Eta Carinae - Brightening??????

[Merlin66 (Ken)]

Glad to hear that!
I'm sure it will be spectacular when it "blows"; I have bets on with my wife that it will happen before they lower me into the ground (with my Genesis 4")
Which HeI line? What resolution is required?

Eta Carinae is an unstable star blowing out hot gases.
It is about 7500 light years away.
Its hydrogen fuel is running out and soon gravity will cause it self to collapse and blow apart in a gigantic explosion.
It is a supernova waiting to happen.
Nobody knows when it will blow up.it could happen now or in thousands of years.

Well, I figure I've got about twenty years left....so if I win my bet -it will blow some time before 2031 -March.

Hi,

First post here.

I have been stocking up on sunscreen so I can wear it at night. I figure there may be a big rush on when this star goes off...



But is there real evidence of Eta Carinae brightening?

Cheers,
Peter Mead

Hi Peter, welcome to IIS.

The answer you seek is on the first page of this thread.
One source of 'evidence' is here: http://etacar.fcaglp.unlp.edu.ar/

Go to here
http://www.aavso.org/data/lcg
Enter "eta car" as the star.
Put the start date as 1/1/1590 and leave the other fields blank. (yes this is the correct year )
The light curve for the last 400 years will be displayed.

I followed your instructions and I got nothing
could give us a screen shot as to what the display looks like before asking for plot?

Ron, right at the top there is a menu displaying different requests. Once you have filled in the box criteria, you can then select from that menu. For example I found "View AAVSO Observations" very informative for a more detailed report consisting of days and times of the visual mag. observations.
Don't type in Eta Carinae - I have done this in the past and has gotten me no where . Do as Terry said and type it as eta car.

Thanks for that very helpful link Terry. I never got too far with this site until now.
