The Q2 Kepler data has been officially released, making at least another 90 days of data available! Now the planethunting community should be able to confirm or deny their discoveries more easily!
Quick summary of the news in case you missed it:
The Kepler team have also released a scientific paper on the new planet candidates for anyone interested in the details (including lots of nice graphs showing the planet distributions too!).
Most of the paper is made up of tables showing the stars and planets, but that’s rather hard to search through or do anything with… so I spent this morning turning that into an Excel spreadsheet! You can download this from the link below – the spreadsheet contains both Table 1 (star list) and Table 2 (planet list) from the paper. I also added the Kepler IDs for the stars from Table 1 to the planet list (these aren’t on the original Table 2), which makes it much more useful for planethunters wanting to track down specific systems!
The spreadsheet itself has four sheets in it – the first is the planet list, the second is the key to the planet list, the third is the star list, and the fourth is the key to the star list (I put the keys on separate pages so that they don’t get in the way of the data if you want to sort that).
If you don’t have Excel, here is the Full planet list in .csv format, and the full star list in .csv format (note that these don’t include the keys – you’ll have to get those from the paper or the excel file). Right-click and select “Save As…” to save the files!
EDIT (12th Feb ’11): I’ve added the Stellar Luminosity, as derived from the star’s Radius and Teff (using L=4.pi.R².sigma.T4) to the Star List sheet in the excel and csv files. Since this is a derived value, it’s only as accurate as the Radius and Teff. I’ve also added the Absolute (visual) Magnitude and the Distance to the star in lightyears (see key for details).
Among the interesting things revealed by the table:
There’s lots more interesting stuff to look at in there! Stay tuned for more – in my next blog post (which I’ll put up in the next couple of days), I’ll be describing how to extract the Q2 data from the FITS files from the MAST site.
