Hi,

Following the 2018 3 days of "rencontres du ciel et de l'espace", here is the link to my presentation on "ISIS & Visual Spec from preprocessing to results". It is in French.

A new version of Visual Spec is now available. Main effort was put on the installation, less dll missing messages shall appear… In addition, the version includes few new features. • Scaling on all series • Local continuum rectification • One, two, three gaussians fit • Wavelets • EW time series • Ba...

Albert To check calibration do not use the star line, as mentionned above the h-alpha has lot of reasons to not be at exact laboratory wavelength: heliocentric earth motion, doppler... The best is to use the earth atmosphere telluric lines. You can superimpose them with ISIS, VSpec... it is the easi...

Real time detection of V532 Lyr on the OHP field - spectral type B4Ve - on the 28th of July V532Lyr.JPG And after processing _v532lyr_outburst2017.png This is not the first outburst recorded in BeSS - see the time serie V532 Lyr time serie.png The semi quiet period lasted about 7 months. The stronge...

Hi I put online today a beta test new deloyment of Vspec which shall be more friendly with W10 et.al. As it is always challenging to test on different windows plateforme I kept on line the previous distribution and the capability to upgrade to the version 4.3.2 from your current installation. No big...

Salut Olivier

Yes cx dra is a star which has a profile which evolves quite often. In fact it is a Binary star B3+F5III
Here is the summary view for all the BeSS spectra - evolutions from day to day can be observed. Would worth a look at litterature.

Hi Tim
Interesting outburst captured. And your spectrum is validated in BeSS. Will be available within a day.

Valerie

For your future observations, I would suggest to add few Be Stars on your list. In addition to gam cas, pi aqr, Pleione, we have a professional request for 28 CMa spectra and if some of you can take some spectra of 12 Aur and V584 Per that would be great to confirm recent BeSS submissions. Thanks Va...

We have a request for observations of the Be Star ome CMa Dear Valierie, My name is Alex Carciofi, I’m a colleague of Thomas Rivinius working on Be stars. In particular, I’m studying (with several other collaborators) the Be star 28 CMa. We have reasons to believe that the star should start a new ou...

Hi
I do not know about Rspec.
For ISIS, you have to dowload the file, unzip it, then you need to change the extension .FITS into .FIT - That's the trick...
For Visual Spec, you can download the zip file and drag and drop the zip directly on the yellow space of Vspec.
Cheers
Valerie
