Still catching up on the Extreme Solar Systems conference...
Lots of interesting stuff on planetary atmospherics.
Models are currently mainly looking at mean temperatures (at the 5-10% level) and horizontal global heat transport. Clear need to incorporate vertical transport and chemistry.…
Did I mention that I have been here a week and not got to the beach yet...
One of the penalties of being an organiser. Of course I slept that one free afternoon, but that was after trying to find the Olympic Airways office for 3 hours - they shut it, apparently people kept bothering them or…
Still at the Extreme Solar Systems conference in Santorini where it has cooled off a bit.
One of the locals assures me this is the worst since the great heat wave of 1916 and that I should come back in october... must make the most of this once-per-century opportunity.
So, more planet news...…
I'm still working my way through my notes from day 1 of the conference...
did I mention I have a lots of notes.
Actually, by my count, half-way through day 3, I've seen four very interesting announcements that are embargoed, two because of Nature/Science submission issues, which I will of course…
More planet news from the Extreme Solar Systems conference
In addition to the Jupier like planet (did I mention that I like that result...?)
the California-Carnegie-AAT team has several more long period jovians, possibly with low eccentricity orbits.
Looking at known planet hosts, 179 stars, 25 are…
There have been several interesting items at the Extreme Solar Systems conference here in Santorini
I think the surprise announcement from the California exoplanets groups that they have a genuine Jupiter analog - a Jupiter mass planet in a long period, low eccentricity orbit, very similar to our…
Petros M. Nomikos conference center in Fira, Santorini is a very nice medium capacity facility (~ 200 for the main room, which we are filling)
Well worth a visit, if you're planning a small meeting.
I forgot to bring my camera, but MacPro has a small built in web-cam...
View to Firastefani west…
Iranian news agency is reporting that the Bushehr nuclear power station is going online in October 2007
That is interesting.
It means the reports earlier that the fuel was delivered quietly by the Russians was accurate and they must be loading the reactor starting right now, if they want to be…
the long rumoured planet candiate around a nearby white dwarf has finally been made public
Fergal Mullally (U Texas) announced that they have strong evidence for a 2+ Jupiter mass planet around the white dwarf GD66 - a pulsating moderate temperature hydrogen white dwarf that is about 50 pc away.…
The Extreme Solar System conference at Santorini is off with a bang!
Number of announcements already in the first session, I'll catch up on the highlights later, and just give the, in my opinion, most interesting.
The California-Carnegie-AAT group has a genuine extrasolar Jupiter analog!

Ok, Santorini has broadband and WiFi
We're on. I'll intermittently live blog the meeting as I can and if and when anything on particular interest comes up.
And we're off, on time...
ok, I confess, I am now lounging on a small mediterranean island
Santorini to be specific.
(I hope, since I am using the movable type "scheduling" function, and am confidentially anticipating all flights and connections flew and connected)
I am not just lounging by the pool, indeed I suspect…
So, it will be friday, and we will ask: oh mighty iPod One - will we have robust detection of candiates for genuinely habitable extrasolar planets around nearby main sequence stars by 2010?
And, if so, can you tell us more...
Whoosh goes the randomizer.
Whoosh.

The incoherent ponderer ponders the joys of doing physics as a professor at a research university...
but to offset his irrational exuberance, he points to the classic "two geeks" post by Steve Hsu
Ouch.
Read the comments.
The first one, on the analogy with art careers is a point frequently made,…
Russian Foreign Affairs Minister Sergei Lavrov
"We have recently discussed the question with the Foreign Minister of Iran. We have no misunderstanding regarding the execution of contractual obligations regarding the construction of the nuclear power plant in Bushehr. We agreed to continue the…
This would be funny, but...
Congress questions VP Office claim to not be an entity within the executive branch
"I question both the legality and wisdom of your actions. ... [I]t would appear particularly irresponsible to give an office with your history of security breaches an exemption from the…
Greg at systemic makes a bold, and probably accurate prediction
observational sensitivity is now reaching parameter spaces where we can detect genuinely nice habitable planets, and the odds are that we will in fact see some real soon now
For what it is worth, I think he is right.
We're not at the…
A Supreme Court Justice cites a television show in his deliberations on torture...?

When I were a lad, we would occasionally get dismissed from school, particularly in early spring, usually at noon.
These were known as "Sun"-days, and were those rare days on which the sun shone in a clear blue sky and the temperatures reached a balmy 10-15 C (50-60F you heathens).
This…
It is a lazy sunny friday, and we ask humbly, what excitement lies ahead, oh mighty iPod one?
Whoosh goes the randomizer.
Whoosh.

Note to self: when submitting NSF proposals through Fastlane -
if you do a last minute revision then run LaTeX twice before generating the new PDF file, or the bibtex cross-cites break... ugly.
Apparently the panel really hates that. Really, really hates that.
Never had such a unanimous referee…

House subcommittee on Science and Related Agencies has marked up its appropriations bill
Looking good...
They give NASA and extra $290 million, majority for Science.
Sounds like they also plan to put in the barriers between line item spending in NASA, to preclude some divisions (exploration)…
My earlier rumouring was false, I hear third hand that the NRC committee on Beyond Einstein has not consolidated their reporting and sent it to the NRC, they are having one more meeting right about nowish.
Interesting.
Still due to submit to NASA Sep 8th, with an announcement on Sep 9th from…
There is a claim that the Russians have delivered the fuel for Iran's Bushehr reactor.
The source is DEBKA, which is interesting in and of itself.
The story is quite detailed, both in timeline and claims of political motivation (Putin pissed off at Bush, natch), but DEBKA is not entirely reliable…
Stormy friday, which is weird, ought it not to be thursday...
We approach the mighty iPod and ask, oh Mighty iPod One: is there a characteristic accretion signature of late stages of binary supermassive black hole mergers?, and is it LISA relevant?

Good news is that the east coast Whole Foods are now carrying plain skyr
Aahhh.
This is the real stuff, not the oversweetened flavoured vanilla stuff they've been pushing.
The bad news is that I bought it all.
Really, I think I cleaned out all the Whole Foods north of NYC.
BwaHaHaHaha!
