iPod iChing: exoplanets or black holes

By catdynamics on February 4, 2011.

while I contemplate 1200 candidate planetary systems, and a hundred black hole researchers, I turn to the Mighty iPod

ok, so I got no blogging on the new stuff or the backlog done this week

Oh, Mighty iPod One: exoplanets or black holes?

Whoosh goes the randomizer.
Whoosh.

Well, we got no choice... that's the summer out.
Root is perspicacious... Rock Steady, eh?

The Future: Yule, Yule (Yule Is Coming Soon)!

The Inside: a little boy wants to collar a puppy, in exchange he'll share his cake, when he gets it (at christmas)...

The Outcome, after all that, is ambivalent.
Monophony and Polyphony alternate.

As always, the Key as explained by Sean

We expect to see white dwarf transits, or eclipses technically.
There are papers by Farmer & Agol and diStefano et al, as I recall, on rates and light curve properties, and two of the early announcements were the low mass He-WDs eclipses, the ones that looked like "super-hot Jupiters".
Regular C/O core white dwarfs have ten times smaller radii and will tend to be bluer, but they are there.

As I recall there are currently 3 published cases of transiting white dwarfs in the Kepler data. KOI-74b and KOI-81b were the first (and received some media attention as being planet-sized objects that are hotter than the host star), there is also another case KHWD3.

If kepler is designed to see earth-sized transits, then shouldn't it also be able to see C/O WD eclipses? I thought they were similar size.
