Et quelques grandes classiques intéressantes :
- delta Sco [7 days] : continuous monitoring is key, specially as it approached periastron (Feb-May 2011) ; seem its disk recently evolved toward a ring... very interesting star to follow.
- gamma Cas [180 days] is still interesting to get spectra from time to time ; EW is evolving
- 48 Lib [90 days] : very interesting, V/R ratio is growing since few years ; to monitor
- bet CMi [60 days] : late Be star, symetrical V/R but radial velocity to monitor. 700 days period ? Need more data there to constraint a period...
- phi Per [90 days] : EW changed, down from 48 to now around 36-38. Bright Be binary candidates to monitor ?
- 66 Oph [180 days] : double peak spectrum, more southern but interesting to look at. Peak separation changed between the 1990’s and now. Is disk dissipating ?
- omi Cas [180 days] : no emission lines in 1970’s ; Intensity around 4 in 1990’s and now around 6. Is the emission single-peak or triple ? Concentration of material in a Roche lob with presence of a companion ? EW is now reaching 40A (was 20 in the 1990’s !).
- pi Aqr [60 days] : single peak in 1982, double peak after, then in 1996 absorption line with a single line swinging with a period of 84 days. It is worth to continuous monitor this star now.
- ups Sgr [90 days] : was the subject of study of a pro ; interesting Be star spectrum merged with a later type star, lot of absorption lines in the spectrum.
- EW Lac : [90 days] bright Be binary candidates to monitor (EW : 46
- V777 Cas [90 days] : bright Be binary candidates to monitor (EW : 20-45)
- V695 Mon [90 days] : bright Be binary candidates to monitor (EW : 45)
- HD206773 [90 days] : bright Be binary candidates to monitor (EW : 0-43)
- 105 Tau [90 days] : bright Be binary candidates to monitor (EW : 42)
- HD208682 [90 days] : bright Be binary candidates to monitor (EW : 41)
- HD202904 [90 days] : bright Be binary candidates to monitor
- DX Eri [90 days] : bright Be binary candidates to monitor
