The Debris Disk of Solar Analogue Ceti: Herschel Observations and Dynamical Simulations of the Proposed Multiplanet System
S. M. Lawler, J. Di Francesco, G. M. Kennedy +16
Ceti is a nearby, mature G-type star very similar to our Sun, with a massive Kuiper Belt analogue (Greaves et al. 2004) and possible multiplanet system (Tuomi et al. 2013) that…
Herschel HIFI observations of ionised carbon in the β Pictoris debris disk
G. Cataldi, A. Brandeker, G. Olofsson +9
Context: The dusty debris disk around the 20 Myr old main-sequence A-star β Pictoris is known to contain gas. Evidence points towards a secondary origin of the gas as opposed…
Comet-like mineralogy of olivine crystals in an extrasolar proto-Kuiper belt
B. L. de Vries, B. Acke, J. A. D. L. Blommaert +20
Some planetary systems harbour debris disks containing planetesimals such as asteroids and comets. Collisions between such bodies produce small dust particles, the spectral feature…
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…
Water production in comet 81P/Wild 2 as determined by Herschel/HIFI
M. de Val-Borro, P. Hartogh, J. Crovisier +42
The high spectral resolution and sensitivity of Herschel/HIFI allows for the detection of multiple rotational water lines and accurate determinations of water production rates in c…
First results of Herschel/PACS observations of Neptune
E. Lellouch, P. Hartogh, H. Feuchtgruber +51
We report on the initial analysis of a Herschel/PACS full range spectrum of Neptune, covering the 51-220 micrometer range with a mean resolving power of ~ 3000, and complemented by…
The Herschel-SPIRE submillimetre spectrum of Mars
B. M. Swinyard, P. Hartogh, S. Sidher +44
We have obtained the first continuous disk averaged spectrum of Mars from 450 to 1550 Ghz using the Herschel-SPIRE Fourier Transform Spectrometer. The spectrum was obtained at a co…
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…
