Dear Campaign Participants,
a full 43 days period of the VV Cephei B-star axis precession is now observed.
The density of observations is unique in astronomy. Thank you very much for your effort and for supporting this campaign.
The newsletter shows the analysis of the first 43 day period
VV Cephei Newsletter 2024-10
We are completely in the expected phase which was calculated from the data of the last campaign.
Because of the high cadence of spectra we got a very precise picture of this period of precession.
Please stay tuned so that we can measure the next periods just as precisely.
Best regards,
Manfred
