Anatoly Miroshnichenko delta Sco talk at Brasil ESO2012

[Thierry Garrel]

Hello
here is the presentation that Anatoly gave at ESO 2012 conference on hot stars in Brazil.
Some comments of the author:
"The ESO conference was quite intense in communication. There are lots
of data obtained for Delta Sco during 2010/11. My presentation was
received very well with about the largest number of questions. I'm
attaching a PDF version of my presentation. As the radial velocities
are re-checked, I will be contacting everybody about the regular
paper."
Final paper is ongoing. Del sco campaign has revealed the potential of amateur spectroscopy for the professional world.

Salut,
voici la communication d'Anatoly à la conférence de Février 2012 de l'ESO sur les étoiles chaudes au Brésil.
Commentaires de l'auteur:
"La conférence ESO était tout à fait intense dans la communication. Il y a des tas de données obtenues sur Delta Sco pendant 2010/11. Ma présentation a été très bien reçue avec le plus grand nombre de questions. J'attache une version PDF de ma présentation. Comme les vitesses radiales sont re-vérifiées, j'entrerai en contact avec chacun pour le papier final"
Le papier final est attendu. La campagne del Sco a révélé le potentiel de la spectroscopie amateur pour le monde professionnel.

As Anatoly wrote me, the "third body" theory is further an option (first time mentioned of my friend Thom Gandet in September 2011, when we saw the "double dip" in Halpha-RV). This seems obviously to be a outcome of the expert discussion in Brazil.

Before this background, here the newest state of the star in EW and RV (see attachment).
In order to check the reliability of the RV measurements without mirrored technic, I have re-evaluated with the mirrored method within the "RV-cloud" after the periastron some spectra of J. Guarro and B. Heathcote (blue diamonds). It seems, the application of this method leads to some lower values.
