COROT

[alokmohan]

The space-borne telescope, COROT (Convection, Rotation and planetary Transits), has just completed its first year in orbit. The observatory has brought in surprises after over 300 days of scientific observations. <br /><br />Pioneering precision measurement over long periods of time COROT is observing a large number of stars, up to 12 000, simultaneously, at a very high precision - unprecedented in ground-based astronomy. The key to the high-precision is that the observations can be carried out over very long periods of time - up to 150 days. This is being done for the first time ever. <br /><br />The satellite measures variations in the light output of these stars down to one part in a million. This level of precision allows scientists to study the many ways in which stars vary. The pulsations are caused either due to unknown physical processes in the stellar interior, or by objects such as planets passing in front of the stellar surface. <br /><br />A treasure trove of information for stellar seismology <br /><br />To date, 30 stars have been observed as part of the study of stellar seismology, the study of the miniscule changes in light output from a star caused by acoustic waves travelling through the star. The pattern of the changes tells us a lot about what is happening deep inside the star. The stars observed by COROT range from objects similar to our own Sun to older or more massive stars. The observation period varies between 20 and 150 days of essentially uninterrupted study. <br /><br />After a preliminary analysis, the measurements have revealed very exciting results Research into solar-type oscillations is one of the mission's key objectives. Such oscillations have already been <br />

Yes, it his his job (and duty, by the TOS) that he provide it with his excerpt.<br /><br />This is mysterious, though :"On 10 December 2007, the first set of data obtained by COROT was released to the Co-Investigators of the mission. These scientists hail from the member states of the COROT consortium (ESA, Austria, Belgium, Brazil, Germany, and Spain)."<br /><br />So they held all the data for nearly a year, THEN released it to the co-investigators? My oh my, ESA sure does things different than NASA, eh?<br /><br />I can't wait till the data hits a journal so we can look at it in detail, rather than this synopsis.<br /><br />Thanx<br /><br />Wayne <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Apparently in addition to 2nd finding exoplanet COROT-exo-2b, several other exoplanets candidates are being analyzed for confirmation by on-ground observations.<br />

Being european I'm quite dissapointed by the ESA style of releasing news. Specially when it's in the style of "the latest news are that soon there will be news". It's like receiving reports on horse mail from Siberia on the XIX century.<br /><br />I'm sure there is more that could be said about the work of the COROT team during the last months, even if they don't want to release more science data. <div class="Discussion_UserSignature"> </div>

But we are expecting science data.More details of exoplanets.

ESA is poor inlatest news.But why?
