When asked about Charbonneau’s criticism, Barman cited similarities between Charbonneau’s landmark findings and his own. “David used the exact same method, exact same instrument, exact same telescope, the exact same planet, and the exact same uncertainty in measurements to discover the existence of extrasolar planets,” he said. [SEE CORRECTION BELOW...
...findings show strong evidence for water’s presence in HD209458b’s atmosphere,” Barman said. “Now that we know that water vapor exists in the atmosphere of one extrasolar planet, it’s probably safe to say that other extrasolar planets also contain water vapor...
...develop his models, Barman used a technique called transmission spectroscopy, which examines the light from a parent star as it passes through the outer reaches of a planet’s atmosphere. By analyzing the absorption patterns of the star’s light, he was able to deduce the molecules present in the planetary atmosphere...
Charbonneau was less optimistic, saying that Barman did not conclusively prove water’s existence in the atmosphere of HD209458b...
...said that regardless of any discrepancies, Barman’s paper will help advance astronomy by forcing a closer comparison between predictions of atmospheres on extrasolar planets with actual data gathered by observatories. CORRECTION: The April 13 news article "Water Found in Planet's Skies" incorrectly quoted astronomer Travis Barman. He said that Assistant Professor of Astronomy David Charbonneau had discovered an extrasolar planet's atmosphere, not that Charbonneau had discovered an extrasolar planet...
