Hi all!

Here is a project Tony Moffat (Montréal) put together that might be of special interest for you. Currently BRITE is observing the famous O-type short-period binary UW CMa, in case you are interested. Updating of the wiki which gives what’s being and will be observed is in progress.

Cheers, Thomas

Hi Thom:

Thanks for posting this! I already have SASER involved. And for 6 weeks I
had a visitor (Jamammad Rustamov) from Azarbaijan here to negotiate joint
observations using their 2m Zeiss telescope near Baku for spectroscopy.

Happy Christmas and Merry New Year!

Thon

Hi Thomas!

I'm interested to work on this exciting project!

greetings
Siegfried

Hi Thomas,

 

As you know, the southern hemisphere SASER group is also working on this
project and I am wondering if there is a way we can coordinate/communicate with
any northern hemisphere amateurs who plan to participate, especially if we
happen to pick some stars visible to both north and south. What do you
think?

 

Cheers, Bernard

SASER (Australia)

Hi,

the Position of the mentioned star is to near the horizont for me (my position is nearly N50°!) But what is with the other stars in the list attached?

I asked Prof. Moffat what format of spectra he whish........raw spectra or reduced one. But at time I have no answer......

Do you know this
cheers

Hi all:

Sorry to be slow in answering, Berthold. The idea is for you to choose your
own targets based on a 2-step process:

1. From the list I circulated of windy massive (hot) stars, then among
those:

2. From the list of stars currently being observed by BRITE, as indicated on
the BRITE wiki: http://brite.craq-astro.ca/doku.php .

Currently BRITE is observing the CMaPup field (click on it and you'll see
the list of stars oops, sorry they're not up yet for some reason - I'll get
after this; but I do know that the O+O binary UW CMa is being observed).
The next field is CruCar (the targets are listed now). And so on...

Hope this helps. Now go for it! Your help in this will be much appreciated.
These are all very bright stars, so fairly easy to get frequent high-quality
spectra.

Best regards,

Tony

Hi Bernard! Because the SASER team is hidden in the Web it would be best to announce the procedure how to become a list member so that everybody in the north is informed and can join SASER. The other possibility would be that SASER goes VdS forum. I am in both groups, so I do not mind. I presume the former is the better way to go because SASER is homogeneous, reliable and highly organized. In contrast to the south there is no real team organizer in the north.

Cheers, Thomas

Hi Thomas,

 

As you well know SASER is just a small southern email ring designed to
allow campaign specific coordination between amateurs and pros and not a general
discussion forum. As SASER membership is limited to amateurs willing and able to
contribute spectra I think the best way to collaborate with a northern BRITE
contributor is for that person to contact me via this forum and I can then add
them to the SASER list.

 

Cheers,

Bernard

That is exactly what I mean, Bernard! SASER is exclusively for the observers and should continue like that. Cheers, Thomas

Hi again:

The currently observed field with BRITE, CMa/Pup, is now on the wiki so you
can choose your stars as of point 2. below.

Cheers, Tony

Hallo,

im Rahmen der Kampagne untersuche ich auch eps persei. Ich will hier nicht in Einzelheiten gehen, aber es ist schon beeindruckend, wie sich in sehr kurzer Zeit Linienprofilveränderungen zeigen, z.B. schon nach 15 Minuten im Bereich der Linie 6678 oder auch an den SiIII Linien........das S/N liegt nach 3x300 sec über 300.....naja, gut der Stern ist recht hell und steht hoch am Firmament.


berthold

Hello Berthold:

Which campaign are you referring to? BRITE is not observing the Perseus
filed now; it was already done in 2014/15. eps Per will, however, be
observed again by BRITE starting next September. The PI for this star is
Gerald Handler, now in Warsaw.

Beste Gruesse,

Tony

Hi Tony,

perhaps I confused something. Prof. Gerald Handler is now inetrested at this time on those spectra of this star. He asked me to create some spectra.

herzlicher Gruss
