An upper limit for the water outgassing rate of the main-belt comet 176P/LINEAR observed with Herschel/HIFI
M. de Val-Borro, L. Rezac, P. Hartogh +15
176P/LINEAR is a member of the new cometary class known as main-belt comets (MBCs). It displayed cometary activity shortly during its 2005 perihelion passage that may be driven by…
First results on Martian carbon monoxide from Herschel/HIFI observations
P. Hartogh, M. I. Błęcka, C. Jarchow +48
We report on the initial analysis of Herschel/HIFI carbon monoxide (CO) observations of the Martian atmosphere performed between 11 and 16 April 2010. We selected the (7-6) rotatio…
Herschel/HIFI observations of Mars: first detection of O_2 at submillimetre wavelengths and upper limits on HCl and H_2O_2
P. Hartogh, C. Jarchow, E. Lellouch +47
We report on an initial analysis of Herschel/HIFI observations of hydrogen chloride (HCl), hydrogen peroxide (H_2O_2), and molecular oxygen (O_2) in the Martian atmosphere performe…
HIFI Observations of Water in the Atmosphere of Comet C/2008 Q3 (Garradd)
P. Hartogh, J. Crovisier, M. de Val-Borro +42
High-resolution far-infrared and sub-millimetre spectroscopy of water lines is an important tool to understand the physical and chemical properties of cometary atmospheres. We pres…
A study of the distant activity of comet C/2006 W3 (Christensen) using Herschel and ground-based radio telescopes
D. Bockelée-Morvan, P. Hartogh, J. Crovisier +35
Comet C/2006 W3 (Christensen) was observed in November 2009 at 3.3 AU from the Sun with Herschel. The PACS instrument acquired images of the dust coma in 70- and 160-micrometers fi…
