgrounds over 16 has been slung, and
the rest unceremoniously forced into daily means.  Y axis VT, X axis M(B)JD.

Nicely sliced Sebastian.

Cheers
