WASP-12b in Aur - A doomed exoplanet

Dear group,

An opportunity last night to revisit WASP-12b in Auriga. This
exoplanet requires just over one day to completely orbit its host
star. Due to its close proximity, it is highly irradiated and is
characterized with one of the highest surface temperatures of any
exoplanet find so far (2500 degrees Kelvin).

It is estimated that within 10 million years, this exoplanet will have
been devoured by its host star.

For last night's result, please see http://www.perseus.gr/Astro-Photomet...2-20111203.htm
.. My conditions were the worse encountered so far this winter with
very high humidity, thin ground level fog and poor seeing. The
advanced phase of the moon also helped light up the sky and which was
magnified further by the fog.

An effort from earlier this year using a smaller aperture is available
at http://www.perseus.gr/Astro-Photomet...2-20110114.htm .

Anthony.

Interesting! But what sources/levels are represented by
Comp and Check?

Grow up !

"Q. What causes the seasons?

A. The seasonal variation of weather on the Earth is affected by many
things, but the principal factor is the tilt of the Earth's axis with
respect to its orbital plane.

You often hear (correctly) that the Earth's axis is tilted, at an
angle
of about 23.4 degrees. But--23.4 degrees from what? Up and down? Up
and down from what? Up and down from the ecliptic plane."

If you were any good you would have figured out that the polar
coordinates are about to turn to a maximum distance to the circle of
illumination in their roughly 10366 mile circle /cycle to the central
Sun.

Te seasons are caused by an interaction between daily and orbital
turning to the central Sun,two distinct daylight/darkness cycles with
one location on Earth always at daily noon or midnight and a separate
line where a location is at orbital noon/midnight.It is far more
interesting and appropriate for the 21st century and kids will love
it.

It requires two things - experimental analogies supported by planetary
comparisons and especially Uranus and perhaps a third thing - a
genuine astronomer.

Brian,

The purpose of the comparison vs check star is to ensure the
variability noted in the exoplanet host star is not due to the
comparison star. As indicated by the second graph (comparison vs
check), the comparison star is stable and, as such, the first graph
(host star vs comparison) indicates the intrinsic variable nature of
the host star and not due to the comparison star.

I hope I understood your question correctly and my reply above makes
sense.

Anthony.
