Link Roundup

I'll admit, this may have less actual content than some of the previous entries in this blog. Think of this, maybe, as a snapshot of the last three years:

From the National Geographic News, coverage of the second "puffy planet" HATnet discovered. There's nothing here that hasn't been said before, but it does quote Bakos, and the quotes are fairly interesting.

Via the Space Telescope Science Institute, it's possible to look up in their archives when in the past Bakos has given talks for various colloquia and symposiums. They have from the previous spring's colloquia certain talks archived as videos, and Bakos' is among them.

Finally, there is another article relating to this year's discovery, through Astronomy Now. What is truly of interest, though, is at the end of the article. A new space telescope, the Kepler, is to be launched next week; its purpose is to search for extrasolar planets, particularly of Earth-like nature. One of the planets it will scrutinize will be this new discovery by HATnet, according to the article. From space, so the hope is, it will be possible to resolve more information than the currently ground-based telescope system that makes up HATnet.

Another discovery

I'm not sure exactly how I missed this piece of news (in fact, I only found it by checking Harvard's news releases), but almost a month ago it seems that the HATnet team announced the discovery of another large exoplanet, HAT-P-11 b. It is apparently another large gas giant similar to their first discovery.

There's an interesting simulation of the planet orbiting its star here. As one can see, it possesses a rather eccentric orbit.

It would appear that large planets are much easier to discover, when HATnet's success is compared with other teams. Perhaps larger objects are more likely to cause a noticeable distortion (the wobble) to the star they orbit; this would fall in line with what physics would predict.
