The Potential of the Timing Method to Detect Evolved Planetary Systems

Roberto Silvotti, Robert Szabo, Pieter Degroote +2

The timing method, using either stellar pulsations or eclipse timing of close binaries as a clock, is proving to be an efficient way to detect planets around stars that have evolve…

An Inner Gaseous Disk around the Herbig Be Star MWC 147

T. Bagnoli, R. van Lieshout, L. B. F. M. Waters +5

We present high-spectral-resolution, optical spectra of the Herbig Be star MWC 147, in which we spectrally resolve several emission lines, including the [O I] lines at 6300 and 636…

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…

The Vega Debris Disc: A view from Herschel

B. Sibthorpe, B. Vandenbussche, J. S. Greaves +37

We present five band imaging of the Vega debris disc obtained using the Herschel Space Observatory. These data span a wavelength range of 70-500 um with full-width half-maximum ang…

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…

Debris Disks around Solar-Type Stars: Observations of the Pleiades with Spitzer Space Telescope

J. M. Sierchio, G. H. Rieke, K. Y. L. Su +3

We present Spitzer MIPS observations at 24 um of 37 solar-type stars in the Pleiades and combine them with previous observations to obtain a sample of 71 stars. We report that 23 s…

The lunar phases of dust grains orbiting Fomalhaut

M. Min, M. Kama, C. Dominik +1

Optical images of the nearby star Fomalhaut show a ring of dust orbiting the central star. This dust is in many respects expected to be similar to the zodiacal dust in the solar sy…
