Interesting report - http://www.physorg.com/news/2011-02-...ark-stars.html

There must be so much un-seen heavy matter out in space it is hard to think it is all dark matter.

Just started a new thread on this one ..

Star formation.

Time to give the ol' "Trillions " thread a well-earned rest, eh ?

Cheers

The other thread is based on Star formation, my reason which this thread talks allot about is Dark Matter. Maybe you are right, I will consider opening a new thread later as I have to get to work cleaning things up before starting Uni.

You've finished it?! And I was just about to make a comment on how this surely must be the highest posted/viewed thread in the "Serious Astro Businesss" dept, uhm meant Science Forum.

Can't believe how long this thread ran for.

I see I have some reading on this thread to catch up on.

Hello Craig & Carl & Stephen

I haven't visited this section for a while as I have been busy memorising star names

. Why oh why does each star have two names.

My brain was getting too congested learning astro physics at the same time.

. Looking forward to catching up on some reading here again. Keep up the good work

.

Most stars have far many more names than just two

Please don't confuse me further ...

for I am just a weak, struggling, apperture challenged, overly light polluted, beginner.

Are you talking about the numbering system, Carl? I don't need to know that (do I

), but you do

For now I'll stay happy knowing for example that Avior is also called Epsilon Carinae.

Sorry Mr Moderators, back on topic.

renormalised (Carl) · #**130** 26-02-2011, 10:41 PM

Avior = Epsilon Carinae = HR 3307, CD−59°1032, HD 71129, SAO 235932, FK5 315, HIP 41037, GC 11463, CCDM J08225-5931

( And, does it have a planet/s orbiting in the system??....haven't a clue and probably not

)

Hi Suzy.

My name is spelt Steven.
That's OK however as I have been called a lot worse with very different spelling.

Back to topic.

Regards

Steven

but my typing fingers had other ideas.

Apologies Steven and thanks for bringing it to my attention.

I hate it when I say Suzanne and people say Susan back to me.

The one problem with red dwarfs is that for a planet to get enough warmth it needs to nuzzle in real close. But that puts the planet at the mercy of the star's gravitational tidal effects, effectively slowing or stopping the planet's rotation relative to its sun.

With one face always to its sun, a planet like Earth would likely develop life only in the twilight zone near the terminator or sunset line. It's doubtful that such planets would yield intelligent life and civilizations.

The one big exception to this would involve twin planets where both worlds force a rotation relative to their sun. They may not get tired of each other's face, and that helps to spread the heat around, making them indeed more Earth-like. Of course, such twin-Earths are likely to be extremely rare -- the right size and the right distance from their parent star.

Hi Steven
The spelling of "stephen" as a proper name is often a cause of error. The name has many variations in most languages.

When I was young the standard was that if it was a christian name it was spelled Stephen and if it was used in a surname it was spelled Steven. However as it is used as a proper name always to my knowledge the spelling is entirely at the perogative of the "owner"

So Hi Steven

Barry
