Un eshel, un Alpy600 et une Sardine au foyer d'un superbe télescope récemment mis en service sur le plateau de Calern. Nôtre première nuit a été gachée par des pluies diluviennes. Mais le ciel clair est ensuite vite revenu, nous observons des étoiles variables mal connues et des astéroides. A nous les découvertes grâce au télescope de 1m du C2PU !

First spectra of a supernova  in the galaxy PGC 006399 (ATel 6714) taken at C2PU with an Alpy600 low resolution spectroscope

Somes others results:

First specta ever of Dauban V250

A large h beta line for this unknown type variable. A relative featureless spectra for a probable fast rotator object.

DaubanV250_Hbeta

 

Spectra of HR326, A Be candidate

H alpha and H beta lines are fill in by a slight emission. No emission in HeI lines. Seems to be a good candidate.

HR326_Hbeta

 

HR326_Halpha

 

New phase of matter ejection of IU Aur, last seen was in December, 2013

V/R variations of HD39478, may indicate a multiple system

HD39478_Halpha

 

End of P cyg profile phase in h alpha of HD36112, a Herbig Be star with stron stellar wind

HD36112_Halpha

 

First spectra of JCT3, a recently visual double star discover at Observatoire de la côte d'azur with the Nice great 76cm refractor by Jean Claude Thorel with an angular separation of 0.3 arcsecond. A K type star.

Profile variation of HD38191, double peak in H alpha and H beta lines

Mission team at C2PU is composed by Pierre Dubreuil, Alain Lopez, Stephane Ubaud, Thibault De France and Thierry Garrel

More to come with Sardine, a new echelle spectroscope, Alpy 600 and even star analyzer on asteroids.
