No Detection of a Scar on Jupiter in the NIR

[ 3 ] Comments

Some news about the Jupiter flash which was detected on September 10. I reported the absence of detection in the visible light from data collected by amateur astronomers. Glenn Orton, a  colleague from the Jet Propulsion Laboratory,  sent me yesterday two observations of Jupiter taking with the IRTF telescope and the SpeX Guiding camera in the near-infrared. No scar, or debris field, can be seen at the location of the flash. The meteoroid did not enter in the inner part of the planet atmosphere. This observation confirms that it was most likely a meteor.

About Franck Marchis

Dr. Franck Marchis is a Senior Researcher and Chair of the Exoplanet Group at the Carl Sagan Center of the SETI Institute since July 2007. Over the past 19 years, he has dedicated his research to the study of our solar system, specifically the search for asteroids with moons, using mainly ground-based telescopes equipped with adaptive optics. More recently, he has been also involved in the definition of new generation of AOs for 8 -10 m class telescopes and future Extremely Large Telescopes. He has developed algorithms to process and enhance the quality of images, both astronomical and biological. His currently involved in the Gemini Planet Imager Exoplanet Survey, which consists in imaging exoplanets using an extreme AO system for the Gemini South telescope. This new instrument is capable of imaging and recording spectra of young Jupiter-like exoplanets orbiting around nearby stars.

    J’ai lu rapidement dans le “Ciel et Espace” de septembre un article qui mentionnait le lancement d’un téléscope spatial en IR pour surveiller les météorites. Il est appelé “sentinelle de la Terre”. Ce serait en 2017, le mâitre d’ouvrage étant la fondation américaine à fonds privés B612. C’est vrai ?
