متن کاملObserving Titan with amateur equipment
We survey the observations of Titan that can be made using equipment available to amateur astronomers. Off-the-shelf hardware includes spectrometers and photometers that can detect Titan’s infrared light curve and potentially its clouds. CCD spectra and photometry (both photoelectric and CCD), even with small (20cm) telescopes, are useful for monitoring seasonal changes in Titan’s haze. Recent ...

متن کاملThe Selection of Tenured Astronomers in France
The organization of the recruitment of tenured astronomers and astrophysicists in France is presented and compared with the setup in other countries. The ages for getting tenure have increased from 27-28 in 1980 to 31 today. Foreign scientists constitute at least 11% of the recruits and the delay in their hiring is quantified. The large reliance on national tenure committees is justified, while...
