Hei,
Kaksi uutta havaittavissa olevaa eksoplaneettaa:
WASP-1 = GSC 2265-0107, V=11.5, parhaaseen katseluaikaan

Hello Everyone,
Today's astro-ph mailing has a paper by Collier Cameron et al. entitled
"WASP-1b and WASP-2b:
Two new transiting exoplanets detected with SuperWASP and SOPHIE",
describing the discovery
of P=2.15 d and P=2.52 d planets transiting ~12th magnitude stars.
The J2000 stellar coordinates are:
WASP-1 J002040.07+315923.7
WASP-2 J203054.12+062546.4
Dave Charbonneau at CfA writes:
"Great chance to catch WASP-1 tonight from the western US. We will
pursue it from Mt. Hopkins and Palomar, but
thought you might want to give a heads up to transitsearch.org. This
one is very much in need of a great light curve,
as the current estimates of Rp range from "smallish" to "huge", with an
error bar that is depressingly large."
And he's right about all that. Multiple data sets will be of great use
in constraining the system parameters. We'd really like to know how
these two new planets fit into the overall trends that are starting to
emerge among the aggregate of transiting planets.
The paper is at:
http://arxiv.org/abs/astro-ph?papernum=0609688
I'll be posting more on oklo later today. Both stars have been added to
the transitsearch.org candidates table.
with best regards,
