متن کاملDimming Titan Revealed by the Cassini Observations
Here we report the temporal variation of Titan's emitted energy with the Cassini/CIRS observations. In the northern hemisphere, the hemispheric-average emitted power decreased from 2007 to 2009 and increased from 2009 to 2012-13, which make the net change insignificant (0.1 ± 0.2%) during the period 2007-2013. The decrease from 2007 to 2009 is mainly due to the cooling around the stratospause, ...
متن کامل9 S ep 2 00 9 Titan ’ s Prolific Propane : The Cassini CIRS Perspective
Although propane gas (C3H8) was first detected in the stratosphere of Titan by the 14 Voyager IRIS infrared spectrometer in 1980, obtaining an accurate measurement of its 15 abundance has proved difficult. All existing measurements have been made by modeling 16 the ν26 band at 748 cm : however different analyzes over time have yielded quite different 17 results, and it also suffers from confusi...
متن کاملThe Titan 14N/15N and 12C/13C isotopic ratios in HCN from Cassini/CIRS
We report the detection of H13CN and HC15N in mid-infrared spectra recorded by the Composite Infrared Spectrometer (CIRS) aboard Cassini, along with the determination of the 12C/13C and 14N/15N isotopic ratios. We analyzed two sets of limb spectra recorded near 13–15◦ S (Tb flyby) and 83◦ N (T4 flyby) at 0.5 cm−1 resolution. The spectral range 1210–1310 cm−1 was used to retrieve the temperature...
متن کاملFluvial channels on Titan: Initial Cassini RADAR observations
Cassini radar images show a variety of fluvial channels on Titan’s surface, often several hundreds of kilometers in length. Some (predominantly at lowand mid-latitude) are radar-bright and braided, resembling desert washes where fines have been removed by energetic surface liquid flow, presumably from methane rainstorms. Others (predominantly at high latitudes) are radar-dark and meandering and...
