VV Cep and some Be stars with DADOS-1200

Postby Francisco Campos » Mon Jun 19, 2017 6:55 pm

Hello,

here are some spectra of Be stars (already at the BeSS database, except VV Cep) taken with the DADOS and the 1200 l/mm. This night the spectrograph performed particularly well. The resolution from night to night is quite variable (why?) but this night it reached R=7000. It depends of focusing, I believe. A very small variation, and the resolution can reach 7000 or be lower than 5000.

Hi Fran,
would you be so friendly to send me your spectrum of VV Vep and delta Sco?
