Hello all ... Just 2 questions : 1st I use the comparizons æ & ç for the ccd imaging at 3.231 & 3.740 magnitudes... Are those numbers still valid ??? (one of...
Hello JD, Zeta Aurigae is an eclipsing binary system, but it is not in eclipse now and will not be for a couple more years. It is safe to us it. Last night I...

All - I did some Eps Aur photometry on April 1-2, 2010 and I came up with an average +3.74 V magnitude. I think the brightness is holding it off. Jeff - I...

Hi Jeff, Here you'll find last spectra i've done after the last i sent to you on Jan,15th. There is none in February cause of the weather and holidays. I'm ...
Thanks Thierry, I will add these to the table and we can add any missing information later. Is there anyone else with spectra which are not already included...

Hi all, Ha Ew, taken between 6559A and 6567A seems to climb at an increasing rate as the R emission part disappeared from the spectrum. First part of the EW ...
Hi Thierry, Your Ha results, particularly when combined with other recent data for example from Christian and Benji and the historical data from Lothar, Jeff...

Very interesting, need to think about that. I've just finished a compilation of all my spectra. They are not normalized, the continuum is preserved (and...

Some comments and questions I think we should tread carefully here regarding contact points. Contact points have been determined in the past via photometry. I ...
Hi Jeff, Yep. This system is causing us to rethink our definitions yet again as we we have recently had to do over "primary" and "secondary" Photometry does...
Hi Robin, I think the solar and planetary contact points fall in line with the interferometric images as they are images. Normally for stellar contact points...

All - I agree with everybody here. Between interferometry and photometry, I believe the resolution may play a big role here. Also, don't forget about the...

Hi Thierry, Thanks for the full set of spectra. I will update all your entries on the list. Here is a paper which shows how the Ha and Na D lines developed...
